How Many Denison Barb in a 75-Gallon Tank?
In a 75-gallon tank you can comfortably keep about 6–7 Denison Barb. As a schooling species, never keep fewer than 6.
Why
Stocking is driven by adult size and waste output, not just fish count. Denison Barb reaches about 6" with a heavy bioload, and needs 60–77°F water at pH 6.5–7.8. Always cycle the tank and test water before adding livestock.
