So about two weeks ago I lost a PBT and at the end his skin looked like he had dry skin then he died. It was over the span of a week treatment from what I assumed was bacterial due to the fact that he was the only fish visibly affected. So we did a pimafix regimen (took carbon out and did the full week treatment followed by a 25% water change) he looked better midway through treatment but towards the end started looking worse. Then he died. About a week after my purple square anthias died and he had that same dry looking skin the day before he died. Just lost a blenny but never noticed if it had that skin issue. But today one of my engineer gobies has the dry looking sling and I managed to get a video to hopefully show what I mean. I have no clue at this point. Any ideas?
