my oranda is driving me bonkers. not sure if he's ill or just a little touched in the head. all my params are great.he has taken to gobbling air at the top of the tank and spitting it out at the bottom. he looks as though he is playing.then he gets buoyant, then he farts bubbles. or he gets clear-ish poop with bubbles encased in it.i attribute the clearish poop to eating aufwuchs (awfuchs) while he was fasting ( may be constipated?). i've just fasted him for about 3 days. now he'll get peas for 3 days. he looks great otherwise. just hate seeing him struggle to swim when he does this. my other oranda is unaffected. my fish are about 8 months old and 4" long, this excludes them from being egg bound. oxygen levels are fine. my other oranda has a much deeper body than this one, and honestly thought the other one might have buoyancy issues first. anyone else experience anything similar?
