How Many Flag Acara in a 75-Gallon Tank?
In a 75-gallon tank, plan on about 1–2 Flag Acara, leaving room for tankmates and filtration headroom.
Why
Stocking is driven by adult size and waste output, not just fish count. Flag Acara reaches about 3" with a moderate bioload, and needs 72–82°F water at pH 6–7.5. Always cycle the tank and test water before adding livestock.
