TankStockingMystery Snail Tank Mates
Mystery snails are peaceful, hardy algae-grazers — an easy clean-up companion for almost any community.
They mind their own business, do not breed out of control in the way pest snails do, and clear the engine against nearly every fish. The only watch-outs are known snail-eaters (loaches, pufferfish) and fish that might nip their tentacles. Hard water keeps their shells healthy.

What fish can live with mystery snails?
Almost any peaceful community fish: tetras, rasboras, livebearers, corydoras and gouramis. Avoid snail-eaters such as loaches, pufferfish and assassin snails, plus fin-nippers that pester their tentacles.
Do mystery snails reproduce rapidly?
No — unlike pest snails, they lay distinctive above-water egg clutches you can simply remove, so they do not overrun a tank.
Do mystery snails need special water?
They need enough calcium for a healthy shell, so moderately hard water (or a calcium supplement) is ideal. Soft, acidic water pits and erodes their shells over time.
