I know it's a different species but I have a female brook trout the has had issues swimming normally since I planted it as a fingering. It's now 11 months old and 13 to14 inches.
It swims with it's head up and eventually tires out and lays on the bottom for a while. Then it swims with it's head up again. And over and over again. What's crazy is it feeds apparently O.K. because it's growing well and not emaciated. I've tried to capture it with a net when it's laying on the bottom only to have it swim out. I was going to euthanize it with a MS-222 (Finquel) overdose to put it out of it's misery if I could capture it.

The risk I took was calculated, but man am I bad at math!
