Hi. Everything was going just great till a few days ago. I was treating my tank from ich and on the last day of treatement I noticed a bruise on one of my weather loaches. At first I thought he just got into fight with some other fish or he hit the wall from jumping all over the place (like they always do before rain). The next day I noticed that top fin was split and the "bruised" part became red. On top of that i noticed cotton wool like patch just obove his eyes. I went to a pet shop and bought: http://tinyurl.com/pbj92on
I dosed it as per instructions and its been 2nd day after treatment but improvement is marginal and insturctions say I can only use this product every 7 days. He is mainly hiding and not eating as much. Is there anything else I can do for him?
