I bought a choco chip starfish two days ago, and I think he's a gonner.
I think my tank either wasn't established well enough or he had a bad breakfast. He was doing fine this morning. There was a small snail next to him on the glass and he was moving towards it. A couple minutes later, the snail was nowhere to be found...no shell; nothing. I'm not completely sure if he ate the snail, shell and all, but it's possible. Not sure if that would harm him, but nonetheless -- he's not looking good now. Poor fellow
