Hi, I have a 20 gal tank containing 2 ryukin goldfish. One has begun floating upside down at the top of the tank. He seems to be doing this during the time when he is normally inactive, and the other goldfish is inactive as well. I have read that this can be a swim bladder problem or constipation, but he seems to do this purposely. He swims to the corner of the tank when the light is off and rolls over. Always in the same spot, where the current does not push him around. At first, I thought he was dead, but i've gotten used to the behavior. When i walk up to the glass, he rolls back over and begins to swim around. When the light is on, he is very active and he is eating normally. I was under the impression that if it was a swim bladder problem, it would be difficult to flip him back over; and i am still seeing bowel movements from this fish. Is this a real problem, or is it possible that he just likes to rest that way?
I appreciate any input.
