How Many Mystery Snail in a 125-Gallon Tank?
In a 125-gallon tank, plan on about 1–2 Mystery Snail, leaving room for tankmates and filtration headroom.
Why
Stocking is driven by adult size and waste output, not just fish count. Mystery Snail reaches about 2" with a light bioload, and needs 68–82°F water at pH 7–8.5. Always cycle the tank and test water before adding livestock.
