Just a few questions:
 
Sounds to me like it has been in a fight and lost 

 
Have you any idea of what sex your albino cory's are?
 
Shouldn't both your species of cory's be a minimum of 6? (others will advise you better than I on that one)
 
Any chance of isolating him in a QT to try and give him a chance?
 
 
Edit: To take out silly question..

Yeah that's what i had thought...
I have no idea what the sex are for any of them I'm afraid
I bought them as a 4 because it was 4 for £10 and 3 for £21 for my albinos and pandas respectively that is the only reasoning to the numbers
I have a small shrimp tank I could put him in but the shrimps are so small he may eat them!

Cory's aren't known for eating other tank inhabitants. Give it a try so he is less stressed and has a chance to heal. Keep a watch for any aggression from your other fish to see if you can find out who the culprit may have been... although I don't think any of the fish you mentioned are usually that aggresive.

Ok I'll give it a shot. See if he's any better.

Youre right, I have never had any problems with aggression, the worst aggression I have ever seen is at feeding time and that's only like boisterous behaviour to get some food etc.

Hey guys just an update.

I've put him in quarantine and he's already acting more normal by feeding off the bottom and generally going for air a lot less.

Maybe he's less stressed now and hopefully he will recover quicker in this environment
