Hey everyone, about 18 days ago I saw my 3 year old hippo was showing ich. About two weeks before that my UV went down and I had to replace it. I immediately pulled all my fish from my 125gal and placed in two separate QT tanks. I began treating with copper power.
The hippo seemed to clear up and then at day 10 in copper he took a turn and now he looks terrible; heavy breathing, lethargic, laying along the tank bottom covered in bumps. All my other fish in the QT were symptom free and now my yellow tang is showing signs of sickness. They are now at day 14 at therapeutic levels (2.5ppm verified with a hanna tester). I dosed prazi last night in the event it was more than ich. The YT now shows light white bumps along his top fin line. Its hard to capture due to my airstone bubbles.
Anyone have any advice on how I should proceed?
The other group of fish in my 2nd QT have no symptoms and look great. They are more copper sensitive; anthias/wrasses/pj cardinals so I was raising the ppm slower in that tank.
