How Many Ropefish in a 125-Gallon Tank?
In a 125-gallon tank you can comfortably keep about 3–3 Ropefish. As a schooling species, never keep fewer than 3.
Why
Stocking is driven by adult size and waste output, not just fish count. Ropefish reaches about 15" with a heavy bioload, and needs 72–82°F water at pH 6–7.5. Always cycle the tank and test water before adding livestock.
