The Cerith Snail, Cerithium sp., is a wonderful scavenger snail that will devour diatoms and algae in the home aquarium. They are best kept in tanks with plenty of live rock, a thick sand bed, and plenty of algae. As nocturnal feeders, the Cerith Snail is one of the most popular snails for their algae-eating and sand-sifting ability. Ceriths require almost no care and provide a nice benefit to any aquarium tank making them a no-risk addition.
These snails are great! Cleaning up my brown diatom algae
Happy with the purchase. They are doing well in my 75 gallon tank.
