Cerith snails (Cerithithium sp.) are easy to care for scavengers who eat diatoms and algae. They are an excellent addition to a reef aquarium, easy to care for and beneficial. They can grow up to 6 inches, though I personally have never seen one that large.

Some varieties of these snails need to go above the water line from time to time...

The picture below is of a Cerith laying eggs on the glass of my refugium.

Another great Pic and write up marlenez!

These are excellent guys to have in the tank. I try to add a few of these to every tank I have, especially to smaller tanks. They make a great addition to any well balanced clean up crew!

The two most common that I know about are Cerithium litertatum and Cerithium altratum. I believe the latter is a 100% herbivore.
