Got a new yellow clown goby over the weekend. Today I found him floating sideway on top of the tank, thought he was dead but when I poked him he started swimming around and looked ok except for what looked like an air bubble in his stomach. His stomach looks a bit distended and when he would stop swimming down he'd float up like a balloon.
this normal? do I need to give him a fish size dose of gas-x?
