I have had good luck with Stressguard by Seachem. It coats the fish and reduces stress. It also contains antimicrobial agents to prevent infection, unlike other stress treatments. It won't clog up your filter either. I use it alone, or in tandem with Paragard if I see signs of illness / infection.
Poor guy. Hopefully he's on the mend soon.
