Overview

Don't let the Cerith Snail's small 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. The Cerith Snail is extremely difficult to breed in captivity. Not only is determining the sexes difficult, but the water parameters required to do so are unknown.

Like other invertebrates, the Cerith Snail is sensitive to high nitrate levels and copper based medications. It also requires a gradual acclimation process, preferably the drip acclimation method, since it is sensitive to even minute changes in water parameters.

Approximate Purchase Size: 1/2" to 1"

Customer Testimonials

Jackie E. Charleston , SC



I ordered several of these fellows and the very first day they were busy cleaning the tank and eating algae. They're very lively and hardworking!
David S Coats , NC
My Cerith snails frequently mate and lay eggs in a stringy, curving mass on the inside front and side glass of my aquarium. However, filtration and other tank inhabitants quickly consume the young. These snails are excellent for sifting through sand and gravel beds.
Eric P Kempner , TX
A well balanced snail that helps sift sand, remove excess detritus and consumes algae. I pair these with Astraea and Nessarius snails as a large part of my cleanup crew.
