Spiny Brittle Stars
From Microcosm Aquarium Explorer
[edit] Overview
These brittle stars need to be well nourished. In underfed tanks, they will not receive sufficient food, the arm tips will start to “erode,” and eventually they will starve to death.
They have a small central disc; the five arms look too big for the central disc. Arms have large, narrow, sharp spines on their sides. Typically gray, tan or mottled combinations of gray, tan, brown and black.
