Bought a small box fish yesterday. All seemed fine, he was even feeding straight away. I run a canister filter (empty) for extra circulation and he was swimming up and down in the flow and now it looks like he's ingested some air. He can't orientate his body correctly and is permanently in a tail up nose down position. He's swimming hard all the time trying to correct himself.
Has anyone ever had an experience like this before and can anyone offer a likely prognosis/ advice about how I might help him.
PS.
Because I'm worried he'll get stressed or worse, I've put him in a clear plastic container floating in the main tank so his toxins won't annihilate everything should the worst happen
