For the last 2 days my flowerhorn‘s has been floating backside up in the tank. I think he has bloat and hot sure what to do. He just stays in one spot kind of stuck to the filter. His stomach is bloated. Yesterday I did 2 Epson salt bath for him, each for 5 minutes. One in the morning and the other later at night. After each salt bath bath and I would softly massage his stomach to push all the fluid out of his stomach. He would act normal for. Awhile and then go back to floating backside up. He doesnt move at all and his stomach fills up again after a few hours. He is very lethargic. Doesn’t move at all until I come near the tank where he thinks I’m going to feed him. I haven’t fed him in 3 days. He will act like normal but then go back to the corner and float backside up and just sit there. The tank is a 75 gallon tank. 0 ammonia and 0 nitrites with 20 nitrite. He is about 8 inches long. The other flowerhorn is acting fine and swims perfectly. He is about 4 inches long. 3 days ago I gave him 4 pellets that were soaked in a epson solution . Not sure what to do at this point. I’ve read that at this point I should just take him out and euthanize him as he is probably going to pass. The only thing I could think of that might have caused this is I bought 16 Bueno Aires tetras as dither fish and within 3 days he ate them. I wanted to check with this group first before making that decision. Please help and tell me what you think could be wrong with the fish. Thanks. The last picture is him thinking I’m going to feed him.
