I've had my RBTA for a few years now I think, and it has always been very happy. Even today, it was looking better than ever. But now, it looks like its on its death bed! It's mouth has gotten huge and whiteish. It looks kind of like a dying soft coral. Its tentacles have gotten really small and flat. All my other critters are fine and all of the chemicals seem to be fine as well. My clownfish have laid eggs by it for the first time, but they did that last weak and so I don't think this is the problem. Any ideas of what could be happening? It looks like it spit something back up through its mouth. The fish were feasting on something from it, I think it was part of some fish I fed it. Could it just have an upset stomach? What can I do?
