So I ended up setting up a 10 gallon I had handy. I used some sponges and pot scrubbies from my sump to set up the filter. I added 2 teaspoons of Epsom salt to the water. He is gasping pretty hard for air and laying side ways under the plant I put in there. I have pimafix, should I add it in just as an extra precaution for internal parasites?
Was he gasping for air before moving him to the 10? Also I asked before have you seen him defecate? I'd hold off on the Pimafix only because in my experience adding too many meds to the water can cause excess stress on the fish and he's already had to deal with being moved and the Epsom salt addition. I really hope he makes it for you and I hope the thread gets more attention then it has tomorrow so more people can offer up suggestions and help you out.
