How Many Dwarf Gourami in a 125-Gallon Tank?
In a 125-gallon tank, plan on about 1–2 Dwarf Gourami, leaving room for tankmates and filtration headroom.
Why
Stocking is driven by adult size and waste output, not just fish count. Dwarf Gourami reaches about 3.5" with a moderate bioload, and needs 74–82°F water at pH 6–7.5. Always cycle the tank and test water before adding livestock.
