I'm trying to find out what causing juvie clowns to swim in circle, then drop dead. A little bit background, I'm breeding perculas right now and has been supplying them to lfs. One of the report that I get from one lfs is that some of these juvies started to swim in cicular pattern in the lfs tank, then finally died. They said it's percula disease, which I've never heard of. All juvies are about 6 months old when I took them to lfs and healthy. Anybody can help me on this? TIA
