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