I was at my outside pond trying to move a fish, when i caught it it just swam to the surface and started to spin. Not just swim bladder disorder sort of spin, it was rolling and spinning very very fast like it was breakdancing while having a seizure, i took it and put it where i was trying to move it. It kept spinning like crazy than rested on the bottom (its a bottom dwelling fish, so normal) and seemed to ignore my hand completely i could touch it and examine it. It had no obvious physical damage or abnormalities and it was breathing. No injured fins. I let it go and it swam (normally) to a hiding spot. Next day in the hiding place it was very dizzy and aphatic and sleepy. I dont know whats wrong with it. Its not thin or old or wounded. The water is clean and has oxygen
