What Size Tank Does a Clown Loach Need?
Minimum tank: 75 gallons
A Clown Loach (Chromobotia macracanthus) grows to about 12 in (30.5 cm), so the practical minimum is a 75-gallon aquarium. Because the Clown Loach is a schooling fish, keep at least 5 together — a shoal needs more swimming room than one fish, so size up for a full group plus tankmates.
| Single fish or pair | 75 gallons |
|---|---|
| Comfortable group | 85 gallons |
| Community setup | 85 gallons+ |
Bigger is easier: more water dilutes waste and holds temperature and pH steady. See stocking ideas for a 75-gallon tank or try the stocking calculator.
