Description:
Nerite Snails are smallish, less than an inch long, with a very rounded shell.  Shell coloration is variable and often coralline algae covered usually has some type of stripe or spots on a white or tan shell.  The specimen above is mostly covered with green coralline algae, but the natural shell coloration can be seen at the growing edge of the shell.

Natural Environment:
Caribbean intertidal waters

Care:
Reef Suitability:  Nerite snails are good herbivores to include in the reef tank.  They remain fairly small and do not disturb the landscaping.  They are sometimes included as a hitchhiker on live rock. They add to the diversity of the cleanup crew and are used in conjunction with other snails.  They do sometimes have the unfortunate tendency to wander out of the tank due to their intertidal nature.
