Description:
Cerith Snails are small, less than an inch long, with a very pointed shell.  Shell coloration is variable and often coralline algae covered.  The body of the snail can be black in color.

Natural Environment:
Caribbean waters

Care:
Reef Suitability:  Cerith snails are good herbivores to include in the reef tank.  They remain very small and will not disturb any of the landscaping.  They are sometimes included as a hitchhiker on live rock. The are not effective against the hair algae monster, but may help with diatoms and cyanobacteria and add to the diversity of the cleanup crew when used with other types of snails.
