I was hand feeding my spiney puffer and glanced away. He got hold of me rather than the food and in instant reaction I jerked my hand out of the water - but he was attached and he plopped out on the rug. The fall didn't injure him but he tried to puff and sucked air. Now he has a large air bubble caught in his system and he floats. He can get down but only with expending a lot of energy and he is looking very fatigued. I tried chasing him till he puffed normally in the tank but that didn't dislodge the bubble. Will this correct itself or will it kill him? I sound silly but I'm attached to this little "water dog".
