Astrea Snail
The Astraea snail is identified by the sharp conical shell with pronounced ridges circling the shell. The shell is normally a light tan in color unless covered with coralline algae. Astraea remain moderately small. Astraea snails are one of the best herbivores to include in the reef tank. They remain fairly small and so do not have the tendency to knock over stuff like the larger growing turbo snail. Astraea snails are herbivores and spend the day foraging for algae. They are not effective against long hair algae, but help to mow any short algae and keep it under control.
