How Many Kuhli Loach in a 125-Gallon Tank?
In a 125-gallon tank you can comfortably keep about 5–44 Kuhli Loach. As a schooling species, never keep fewer than 5.
Why
Stocking is driven by adult size and waste output, not just fish count. Kuhli Loach reaches about 4" with a moderate bioload, and needs 73–86°F water at pH 5.5–7. Always cycle the tank and test water before adding livestock.
