For the past 3 days my Koran angel hasn’t looked so good. He’s been hanging out in the top corner of the tank, looking like he’s trying to get air. Looks tired, not a lot of energy. His color has faded quite a bit and his body almost has a molt like appearance. I feel like his entire face took on a more translucent - pinkish type color. He’s been in my medicine tank with 2.0 copper safe for 24 hours now. Not eating and just staying in the top corner and breathing fast. Another fish, an orange spotted file fish was added about 17 days ago… the angel didn’t show any symptoms until about day 14 or 15 with the new fish. No other fish seem affected so far. Any ideas?
