Diet

Carnivorous. Assassin Snails primarily feed on other snails, especially pest snails like Malaysian Trumpet Snails and Ramshorn Snails. They are effective natural predators and can help control snail populations in the aquarium. If pest snails are scarce, they may also accept sinking pellets or frozen foods.

Community Compatibility

Assassin Snails can be kept with peaceful community fish, but caution should be exercised when keeping them with small, slow-moving fish or shrimp. They may view small fish or shrimp as potential prey. Compatible tank mates include larger tetras, rasboras, gouramis, and other non-aggressive fish species.

Gender Differences

Assassin Snails have separate sexes, with males typically being smaller and having a more slender shell compared to females.
