I have two butterfly goldfish who prefer to float upside down evry day and night at the top of the aquarium this has been going on for seven months so it's not an illness but seems to be related to swallowing air bubbles feeding or not...I have changed out food and it has made no difference...I am getting ready to send my other fish out to the pond and it looks like these two will have to stay inside for the summer otherwise they'll be fish food for some other critter...any ideas? anyone else with this abnormality? Thanks
