Yesterday I arrived home from work, to get greeted by my Flowerhorn. Settled in and getting ready for a water change. Then I noticed my FH doing some weird things. All of a sudden he was upside down. Was like that for a while. Doesnt look better. When he tries to swim, his tail end goes up like he is going to flip over. Sort of like he is off balanced. If any one knows what this condition is please help. Raised this fish since fry.
