First of all, OFL has been a TREMENDOUS help in answering my many private messages. She has encouraged me to "do what is right" by the fish. 2 1/2 gal tank 78-80 temp. Water lowered to about a gallon so he can reach his food. Water changes twice a week with epsom salts. Feeding only pellets as that's all he can or will eat. He got a little tumor on his side about a month and a half ago. It keeps him at the bottom of his tank at all times. His front little fins work but he can not use his tail. So he sits at the bottom of the tank in a corner or lays up against it on his side. He has not been able to swim in at least a month or more. He can reach his food in the morning and THAT is my dilemma. He still eats and he responds to my voice. But it is breaking my heart seeing him like this. He is a fish and he can not swim. Should I prolong his life as long as he eats? Has anyone out there ever gone through this?
