Cerith Snail – Cerithium sp. – Small

Cerith Snails (Cerithium sp.) have dark grey to olive green shells and bodies. They are excellent algae eaters and are safe for reef aquariums. Cerith Snails are some of the few species of snails that may eat red algae found in saltwater aquariums, though this is not their first choice of food. Most Cerith Snails grow to about an inch in total shell length although a few species can grow much larger.

Unlike other snails, they are able to maneuver both on rocks and through the substrate, keeping the substrate aerated. A combination of these snails along with some other varieties like Turbo or Margarita Snails are recommended for algae control. Cerith Snails are tidal and may crawl out of uncovered aquariums.
