I have had a coral beauty angel for about 2 weeks and the idol for exactly 1 week, my coral beauty got beat up pretty bad when he first got in the tank by my tomani tang. I noticed the white scrape looking things on his face and top fin about 4 days ago, and they have been getting slightly worse every day it looks like. The idol has damage in his dorsal and tail fin for 2 days after he has started hiding in the tomani tangs territory, witch has slowed his appetite I believe, but then I saw the white things on his pectoral fins and am wondering if it is fin rot. It’s only these 2 fish. Pics below
