How Many Assassin Snail in a 125-Gallon Tank?
In a 125-gallon tank, plan on about 1–2 Assassin Snail, leaving room for tankmates and filtration headroom.
Why
Stocking is driven by adult size and waste output, not just fish count. Assassin Snail reaches about 1" with a light bioload, and needs 70–80°F water at pH 7–8. Always cycle the tank and test water before adding livestock.
