im really worried, but my pet goldfish buttons keeps swimming into the sde of the bowl repeatedly. he also sometimes swims upside down with his left gill in the air....is this normal behaviour?is there anyone like a specialist whocould help me with this problem?i miss buttons...hes my best friend.
sounds like swim bladder problem you can get chemicals or buy a little blood worm frozen or alive this will push the air from his bladder he could also have dropsy which again is the fish bloating with air
