How Many Clown Loach in a 125-Gallon Tank?
In a 125-gallon tank you can comfortably keep about 5–7 Clown Loach. As a schooling species, never keep fewer than 5.
Why
Stocking is driven by adult size and waste output, not just fish count. Clown Loach reaches about 8" with a heavy bioload, and needs 77–86°F water at pH 6–7.5. Always cycle the tank and test water before adding livestock.
