Team, i imported this angel from Shri lanka several weeks ago. roughly 4 weeks. He was in QT for 3+ weeks, we freshwater dipped upon arrival in copper power at 2.5ppm with 100% water changes every 3 days, them Prazi and metro for internal parasites for several days. the tank is roughly 4 months old, it is FOWLR until it matures enough for SPS. this fish is the only one showing signes of this. they have not been their before this morning i dont believe. I treated the entire tank with Prazi after i moved everything over 4 weeks ago from QT. did a 80% water change. I dosed Ffluconazole yesterday for a GHA outbreak and noticed this. the fish eats like a pig and swims no flashing of any kind. they do not seem to be exterior on the fish. the skin looks smooth over the spots. this is a macro shot using iphone 14 pro max.
