How Many Bala Shark in a 125-Gallon Tank?
In a 125-gallon tank you can comfortably keep about too few for a proper school Bala Shark. As a schooling species, never keep fewer than 4.
Why
Stocking is driven by adult size and waste output, not just fish count. Bala Shark reaches about 12" with a heavy bioload, and needs 72–82°F water at pH 6–8. Always cycle the tank and test water before adding livestock.
