Amano Shrimp Minimum Tank Size
The minimum tank size for amano shrimp is 10 gallons. Here is why, plus group size and the best tankmates.
Quick answer
10 gallons
The minimum tank size for amano shrimp is 10 gallons. Keep a group of 3 or more.
The recommended minimum tank size for amano shrimp is 10 gallons. Amano shrimp are larger algae-eating shrimp that are more active than cherries and do not breed in freshwater. A 10-gallon gives a small group room to forage among plants and hardscape. Bigger is always better: a larger tank is more stable and more forgiving, so treat 10 gallons as a floor rather than a target.
Set up a 10-gallon amano shrimp tank
A 10-gallon (or larger) tank is the right starting size for amano shrimp.
Most of these species need a stable tropical temperature.
Cycle the tank and keep ammonia and nitrite at zero before adding livestock.
Why amano shrimp need at least 10 gallons
Amano shrimp are larger algae-eating shrimp that are more active than cherries and do not breed in freshwater. A 10-gallon gives a small group room to forage among plants and hardscape. Tank size is not just about the fish fitting in the water; it is about swimming room, water stability, and bioload. A larger volume dilutes waste, holds temperature and chemistry steadier, and gives amano shrimp room to behave naturally. Cutting below 10 gallons tends to mean more stress, more aggression, and more frequent water problems.

Group size and behavior
Keep a group of 3 or more. Getting the social setup right matters as much as the gallons, so follow the group guidance above when you stock the tank. For the full picture on diet, water parameters, and breeding, see the full amano shrimp care guide.
Good tankmates for amano shrimp
Amano Shrimp generally do well with calm, similarly sized companions. A few reliable options:
- peaceful community fish
- snails
- small tetras
Always confirm that any tankmate shares the same temperature and water-chemistry needs, and that your tank is large enough for everyone combined. Use the stocking calculator to check the full bioload before you add fish.
Plan the tank
Once you have settled on a tank, size the gear with the 10-gallon tank setup guide and confirm the volume with the minimum tank size calculator.

The recommended minimum tank size for amano shrimp is 10 gallons. Amano shrimp are larger algae-eating shrimp that are more active than cherries and do not breed in freshwater. A 10-gallon gives a small group room to forage among plants and hardscape. Treat that as a floor, since a larger tank is more stable and more forgiving.
Can you keep amano shrimp in a smaller tank?
Going below 10 gallons usually means more stress, more aggression, and faster swings in water quality. The extra volume of the recommended size dilutes waste and steadies temperature and chemistry, which keeps amano shrimp healthier. Bigger is better whenever you have the space.
How many amano shrimp should you keep together?
Keep a group of 3 or more. Follow that social guidance closely, since getting the group right matters as much as the tank size.
What are good tankmates for amano shrimp?
Amano Shrimp do well with calm, similarly sized companions such as peaceful community fish, snails, small tetras. Always confirm shared temperature and water-chemistry needs, and run the full stock list through a stocking calculator so you do not overload the tank.
