I don't know that I could euthanize a sick fish. Maybe if it was injured to the point that I knew it was hopeless and I coould definitely tell it was in serious pain I would but probably not for a disease. I'd just try to isolate it and make it as comfortable as possible.Y2J said:I hate the euthanasia thread and dont believe anyone has the right to end a fishes life if its in pain or not. If it asked then maybe but they will have to learn to talk first. If we got cancer or something which would give us a few months to live, i for one would like these months to live as much as possible and then die. What i wouldnt like is for someone to make the decision for me. Just because have a level of pain to deal with doesnt mean living still isnt worthwhile.
