Astrea Snail
Astraea tecta
One of the best reef algae-eating snails β effective grazer of microalgae and diatoms on rock and glass. Conical shell with star-like ridges. Cannot right itself if flipped, so monitor after storms of flow.
Bumblebee Snail
Engina mendicaria
Tiny, striking black and yellow banded snail. Buries in sand and hunts detritus and small worms β a useful sandbed cleaner. Larger specimens have been known to eat small sleeping fish, so use with caution.
Cerith Snail
Cerithium sp.
Small, elongated shell snail that works the sand bed, glass, and rocks. Excellent algae grazer and detritivore. Reproduces readily and stays small.
Fighting Conch
Strombus alatus
A sand-sifting powerhouse β plows through the sandbed consuming detritus, algae, and uneaten food. Lively and active, with eyes on stalks. The name comes from its aggressive response when flipped.
Margarita Snail
Margarites pupillus
Small, cold-water snail β an exceptional algae grazer often used in reef tanks as clean-up crew. Prefers cooler temperatures so it's ideal for FOWLR tanks or tanks below 74Β°F. Peaceful and prolific.
Nassarius Snail
Nassarius sp.
Small sand-dwelling scavenger that buries itself and erupts from the substrate to feed on meaty detritus. Excellent sand bed aerator and clean-up crew staple.
Stomatella Snail
Stomatella varia
Fast-moving, flat-shelled snail that looks more like a slug. Reproduces readily in reef tanks, forming beneficial colonies that graze film algae and coralline. Fish generally ignore them; a great hitchhiker species.
Tectus Snail
Tectus fenestratus
Larger turban-shaped snail with a heavily ridged shell. A workhorse algae grazer on rockwork and glass β handles tougher hair algae that smaller snails cannot manage. Peaceful and active.
Trochus Snail
Trochus sp.
Conical-shelled snail that rights itself when knocked over β unlike turbo snails. Efficient algae grazer on glass and rock. Reef-safe and long-lived.
Turbo Snail
Turbo fluctuosus
Heavyweight saltwater clean-up crew member. Excellent at mowing down hair algae on glass and rock. Can knock over frags β secure corals in its path.
