Ive had this guy for about 8 months and he has always looked like this in my tank, but he didn't look like this when i bought him. Any idea what is going on? He is a normal healthy otto other than his color

I suspect he had a stress-triggered hypomelanism rather than true leucism. I've heard of it happening in birds, but I haven't read any scientific journals on it happening with fish--but it sounds exactly like what happened to your oto.

He may or may not have a genetic predisposition to cause it to trigger with stress.

I would imagine it's permanent. With birds, sometimes it's permanent and other times it goes away as they lose the stress and molt--they regrow feathers of their original color. My suspicion is that if he's been like this for 8 months that he's going to stay white.
