I recently purchased some live rock for my tank and just discovered today what appears to be two different brittle starfish living inside one piece of rock. At first I thought they were stuck inside the rock because all you saw was their arms sticking out of small holes (I was thinking that the holes were too small for them to get out of the rock. I was wondering if I should crack the rock to release them). But, after doing some reading it seems that they hide in rock and are mostly nocturnal (I guess he can get out if he wants?). Is there anything I should do or know about them to keep them healthy?
