I have a few kuhli loaches in my 29 gallon. The others are doing well, eating, growing, etc. But one seems to have a deformity of sorts. Instead of swimming at the bottom he sort of just curls up and squirms around. I haven’t noticed any growth but it seems he has been eating since he’s lasted around two months now. I’m not sure if I should leave him be or maybe euthanize him. Anything I can do for him? Anyone seen this before? The other fish don’t pick on him or anything so no worries there. No further concerns, water quality is pristine, just never seen something like this before. He was like this since I first got him. Mind the blue-green algae in the photo, I’ve got a Cyanobacteria bloom at the moment. But that’s for another thread.
