Purchased 2 fish a week ago. A dwarf angel and a Pearlscale Butterfly. They are in a 20 gal quaratine tank. Both were doing well and, with regular water changes, everything was testing very well. Went down this morning, and both fish were swimming fine. Did a water change using 10 gallons from my DT. Went down this afternoon, and still fine. Went down tonight to feed them (about 9 hours after water change), and the dwarf angel was sitting still on the bottom. He is breathing, and when I move him, he moves, but is not very responsive. I did a the basic range of tests, and everything is good (0 nitrate, 0 nitrite, 0 ammonia, 7.8 PH). The butterfly is doing fine. I fed them and the butterfly ate like crazy. I ended up picking up the angel and hand feeding him, and he did take a couple of bites out of my hand. When I let him go he went to the top and was biting at some bubbles, but then slowly floated back down to the bottom and laid on his side. I do have a bubbler in the tank, so I don't think it is an oxygen issue.
Any suggestions? He was looking really good up until now! No outward signs of any illness. He has been pretty shy, so I haven't actually seen him eat, but he seemed healthy for the last 2 weeks otherwise.
