I finally put the live rock that was curing in a tub into my tank. When I was pouring the water that the rock was in into my bathtub, I found a starfish. It's black with white spots and is black in the middle. (identification?) Well, I put it into my tank on a rock yesterday, and now I cant find it. When I came home there were hermit crabs where I left it. Could the hermits or a fish have eaten it? It's small, fit on the tip of my finger. Also, there is some tentacle like thing that comes out of holes in the rock, any idea on what this is? Any info would be helpful. (By the way, new to this whole forum thing so I'm not sure if I should have put this in an old post or started a new one. Sorry for my ignorance)
