What Size Tank Does a Amano Shrimp Need?
Minimum tank: 10 gallons
A Amano Shrimp (Caridina multidentata) grows to about 2 in (5.1 cm), so the practical minimum is a 10-gallon aquarium. A pair or small group is typical, so leave a little extra room for tankmates.
| Single fish or pair | 10 gallons |
|---|---|
| Comfortable group | 10 gallons |
| Community setup | 20 gallons+ |
Bigger is easier: more water dilutes waste and holds temperature and pH steady. See stocking ideas for a 10-gallon tank or try the stocking calculator.
