Unfortunately, due to where the fish jumped, there was a brief lapse in time before the fish could be returned to the tank. Upon being returned to the tank, a majority of the skin peeled. Over 85% to 90% of its tail fell off, and the entire middle third of its right side fin fell off as well. I was advised by the pet store to add Melafix to the water, in addition to changing 25%. This isn’t working. And where the fish would normally be very aggressive in eating live feeder fish, he swims away from them. If this isn’t the case, he remains in the corner of the tank, floating awkwardly, even with some of its body out of the water. I don’t know what to do.
