I think your LFS
was correct in the malnutrition. I believe that their diet is more phytoplankton based. As in..copepods and worms, also algae. I didn't think that this particular starfish ate coral, but again, could be wrong. Never really see it in tanks or sold much, probably because of the difficulty to keep. If you can, I'd consider returning it. If you can't...I'd atleast supplement with something like DT's phytoplankton, oyster eggs, or copepods.
