Coral Beauty losing fins

[schristi69]

I have a coral beauty that has taken to hiding in the rock work which is not normal for it. It came out yesterday and I saw that its fins are starting to shred and disappear. There doesn't appear to be anything attacking it. Its color does look a bit more dull/bleached in places but no external sign of disease except for the fin rot. One of my books attributes this to a for of ick, but there are no spots. Any suggestions?

Well, I found what was left of my CB on the back of my Seio PH. I hadn't seen it in 2-3 days. I was treating with Melafix and medicated food. Guess I discovered the problem too late. Looked like the crabs had gotten to part of it and then the current probably pushed it up into the Seio. The cloudiness of the tank is what caught my attention. The Seio was blowing parts of my CB all over the tank. Guess all of the corals got a nice treat.
