Butterfly 485 Posted July 10, 2017 The short of the question: When can he return to gen pop? I released this fish into my pond a week ago and came back 6 hours later to find him hiding between some rocks with his tail beaten to shreds. I am pretty sure my largest Koi did this which probably spells disaster for the other fish I released in the pond a week prior. This picture is of the immediate aftermath. I put him in a 10g QT with just an air stone, 95-100% water changes per day. 1-2 days later the remaining fine strands had fallen off or were falling off and the tail stump was covered with fuzzy white stuff. I cleaned most of this off with hydrogen peroxide figuring it was an opportunistic bacteria or fungus. A day or so later I got the rest with methylene blue. So this is what it looks like now. So I guess his name is Stump, at least for a while. The fish has been acting well etc. He originally came out of a 75g with his 5 bros/sis. I'd like to put him back in that tank since the pond doesn't seem like an option anymore. When do you think I can put him back? Thanks.
