How Many Lyretail Killifish in a 75-Gallon Tank?
In a 75-gallon tank, plan on about 1–2 Lyretail Killifish, leaving room for tankmates and filtration headroom.
Why
Stocking is driven by adult size and waste output, not just fish count. Lyretail Killifish reaches about 2.4" with a moderate bioload, and needs 68–75°F water at pH 6–7. Always cycle the tank and test water before adding livestock.
