Best Freshwater Shrimp Tanks for Cherry Shrimp

Best Freshwater Shrimp Tanks for Cherry Shrimp: Choose by Space, Stocking, and Upkeep

The best freshwater shrimp tanks for cherry shrimp are usually rectangular aquariums in the 10–20-gallon range, with a gentle, shrimp-safe filter, mature planted surfaces, and enough room for stable water conditions. A 5-gallon tank can work for a small colony, but it leaves less margin for missed maintenance or sudden changes. Choose the volume and filtration around your space and experience—not just the number of shrimp you hope to keep.

Tank sizes compared

Tank dimensions and actual water volume vary by manufacturer and setup. The figures below are common nominal sizes; substrate, decorations, and an air gap reduce the water volume the aquarium holds. Approximate empty weights are for the glass tank alone and vary with glass thickness.

For a rough support check, a filled aquarium can weigh about 10–12 lb per gallon once water, substrate, and décor are included. That puts a 10-gallon setup around 100–120 lb and a 20-gallon setup around 200–240 lb. Use a stand designed for aquariums, support the full base, and follow the tank maker’s placement instructions.

Pick the tank that matches your situation

Filtration: protect shrimp, not just the water

Cherry shrimp (Neocaridina davidi) graze on biofilm and algae across plants, wood, and other surfaces. Filtration needs to support biological stability without creating a strong current or pulling in shrimplets.

• Sponge filter: A strong default for shrimp-only tanks. It provides biological filtration and gentle flow. Keep the sponge submerged during cleaning and rinse it in removed aquarium water, not untreated tap water, to avoid damaging beneficial bacteria.
• Hang-on-back filter: Useful when you want equipment outside the tank. Cover the intake with a shrimp-safe sponge pre-filter, and check that the outflow does not create a high-current zone.
• Internal filter: Can save space and provide adjustable flow. Protect its intake, and make sure the filter body does not take up too much of a small tank.

Do not replace or deep-clean all filter media at once. That can remove much of the biological filtration the tank depends on. If flow drops, first inspect for debris; clean only what is needed, gently, and preserve established media.

Planted layouts that make maintenance easier

Prioritize usable surface area and access over a crowded display. A useful layout leaves an open front area for feeding and siphoning, while plants and hardscape offer hiding places and grazing surfaces. Mosses, such as Java moss, and hardy plants such as Anubias or Java fern can provide cover; attach rhizome plants to wood or rock rather than burying their rhizomes in substrate.

Use a light that suits the plants you choose. More intense light can mean faster algae growth and more trimming, not automatically healthier shrimp. Avoid copper-based treatments and fertilizers unless their suitability for invertebrates is clear on the label; copper toxicity depends on concentration and water chemistry. Do not add algaecides to a shrimp tank without confirming they are safe for shrimp.

A bare-bottom tank is easier to vacuum but offers less planted area and can look stark. Inert sand or gravel is a straightforward choice for cherry shrimp. Active substrates can alter pH and water chemistry, so they are not necessary for Neocaridina and should be selected only if you understand the resulting parameters.

Cycle first, then add shrimp

A new aquarium is not ready just because the water looks clear. Before adding shrimp, establish biological filtration and confirm that the tank can process waste. Use an aquarium test kit to check ammonia, nitrite, and nitrate. A completed cycle should show zero ammonia and zero nitrite, with nitrate controlled through water changes and planting. Follow a fishless cycling method and test regularly; the timeline varies, so use test results rather than a fixed number of days.

Cherry shrimp generally do best with stable conditions, not frequent attempts to chase an exact “perfect” number. A commonly used starting range is about 68–78°F (20–26°C), pH 6.5–8.0, and moderate hardness, but source water and local shrimp lines differ. Check the seller’s water conditions where possible and avoid abrupt changes. If using a heater, choose one appropriate to the tank and room temperature, and use a thermometer to verify the result.

Maintenance that protects stability

For a 10-gallon tank, a weekly water change of roughly 10–20% is a reasonable starting point, adjusted for stocking, feeding, and test results. That is about 1–2 gallons per week. Match the replacement water’s temperature and treat tap water with a suitable dechlorinator. Pour it in slowly; a sudden large change can stress shrimp. Smaller, consistent changes are usually easier to manage than infrequent, very large ones.

• Feed sparingly: offer only what the colony consumes within a few hours, and remove leftovers. Uneaten food can degrade water quality.
• Top off evaporation with suitable fresh water; evaporation leaves minerals behind, so topping off with mineralized water can gradually raise hardness.
• Trim plants and clear dead leaves before they decay. Avoid disturbing the whole substrate during routine cleaning.
• Check the intake sponge and filter flow regularly, especially after plant trimming or heavy feeding.
• Acclimate new shrimp slowly, particularly if their transport water differs from the tank. Avoid pouring shipping water into the aquarium.

Bottom line

For most beginners, a 10-gallon rectangular aquarium with an air-driven sponge filter, easy-care plants, and a fully cycled, stable setup is the most balanced choice. Pick 5 gallons when space is the overriding constraint and you can maintain it consistently; choose 20 gallons if you want room for a larger colony and can support the extra weight. Across all sizes, protected intakes, mature biofilm, and gradual maintenance matter more than an elaborate tank kit.
