For my Birthday, my son took me to LFS, were I got more LR and a chocolate star fish. First addition in over 2 years. There were 3 in the tank and 2of them looked fine the guy of course grabbed the one that was stuck to the front of the glass which I didn't see. When getting home I noticed that one of the chips were white not black. Acclimated him added to the tank (came from a fish-less system) stared roaming the tank. The next day put him on a half shell clam he almost ate it all, then my butterflies scared it off. Later that evening noticed that the white spot was gone and was replaced by a hole. The next day found him with half of it leg had been eaten and the butterflies wouldn't leave it a alone. Figuring moving or leaving it was going to die either way. Next morning it was dead. So again I was reminded when buying anything always look over your purchase.
