Hi , I have 2 black moor's, one has gone bright orange and he's fine. But the other one has had swimblader I think. He's on his second dose of interpet swimblader treatment. I've done water changes, tests, added more plants because the ammonia was on the verge. haven't fed them for a couple of days now and before I was giving them peas. He was floating upside down, then head down at the bottom. Now when he does swim it's all over the place, very erratic and again with his head down. Not sure what else I can do. Has anyone got any ideas. Thank you.
