Just picked up this small misbar ocellaris but he is swimming extremely strange. He's exerting himself a lot and swimming with his face up at the surface and his tail pointing towards the ground. He occasionally swims horizontally but most of the time he's gasping at the surface and swimming almost straight up. He has eaten a little here and ate vigorously at the pet store yesterday before I brought him home.
Any thoughts on what it might be or how to treat it?
