How Many Giant Gourami in a 125-Gallon Tank?
In a 125-gallon tank, plan on about 1–1 Giant Gourami, leaving room for tankmates and filtration headroom.
Why
Stocking is driven by adult size and waste output, not just fish count. Giant Gourami reaches about 24" with a heavy bioload, and needs 68–86°F water at pH 6.5–8. Always cycle the tank and test water before adding livestock.
