Hello all so i've been QT'ing a Emperor angel and lemon peel angel for about 2 weeks now there in copper currently at about 2.5 ppm checked with hanna copper tester and using copper power. The Emperor is doing great eating anything I throw in the tank like a monster but I have yet to see the lemon peel eat. The lemon peel came in very fat and seems to be losing weight a little. Been trying to feed SF bay angel blend, rods herb blend, formula one carnivore blend, mysis shrimp, brine shrimp. The lemon peel doesn't even look interested at all sometimes will even swim around and not even go near the food. I've tried soaking in garlic no luck. I did fresh water dip this fish when it first came in because it seemed to have flukes and I was correct found a few after the dip. I am not currently treating the flukes because I wanted to do copper first incase velvet or ich suddenly popped up I wanted to be ahead of it. Any advice would be great.
