spiral swimming in an oscar (help)

[nathan518]

i recently obtained an albino oscar from my brother and it was in less then ideal conditions and when i got it,when ever it goes after feeder fish it just starts to spiral and although its hilarious...its stomach is becoming concave becuz it cant swim to catch its food...i heard it might be corkscrew disiese so if anyone has an idea on a remedy im all ears...thanx

if yu put this post in the general or cichlid forums you might get a proper answer, but to me that fish does not sound good you may have to put it down

May be a swim bladder issue.
