Rainbow ricorida mushroom issues

[bunkbunk]

I have had a rainbow ricordia mushroom in my tank for about a month now and it was doing well up untill a few days ago. It looks as if the edges of the mushroom are starting to dissapear. Does the Yuma perform a feat such as that when it is starting to split or move itself........ Or is something eating it. I have a Purple Tang, Japanees Swallow tail angle, 2 Ventrilis Anthis , 2 Mandrins, Blenney, and 2 percula clowns. Various hermit crabs,Peppermint Shrimp, 2 cleaner shrimp and snails....
I just moved the Ricordia into the refugium any thoughts?

Hmmmmm, they usually look pretty good when splitting unless it's due to stress. Rics can waste away if they're unhappy in a spot though. I have one that got shaded from another coral and it just withered away in the following months while the rest looked beautiful. It never really closed up or deflated, it just got smaller as the weeks went by until it disappeared completely. If you have weak light in the 'fuge it might not help at all. I'd put it out in a little better lighting and flow in the display and see if it does better in a different location. Those fish really aren't a ric threat, so I wouldn't worry about them being the culprit.

Ok check. Just FYI I have three other kinds of Ricordia in the same location and they are doing fine. I have a 18 watt 10K/Actinic PC light in the Fuge. The ricordia looks as if it is just disolving around the edges in certain places. I have hand feed it some brine shrimp with spirulina and it's eating.....This is wierd. I have many other corals that are much more sensitive to change and everything is fine. Water parameters are as good as I can keep them. Could there be some sort of Bacteria that only effects Rics......
