I have a 45 gal. tank, emperor filter, protein skimmer and water qualities are good - had them checked at my LFS yesterday. My clown has not eaten in 3 days. He has been hovering in the corner and his breathing is a bit more rapid than usual. He has had a little bit of white strand coming out of him up under - but I figured that this was him going to the bathroom. I have a black & white false percula also and they have been together now for 2 weeks and have loved each other. My orange and white one (the sick one) was swimming up under him and shimmying alot but now all that has stopped and he won't come out of the corner or eat and his breathing is not great. Any ideas what may be going on?
