How Many Flowerhorn in a 75-Gallon Tank?
A 75-gallon tank suits 1 Flowerhorn. This species is territorial and is best kept singly unless the tank is large enough to break up aggression.
Why
Stocking is driven by adult size and waste output, not just fish count. Flowerhorn reaches about 12" with a heavy bioload, and needs 80–86°F water at pH 7–8. Always cycle the tank and test water before adding livestock.
