As much as I have NEVER seen a fish live that long after losing equilibrium, I'd start by feeding him Epsom salt soaked food...I honestly would not have a clue where else to begin with treatment for this...
Sorry, I didn't see your reply before posting that second bit. It was meant as an afterthought to my first post. I'm using a phone with terrible reception at the moment. Completely agree that Epsom salts are the best choice for treatment. If it doesn't work, it is likely because the issue here is genetic in nature and there likely isn't a solution.oh no I know that haha, I meant if this was an issue in the swim bladder or intestinal blockage or something along those lines, I love using Epsom salts but I know they don't cure DNA issues haha. I'm interested to see updates for this...I've never seen a fish go belly up that long/often and last more than a week.

If it has been 6 months then I doubt this is blockage or swim bladder. A blockage would've built up too much and it would've died already. If it was a swim bladder problem I would assume that after being like that for a week it's intestines would've been messed up (however being upside down for 6 months should've had some serious damage done already). I don't think the salt can hurt, but if it's been like this for a while I'm not sure there's any medicine or treatments that can help. I think it's a genetic problem or even something caused him to be like this. Maybe he got scared and from being a SB he just hit a piece of decor or tank wall and he got messed up.
