Hello everyone, I'm new to this site so I'm not exactly sure if I've posted this in the right forum or not, I don't really know what I'm doing, Sorry if this is all wrong.. But anyway, I got a chocolate chip starfish about 2 months ago and he seemed to be doing perfectly fine in my tank. Today, he is upside down, curled up and his whole body is pretty mangled up, it looks like his insides are breaking through his outer ''shell'' on one of his arms, 2 tentacles are moving and a few are attached to a small pebble. and on another arm, there are a few tentacles still moving, but other than that he looks dead. So, whats happening to my starfish and if he is dead what could have caused this? i've checked my ammonia levels, hardness, salinity, nitrite, etc. and everything seems fine, also none of my other fish have ever bothered with the starfish. Do you think, that from the information I've given, that he really is dead?
