Red Thorny Starfish
Scientific Name: Echinaster echinophorus
Reef Compatibility: No
Minimum Tank Size: 45 gal
Max Size: 12”
Notes: The Red Thorny Starfish or Red Thorny Sea Star requires a large aquarium with ample supplies of live rock. A small specimen will eat algae. As it grows older, however, it is not reef compatible, as it will eat soft corals, sponges, tubeworms, clams, starfish, and other invertebrates. It should not be housed with puffers.
