Don't let the Cerith Snail's small (1/16-1/2) adult size fool you. As well as having a gorgeous, elongated spiral shell, this active scavenger can consume large amounts of detritus, uneaten food, fish waste, and algae. Plus, this species of the Cerithium genus often burrows in your aquarium sand and helps maintain adequate oxygen levels in the substrate.Native to the Caribbean and Eastern Pacific off the coast of Mexico, the Cerith Snail does best in larger, well-established reef systems with deep sand beds. This voracious feeder is most active at night. In fact, breeding pairs of Cerith Snails will lay their eggs on your aquarium glass just after dark in long, stringy curves. However, since these eggs take a while to develop, they are often consumed by other tankmates or removed from the water column by filtration before the eggs have a chance to hatch.
