I got him his own tank as he has gotten much worse again on his tail especially, I attached some photos is this still fin rot?, how should I treat the tank from now. Also during the process one of the barbs on his fins got caught on the net and I couldn't get it off so I cut the net he has just been swimming in this corner (I did put a pipe in there) how am I best to get the piece of net off. I probably look really dumb right now but you guys help is much appreciated.
My feeling and suggestion would be to separate the fish. Place the pictus in a qt tank and treat for underlying infection, septicemia. Try some triple sulfa. Keep the water clean. Can add a little salt 1tsp per, once. Best of luck and I hope it pulls through.
