Help with my Jurapari

[rvm]

After an atatck from my severum, my Jurapari looked a little beaten up, his fins were torn and he was missing scales with a pretty nasty wound on his side. I dosed with Melafix and he seemed OK for a couple of days. A bit listless and inactive but not geting anyworse (I separated the severum as well).
Anyway, last night I noticed his eyes had sunk, so I got worried, and this morning it looks like my fears were justified as he is now upside down and not really aware of what is going on.
Is there anything I can do to help him, or is it too far gone to do any good now?

the only thing I can think of is to do regular water changes and see if that helps.
Sorry but I have have a feeling that it maybe too late

It was too late, he died on Wednesday. I put a post in chit chat. I was absolutely gutted!!!
Thanks for the reply though mate!
