Throwing Star Astrea Snail

One of the hardest working algae eating snails, the Throwing Star, or Ninja Star, eats many types of algae including hair algae. Its flattened shell has spikes all around the edges. It stays small at 1 inch which allows it to reach small crevices in the live rock. It should be placed right side up on the sand after acclimation. It is adapted to rocky habitats; if it falls onto its back on the aquarium's sand it is not physically able to flip over and must be assisted. Snails are extremely sensitive to changes in water quality.
