How Many African Butterfly Fish in a 125-Gallon Tank?
In a 125-gallon tank, plan on about 1–2 African Butterfly Fish, leaving room for tankmates and filtration headroom.
Why
Stocking is driven by adult size and waste output, not just fish count. African Butterfly Fish reaches about 4" with a moderate bioload, and needs 73–86°F water at pH 6–7.5. Always cycle the tank and test water before adding livestock.
