Koi Swim Bladder Problems?

Carol B asked: Just started to feed my outdoor pond koi carp – not eating yet, however one seems to have Swim Bladder – (he is sitting on the bottom upside) but swims off if i try to move him. I have read about giving thawed out frozen peas – does this work? Suggestions please…. [...]
