How Many Bolivian Ram in a 40-Gallon Tank?
In a 40-gallon tank, plan on about 1–2 Bolivian Ram, leaving room for tankmates and filtration headroom.
Why
Stocking is driven by adult size and waste output, not just fish count. Bolivian Ram reaches about 3" with a moderate bioload, and needs 72–79°F water at pH 6–7.5. Always cycle the tank and test water before adding livestock.
