The Astraea Snail is also called the Astraea Star Snail, or Astraea Conehead Snail. It is pyramidal in shape; some may have projections on the shell which give them a star-like outline.

The Astraea Snail will do well in an aquarium if provided with ample hiding places and sufficient room to roam. An aquarium with live rock is preferable so that it can graze on the algae. It will also graze on algae on the side of the tank. In addition, it eats cyanobacteria and diatoms. Do not place the Astraea Snail in an aquarium with hermit crabs. If it falls, it is often unable to right itself, and will need the aquarist to place it upright, again. It is sensitive to high levels of copper-based medications and will not tolerate high nitrate levels.

The diet may be supplemented with blanched spinach or lettuce and vegetable-based tablet foods.
