In a 75-gallon tank you can comfortably keep about 6–12 Turquoise Rainbowfish. As a schooling species, never keep fewer than 6.
Why
Stocking is driven by adult size and waste output, not just fish count. Turquoise Rainbowfish reaches about 4.5" with a heavy bioload, and needs 75–82°F water at pH 7–8.5. Always cycle the tank and test water before adding livestock.
