No stars and only small blue legged crabs. And where he was hiding for 5 days. I don't think a crab I have can fit. Tiny crevice. Maybe he ripped it getting out or jumped and sliced it on my custom lid. Or a fish. But nobody attacked him that I seen enough to rip a fin clean off. I have a kole,blue tang, 2 clowns, pintail wrasse and swallowtail angel. He's out now. Slight wobble but ate a bunch of food. Nobody is bothering him. Do these fins grow back or is he toast??
