I have a large green brittle star and yesterday I noticed some white skin flapping on his back. I assumed it was an abrasion from crawling around the rocks and wasn't concerned. This morning I look at him and he has a hole in the center of his body and it looks like he is disintegrating. His body is 1-3/4" in diameter and the hole is more than half of his body. It looks mushy and brown in the center with white around the edges. He is still moving/alive but I assume not for long. What could have caused this?! I'm worried that it's something that may affect my other fish so I'm gonna pull him out.
