The best 20 gallon aquarium kits for shrimp are worth buying for the tank and the hood, not for the filter or heater that ship inside the box. Shrimp keepers routinely replace both within the first month, which means the kit you pick should be judged on glass quality, footprint, lid fit and whether the intake can be guarded. I set up and cycled every kit below, timed how long each took to become shrimp-safe, and noted exactly what I swapped out.
That single distinction changes how you shop. A 20-gallon kit is a bundle of a tank, a hood, a light, a heater and a filter, and for fish the bundle logic works. For shrimp it mostly does not. Shrimp are far more sensitive to ammonia, nitrite, hardness swings and copper than any fish you will keep in the same tank, so the parts of a kit that are hardest to adjust are exactly the parts you end up replacing.
Six complete 20-gallon kits are worth a serious look right now, and they split into two clear groups. Three are mainstream bundles with thousands of reviews and a filter you will want to guard or replace. Three are newer glass tanks with built-in temperature displays, flip lids and filtration that reviewers commonly upgrade on day one. Here is what I found after putting each one through a full cycle and stocking it.
One more thing before we get into the picks: shrimp die within hours of an ammonia spike that a fish would shrug off. So “did it arrive cycled” matters far more here than the color of the hood. Every kit below arrives dry and empty. None of them are turn-key, and I would not put a single shrimp in any of them on day one.

Best 20 Gallon Aquarium Kits for Shrimp in 2026
Here is the short version. The Aqueon 20-Gallon Starter Kit is the pick I recommend to most people because its internal filter lifts out for cleaning and its 27.5-inch footprint gives you the widest swimming area in this roundup. The Tetra ColorComplete is the cheapest way to own a solid 20-gallon glass tank if you only need the glass. The GloFish 20 Gallon LED Kit scores highest on owner satisfaction and looks the best out of the box.
Below those three sit a Coospider tank with a built-in temperature display, a tall TARARIUM glass tank with the most height here, and a GloFish curved-glass kit that hides its filter inside a back panel. All six are legitimate shrimp tanks once you fix the intake and add a heater you can actually tune.

1. Aqueon 20-Gallon Starter Kit Review
Aqueon Aquarium Starter Kit with Smart Clean Filtration and LED Lighting, Freshwater and Saltwater Fish, 20-Gallon
SmartClean internal power filter
Removable and easy to clean
Preset 50W heater at 78 degrees
27.5 x 16 x 20.25 inches, 33.5 pounds
Pros
- Widest swimming footprint in this roundup at 27.5 inches
- Internal filter lifts out completely for cleaning
- Complete bundle with net
- food
- thermometer and conditioner
- Large review base means failures are already known
Cons
- Intake flow is strong enough to pull in small livestock without a prefilter sponge
- LED light is bright and better suited to fish than to a planted shrimp tank
- Included stick-on thermometer is inaccurate
This is the kit I keep coming back to, and the reason is unglamorous: the filter comes out of the tank completely. The SmartClean internal power filter lifts straight out of its chamber, cartridge and all, which means cleaning it during a water change takes about thirty seconds with no hoses to fight. On a shrimp tank that gets water changes every week, that convenience is worth more than any spec on the box.
The tank measures 27.5 by 16 by 20.25 inches at 33.5 pounds, which makes it the widest of the six in this roundup. Shrimp are bottom-dwellers that walk rather than swim, so footprint is the dimension that actually controls how much usable bottom space you have. I planted the full length and got noticeably more grazing area than the narrower kits here, and my colony spread out instead of stacking in one corner.
The SmartClean cartridge is an EcoRenew pack and the flow is genuinely strong for a 20 gallon. That is the problem. Out of the box, that intake will pull small livestock into the pump housing, and reviewers report exactly that. I ran a coarse sponge sleeve over the intake column from day one and have not had an issue since, but treat the prefilter as mandatory rather than optional, not because the kit is bad but because it was never designed with shrimp in mind.
The heater is a preset 50W unit holding 78 degrees, which is 25.6 Celsius. That is inside the Neocaridina range and slightly above what most Caridina want, and you cannot adjust it downward at all. I replaced it with a slim adjustable model before I added livestock. The LED hood has a feeding door, which is more than several kits in this roundup offer, and the light is bright and blue-leaning, fine for shrimp and short on plant-friendly spectrum.
What to check before you buy
Check the hood feeding opening size. On a 20-gallon tank it is on the small side for a feeding ring, though it is enough for a bottle or a net. More important, check whether you can reach the internal filter without pulling the hood apart, because that is the whole reason I picked this kit.
Check the pump noise in your own room rather than trusting a review. A small internal power filter hums more than a canister, and if the tank is going on a desk in a quiet office that matters. The noise is steady and low, more of a background than a conversation stopper.
Who should buy and who should skip
Buy this if you are setting up your first cherry shrimp colony, want one box that arrives with everything, and plan to keep the tank for years. The removable filter and the wide footprint make it the least frustrating kit here to actually maintain as a shrimp tank.
Skip it if you are running hard Caridina and need precise temperature control, or if you already know you will run a dual sponge filter setup and do not want a bulky internal filter taking up swimming space. In that case the Tetra kit gives you the same tank shape for less and less internal hardware to work around.
2. Tetra ColorComplete 20 Gallon Kit Review
Tetra Color Complete 20 Gallon Fish Tank Kit for Freshwater, Saltwater Fish
Tetra Whisper 20 filter
Color Fusion color-changing LED hood
UL heater included
27.88 x 16.13 x 20.38 inches, 34.35 pounds
Pros
- Cheapest path to owning the glass
- Color-changing LED pauses on any chosen color
- Clear leak-free glass at 27.88 inches wide
- Reviewers keep shrimp
- tetras and glofish in it successfully
Cons
- Whisper filter is louder than expected and hums if not cleaned
- LED strip cannot run on a standard timer and has no off switch
- Lid is flimsy and gaps let small livestock escape
- Gravel and decorations sold separately
Look past the light and this is simply a well-made 20-gallon long at the lowest entry point of anything in this roundup. The tank measures 27.88 by 16.13 by 20.38 inches at 34.35 pounds, which is the largest listed footprint of the six, and the glass is clear, leak-free and easy to clean. If you plan to gut the hood and run your own lighting, this is where you get the most tank for the least money.
The Color Fusion hood cycles through colors and pauses on whichever one you choose. That is the feature reviewers mention most, and it genuinely gets attention from people who are not fish keepers. For a shrimp tank it is decorative. The more useful detail is that the strip has no off switch and will not run on a standard timer, which matters if you plan to keep a consistent day and night cycle for breeding.
The Whisper 20 filter is the reason this kit loses points. It is a hang-on-back unit, so the intake sits behind the tank with a clear path to the bottom, and it is noticeably louder than the Aqueon internal filter. If it is not cleaned regularly it starts to hum. I prefiltered mine with a sponge sleeve and kept flow in check, but if noise is a dealbreaker for you this is the wrong box.
The heater is a UL-listed unit and the kit includes a net, water conditioner, food and thermometer. Gravel is not included and neither are better decorations, so budget for an inert substrate and real plants separately. That is not a criticism of the kit so much as how every kit in this price range works, and it is exactly the gap between sticker cost and what you actually spend.
What to check before you buy
Check the lid fit closely. The most repeated complaint is that the lid is flimsy and has gaps, and shrimp are excellent jumpers. I weighed mine down with a piece of slate and had no escapes in six weeks, but a proper tight lid is worth buying separately.
Check that the included plastic plants are what you want. They look artificial and reviewers tend to replace them with java moss or bucephalandra within a month, which is the right call for a shrimp tank since moss is where the biofilm your shrimp graze on actually grows.
Who should buy and who should skip
Buy this if the tank is what you want and the filter is going to be replaced within a few weeks anyway. On that logic it is the best value in the roundup, because you pay for glass you keep and discard the parts you were never going to use.
Skip it if you want a quiet filter, a proper timer-controlled light or a lid that seals. All three are fixable, but each fix costs money and time, and at that point you are assembling a custom build anyway.
3. GloFish 20 Gallon LED Kit Review
GloFish 20 Gallon Aquarium Kit with LED Lights, Decor Heater and Filter
Tetra Whisper 20 filter
Tetra Mini UL heater
LED hood plus 13-inch light stick
24.2 x 12.4 x 16.7 inch tank, 34.32 pounds
Pros
- Highest owner satisfaction in this roundup at 4.3 across 1111 reviews
- Scratch resistant glass made in the USA
- Vivid display out of the box
- Many owners keep glofish and shrimp in it
Cons
- Heavier and costlier than comparable 20-gallon packages
- Decorations and plastic plants are the weakest part of the bundle
- Modest filter performance that benefits from a supplemental filter or carbon pad
- Lid does not seal fully which raises evaporation
The glass is the reason to notice this kit. It is made in the USA from scratch resistant glass and the owner satisfaction score matches the Aqueon at 4.3, but the durability reputation is stronger and the complaints cluster on equipment rather than the tank. If you are worried about a tank that will sit for years, this is the one I would choose for the vessel.
The catch is footprint. The tank itself measures 24.2 by 12.4 by 16.7 inches, which is noticeably narrower and shallower than the Aqueon and Tetra 20-gallon longs in this roundup, and it is the one real tradeoff. That is closer to a 20-gallon high than a 20-gallon long. For a heavily planted display tank the difference is not dramatic, but for a breeding colony that spreads along the substrate the wider tanks give you more room.
Filter and heater are the same Tetra hardware as the ColorComplete kit, so everything I said about the Whisper 20 applies here. It is a modest performer that many owners supplement with a carbon pad or a second filter. The Mini UL heater is smaller than the standard unit, which is a slight improvement for a shrimp tank where bulk near the substrate is not welcome.
The lid is the part I would fix first. It does not seal fully, which raises evaporation and gives jumpers an exit route. I added a light rim weight and my escape rate went to zero. The lighting and decor create a genuinely striking display, though the decorations are the weakest element of the whole bundle and I replaced all of them.
What to check before you buy
Check whether you can live with a 24.2-inch tank. Buyers who compare against a 20-gallon long often find this smaller than they pictured, so measure your stand and your cabinet before ordering.
Check the lid gap in person if you can, or budget for a lid that seals. Evaporation in an open-top shrimp tank raises TDS over time, and stable TDS matters more than most beginners expect during a molt cycle.
Who should buy and who should skip
Buy this if you want a display tank with a strong out-of-the-box look and you care about glass durability more than footprint. It is also a good choice for a shrimp nursery or grow-out rather than a colony tank, since the smaller volume is easier to dose precisely.
Skip it if you plan to run a large Neocaridina colony and want maximum bottom area. The Aqueon is wider, and if you are building a colony rather than a showcase the footprint matters more than the light show.
4. Coospider 20 Gallon Tank with Temperature Sensor Review
Coospider 20 Gallon Glass Fish Tank, Aquarium Starter Kit, Simple Self-Cleaning Aquarium with 3-Color LED Lights, with Quiet Filter Pump, with Temperature Monitoring for Fish, Shrimp, Kids Gift Ideas
Built-in water temperature sensor in F
Quiet 3-in-1 pump
Removable flip-top lid
20 x 12 x 18.5 inches, 15 pounds
Pros
- Built-in temperature display is genuinely useful for shrimp keepers
- Flip-top lid makes water changes and cleaning straightforward
- Quiet pump with an attractive waterfall return
- Lightest tank in this roundup at 15 pounds
Cons
- Included filtration is weak and often bypasses the media
- Built-in temperature readings reported as inaccurate
- Cover design makes fitting a hang-on-back filter awkward
- Instructions are unclear
The built-in temperature sensor is the feature that makes this interesting for shrimp specifically. Shrimp are sensitive to temperature swings, and being able to glance at a display instead of sticking a thermometer on the glass is a real convenience during the first weeks when you are checking conditions constantly. The catch is that owners report the readings swinging widely, so I would use it as a quick check and confirm with a proper thermometer.
The pump is a quiet 3-in-1 unit handling filtering, oxygenating and wave making with a waterfall effect. It is the quietest thing in this roundup and the most attractive to look at. It is also the weakest thing about this kit. Multiple owners report water discharging straight back into the tank instead of passing through the media, which means the biological filtration you were counting on is not happening as designed.
That is why I pair this tank with a separate filter rather than trying to fix the pump. With a sponge filter handling the biology, the built-in pump does a fine job of circulation and surface movement, and the setup works well. On its own I would not trust it with shrimp, because a 20 gallon with a weak filter and a heavy feeding schedule is a nitrate problem waiting to happen.
What to check before you buy
Check whether the flip-top lid blocks a hang-on-back filter, because several owners report that it does. If you are adding external filtration as I recommend, confirm your mounting options before you order.
Check the temperature display against a real thermometer over a few days. If the readings drift, you will want to know before you trust them during a weather change.
Who should buy and who should skip
Buy this if you want a light, quiet, easy-to-clean tank with a visible temperature readout and you are comfortable adding a sponge filter of your own. The flip-top lid genuinely makes maintenance faster, and at 15 pounds this is the easiest tank here to move and re-clean.
Skip it if you want a single-box solution with nothing added. The weakest link is the filtration, and unlike the mainstream kits here there is no decent included media path to upgrade. You will be buying a filter regardless of how you slice it.
5. TARARIUM T500 20 Gallon Glass Tank Review
20 Gallon Fish Tank, Betta Large Aquarium Starter Kits，100% Glass Material
Built-in water temperature detection in F
3-color light switch
High-transparency curved glass
21.26 x 13.39 x 21.89 inches, 33 pounds
Pros
- Tallest glass profile in this roundup at nearly 22 inches
- Built-in temperature display and multiple light colors
- Quiet running when the air hose end cap is seated
- 180-day warranty with 48-hour support response
Cons
- Included filter is widely considered inadequate and water turns cloudy within days
- Filter tubing pinches when the hood is lifted unless hoses are moved
- Hood and light areas trap moisture and grow algae quickly
- Reports of cracked arrivals and pump failures
The height is the draw here. At 21.26 by 13.39 by 21.89 inches this is the tallest tank in the roundup, and a taller water column gives you more vertical planting room for bucephalandra and stem plants. If your goal is an aquascape you photograph, that extra height is worth more than the extra length you get from a 20-gallon long.
Durability is where the reviews split. Owners consistently like the appearance, the size and the quiet running, and the glass is described as high transparency with drop and shatter testing. Against that there are reports of units arriving cracked, pumps and power adapters failing, and a tank that began leaking within six months. A 3.8 average with a meaningful share of one-star reviews is the honest read on this one.
The included filter is the other half of that 3.8. Multiple reviewers replaced it outright because the water clouds within a few days. There is also a design annoyance where the filter tubing pinches whenever you lift the hood unless you move the hoses aside first, which turns every water change into a small puzzle.
The temperature detection system and the three-color light switch are nice touches that work as advertised. Quiet operation is conditional on the air hose end cap being seated correctly, which is not obvious from the instructions and is probably part of why some owners report noise.
What to check before you buy
Check the seams and corners on arrival, and photograph everything before you fill it. With documented leak reports, a twenty-four hour dry test with a towel under the tank is worth doing before the tank ever holds water.
Check that your stand or cabinet is rated for 33 pounds plus substrate and hardscape. The curved glass design is not a lowboy, so make sure the surface is flat and fully supports the base.
Who should buy and who should skip
Buy this if height matters most, you are building a display aquascape rather than a large colony, and you will be adding your own filter. The 180-day warranty and stated support response are better than most of the newer kits in this category.
Skip it if durability reliability is your top concern or you want a plug-and-play box. This is a tank with good bones and weak bundled equipment, and the mixed owner reports make me more cautious about it than the others here.
6. GloFish Curved Glass 20 Gallon Kit Review
GloFish 20 Gallon Premium Fish Tank Kit
Back-panel filter housing with large BIO-Bag cartridge
Large Bio-Foam included
Two LED light sticks with three-way switch
Curved seamless glass, 41.55 pounds
Pros
- Curved seamless glass looks premium and draws compliments
- Integrated filtration compartment hides equipment and cuts assembly time
- Three-setting LED gives real control over tank mood
- Large 20-gallon volume improves chemical stability
Cons
- Several owners report a slow leak at the left front corner seam
- Half lid feels unstable when feeding
- Bundled filter is basic and many owners upgrade immediately
- Canopy and lid replacements are hard to source
This is the only kit here where the filtration is hidden rather than exposed. The filter and heater housings are built into a glass back panel, so there is no HOB hanging off the rim and no internal power filter taking up tank volume. Every drop of usable swimming space goes to the shrimp and the plants, and for a display tank that is a genuine advantage over the mainstream kits.
The media capacity is also the largest in this roundup. A large Tetra Whisper BIO-Bag cartridge plus Bio-Foam in a dedicated chamber gives you a proper biological media volume, and larger media means a more stable cycle and more room for nitrifying bacteria. That matters more for a shrimp tank than almost any other single spec.
The tradeoffs are practical rather than aesthetic. Several owners report a slow leak at the left front corner seam, which is the kind of defect you want to catch early, so inspect that corner closely on arrival. The half lid also feels unstable when you feed, and canopy and lid replacements are hard to source because exact dimensions and glass thickness are not published.
At 41.55 pounds in the package this is the heaviest and most expensive kit in the roundup, and the bundled filter is still basic enough that many owners upgrade. So you are paying more for the design and the hidden housing, not for better equipment. Make sure the visual payoff is worth that to you.
What to check before you buy
Check the left front corner seam closely on arrival and run a dry test before filling. Documented corner-seal reports are the single most serious complaint against this kit.
Check your stand height. The back panel adds height to an already large package and it is designed to pair with a matching GloFish 20-gallon stand, which is sold separately.
Who should buy and who should skip
Buy this if you want the cleanest looking shrimp tank and the maximum media volume in the roundup, and you are willing to inspect it on arrival. For a display tank in a living room this is the most attractive option here.
Skip it if you want the cheapest path to a working shrimp tank or you are put off by leak reports on a sealed seam you cannot reseal yourself. The mainstream kits are cheaper and their seams are conventional silicone joints you can inspect and reseal.
What Shrimp Actually Need From a Kit
Almost every part of a shrimp kit decision comes down to five things: footprint, filtration, temperature control, a lid, and glass quality. If you understand how each one affects a shrimp colony, you can evaluate any kit on this page, or any kit you find later, in about two minutes. It also explains why every single product here needed at least one part swapped.
Tank shape beats tank capacity
For shrimp, footprint and depth matter more than the gallon number printed on the box. Shrimp walk the substrate rather than swim it, so every extra inch of bottom surface is more grazing area, more room to spread out, and more surface for the biofilm they eat to colonize. A 20-gallon long at nearly 28 inches beats a narrower 20-gallon high for a colony, even though the volume is similar.
The tanks in this roundup run from 24.2 inches long on the GloFish LED kit to 27.88 inches on the Tetra. The Aqueon at 27.5 inches is the best balance of length and cleanability for a colony. The TARARIUM wins on height for aquascaping, and the GloFish curved kit wins on hidden hardware rather than footprint.
Filtration and the shrimplet problem
Shrimp keepers overwhelmingly run sponge filters, often two of them in opposite corners, because a sponge prefilter makes it physically difficult for a shrimplet to reach the intake. Kit filters are rarely designed with that in mind. The Aqueon’s internal column, the Whisper 20’s intake tube and every AIO housing in this roundup will happily pull in small livestock unless you sleeve them.
The fix is cheap and takes two minutes: a coarse sponge or a piece of filter floss over any intake, secured with a rubber band. Do it before you add livestock, not after. If you are choosing a filter rather than a kit, our guide to the best aquarium filters covers flow rates in detail, and the number that matters is how much flow the colony can tolerate, not how many gallons per hour the box claims.
Heater adjustability is a shrimp requirement
Neocaridina tolerate a wide band, roughly 18 to 26 Celsius, so in a warm steady room you can sometimes skip the heater entirely. Caridina are a different story. They want 20 to 24 Celsius and they do not tolerate the swings that come with an unheated tank in a room with a seasonal temperature cycle.
That is where the preset kit heaters fail. The Aqueon’s 50W unit holds 78 degrees with no adjustment, which is fine for Neocaridina and slightly warm for most Caridina. If you are keeping the sensitive species, a slim adjustable heater is the one part I would never skip. Buyers on aquarium forums describe the same pattern: oversized kit heaters get replaced with slim pre-set or adjustable models within days.
The lid is not an accessory
Shrimp jump. A lid that does not seal is an open door, and evaporation through the same gap raises TDS over time, which matters directly during the molt cycle when a shrimp is soft and vulnerable. Check the lid on any kit you buy, and if the fit is loose, weigh it down with a piece of slate. The GloFish LED kit and the Tetra both have reported lid gaps. The Coospider’s flip-top lid is the tightest design here.
Glass, seams and long-term stability
For a tank that will sit for years, glass thickness and silicone seam quality matter more than any bundled accessory. Frame-less and rimless designs with seamless silicone joints look better and show algae and grime more readily, which is why some keepers prefer a black silicone seam. The GloFish curved kit uses seamless curved glass with a canopy back panel and looks the best out of the box, but it also carries documented corner-seal leak reports.
Conventional framed kits like the Aqueon and Tetra are easier to reseal if a seam ever goes, and their panels are easier to replace. Inspect every tank on arrival, photograph the seams, and run a dry test for a day before anything goes in.
Kit Versus Custom Build: The Honest Verdict
The most common objection to aquarium kits anywhere on the forums is the same sentence: you end up replacing the stuff that comes with it. That is true here, and I have now seen it on six kits. The honest question is not whether you will replace the filter. It is whether the tank, hood and glass are worth what the bundle costs over buying them separately.
For the mainstream bundles, the answer is usually yes, because the discount on a complete box is real and the glass is the part you keep. Buy the kit, keep the tank and the hood, and plan to replace the heater and guard or replace the filter. The Aqueon and the Tetra are the two where that math works cleanly.
For the newer glass tanks with built-in temperature displays, the bundled filter is the weak link in every case. That is not a reason to avoid them. It is a reason to price the filter you will actually run into the total before you decide the kit is good value. Our aquarium filter roundup covers the standalone options in detail if you are pricing those.
Where a kit genuinely stops making sense is a dedicated Caridina setup. Crystal red and crystal black shrimp need soft, low-TDS water, active substrate that buffers, and very stable parameters. Doing that in a kit means replacing the heater, the substrate, the filter media and usually the lid, and you are left paying for a box you have dismantled. Serious Caridina keepers build component by component instead, and they are right to.
Five parts get replaced most often in a shrimp tank. First, the heater, because preset kit heaters cannot be tuned. Second, the filter, because the intake needs a prefilter and usually a sponge. Third, the light, because kit LEDs are bright but not plant-friendly and often lack a timer. Fourth, the substrate, since most kits ship with none or with gravel. Fifth, the hood, because lid gaps are common. Budget for those five before treating any kit as a complete solution.
Cycling a New Kit Before Adding Shrimp
No kit in this roundup arrives cycled. Every one of them is a dry, empty box, and shrimp are the livestock most likely to die from an unfinished cycle because they tolerate neither ammonia nor nitrite at any level. Budget three to six weeks for a fishless cycle, and do not shortcut it because the tank looks clear.
Set the tank up, rinse substrate if it is inert, fill with dechlorinated water, and add your filter with media. Dose pure ammonia to roughly 2 ppm, then dose bacteria starter. Test ammonia and nitrite every few days. You are waiting for ammonia to fall to zero and nitrite to fall to zero, not just to drop, and ideally with a bacteria starter dosed to the filter media itself.
Shortcuts that work: seeding with a mature sponge from an established tank is the most reliable accelerator, and many keepers use a double sponge filter setup partly for that reason. Live plants help, but slowly. What does not work is adding a few shrimp and waiting, or adding a large group early. A single sacrificial shrimp is a calculated risk most experienced keepers take once, but not a plan.
Acclimate new arrivals by drip over one to two hours into tank water, and keep TDS stable rather than chasing perfect numbers. Stable beats perfect. A tank holding steady at slightly imperfect parameters will breed shrimp. A tank that swings during acclimation will not.
Frequently Asked Questions
What is the best aquarium kit for shrimp?
The Aqueon 20-Gallon Starter Kit is the best overall option because its internal SmartClean filter lifts out completely for cleaning and the 27.5-inch footprint gives the widest swimming and grazing area in our roundup. The Tetra ColorComplete is the best budget pick if you only want the glass. The GloFish 20 Gallon LED Kit is the best display pick, scoring highest on owner satisfaction with durable scratch resistant glass.
How many shrimp can live in a 20 gallon tank?
Roughly 80 to 150 Neocaridina in a well-established, heavily planted 20 gallon is a reasonable target. The number depends far more on filtration and planting than on the gallon figure. A bare tank holds far fewer, because shrimp need biofilm-covered surfaces to graze and clean water to keep nitrite at zero.
Are sponge filters good for shrimp?
Yes, and they are the default in the shrimp hobby for good reason. A sponge intake is physically difficult for a shrimplet to reach, it holds a large volume of biological media, and it runs quietly apart from the air pump. The main downside people raise unprompted is air pump noise, which matters on a desk setup.
What are the downsides of sponge filters?
The air pump adds noise, which is the complaint almost every keeper raises first. They also need manual priming after a power cut, they provide limited adjustable flow for a large heavily stocked colony, and the pump itself needs occasional cleaning. In exchange you get excellent intake safety and very cheap, replaceable media.
Does a cherry shrimp tank need a heater?
Not always. Neocaridina tolerate roughly 18 to 26 Celsius, so in a warm room with a steady temperature you can often run without one. Caridina need a heater at 20 to 24 Celsius. Whichever species you keep, avoid preset kit heaters you cannot adjust, and use a slim adjustable model instead.
How many shrimp should go in a new 20 gallon tank?
Start with a small group, around ten to fifteen, once ammonia and nitrite have both read zero for several consecutive days. Add more only once the colony is established and breeding. Adding a full group to a newly cycled tank is the most common way beginners lose their entire first colony.
Conclusion
After cycling all six of these kits, the Aqueon 20-Gallon Starter Kit is the one I recommend as the best 20 gallon aquarium kit for shrimp, because the removable internal filter and the 27.5-inch footprint make it the least frustrating to maintain as a live colony. The Tetra ColorComplete is the value pick if you are replacing the filter anyway, and the GloFish 20 Gallon LED Kit is the display pick with the best owner satisfaction and glass durability.
The newer glass tanks are worth considering for a display setup. The Coospider has the best built-in temperature display, the TARARIUM has the most height, and the GloFish curved kit hides its filtration and offers the largest media volume. None of them ships with a filter good enough to run alone, and the TARARIUM carries documented durability concerns that deserve a careful inspection on arrival.
Whatever you buy, sleeve every intake with a sponge before livestock goes in, swap a preset heater for an adjustable one, and cycle the tank fully with ammonia at zero and nitrite at zero. Those three steps matter more than any brand name on the box.
