upside down goldfish...

[numb-skull]

A bit back one of my goldfish started floating upside down, and kept rising to the top of his tank. Although it seemed physically ok, it didn't seem too impressed with the situation... after a fair bit of surfing, and failed remedies, I came across one that recommended feeding it small segments of frozen peas. I was pretty sceptical, but then 30mins or so after eating the pea pieces he seemed to have sorted himself out. About a week or so later the same thing happened, and again was remedied with the peas...

Obviously this strange cure works, and I now give him a broken up pea every few days to stop it reoccuring... Is this ok to do? - he certainly seems to have no side effects, but could it be masking any other issues? thansk!

What are you feeding them beforehand? is that they gulp all the flake really greedily, taking in a lot of air?

What happened to cause the 'up-side-down' situation?
