I posted about this problem a little while back.

Some people told me it was old age, but I do not think that anymore. He is now swimming completely verticle with his mouth touching the surface. He is also doing rolls, sitting on his side on the the bottom, and swimming in all sorts of wierd positions. I am now feering for his life. My water chemistry is fine. He is also still not eating. (He won't even touch live foods.) Is there anything I can do!? Please help.

Sorry but they do all that when they are dieing, it's sad.

I'm afraid Wilder is almost certainly right, when fish reach that state the best thing for them is to euthanise them and end their suffering
