How Many Tropheus Duboisi in a 75-Gallon Tank?
In a 75-gallon tank you can comfortably keep about 6–10 Tropheus Duboisi. As a schooling species, never keep fewer than 6.
Why
Stocking is driven by adult size and waste output, not just fish count. Tropheus Duboisi reaches about 5" with a heavy bioload, and needs 75–82°F water at pH 7.8–9. Always cycle the tank and test water before adding livestock.
