Malaysian Trumpet Snail tank mates

A working substrate snail, not a pest. Population scales with overfeeding. The fix for too many MTS is less food, not more chemicals.

Common mistakeTrying to wipe out Malaysian trumpet snails with assassin snails while still overfeeding is how keepers invent a bounce-back boom within weeks. The population tracks leftover food in the sand. Fix feeding first — assassins alone do not solve a food surplus in a messy tank.

Usually safer companions

Conservative shortlist from this profile. Open a pair page before you buy.

  • Corydoras CatfishPair check

    The Malaysian Trumpet Snail profile lists Corydoras Catfish as both safe and a recommended pairing. Corydoras Catfish schools in groups of 6 or more, so plan room for the whole group rather than one fish. Corydoras Catfish grows bigger than Malaysian Trumpet Snail (6cm vs 2.5cm). Stock the Malaysian Trumpet Snail group large enough to outnumber the Corydoras Catfish, or the smaller fish ends up bullied or off food.

  • Harlequin RasboraPair check

    The Malaysian Trumpet Snail profile lists Harlequin Rasbora as both safe and a recommended pairing. Harlequin Rasbora schools in groups of 6 or more, so plan room for the whole group rather than one fish. Harlequin Rasbora grows bigger than Malaysian Trumpet Snail (5cm vs 2.5cm). Stock the Malaysian Trumpet Snail group large enough to outnumber the Harlequin Rasbora, or the smaller fish ends up bullied or off food. Harlequin Rasbora swims in the middle zone while Malaysian Trumpet Snail stays in the bottom, so the two will not crowd the same water column.
