Looks to me like he's getting beat up, badly. Convict's though small are capable of killing fish much larger than them, especially when they want to breed. Put the convicts back where they came from. And put your O in quarantine, and add some Melafix, and Pimafix. If your tank is not too big, or you don't mind spending alot of money on the meds, just medicate in the current tank.
 
Looks like hole in the head disease to me.
Bad waterquality is often due to the problem.
Keeping your water in pristine condition and feeding a varied diet will help your fish.
Additional Vitamine C couldn't hurt.
How big is your filter and did you test your water?
What are your ammonia-nitrites-nitrates-readings?
How often do you change water and how much?
Getting those test results will help us pinpoint the problem, but I'm pretty sure you wanna start changing 50% of your water on a regular basis, starting now!
Hope you get back to us soon, your fish defenitly needs some help!!!

I have never seen hith that bad before? You can tell it was beaten on, look at the top of the dorsal fin....there's a chunk missing. Though water changes wouldn't hurt. A fish has a better chance of recovering if the water is perfect.
 
also inaddition to all of the other advice, you should try adding salt. to the new water. add like 1-1 1/2 teaspoons of salt per 5 gallons and it should speed up the process.
 
In the picture I see a common pleco... You said he is alone.. ?.. Did you move the pleco too? a Common pleco is certaintly capable of doing that kinda damage to an Oscar and not just the Cons. Time is the only way to heal that, and keep close watch for infection. Regular WC's and maintaining excellent WQ is the best healer. Not to be rude, but If that didn't happen over-night why did you let it get that bad? and it looks like it might be a combo of HITH or HLLE and being beat-up. Hard to tell.
