Thanks! I didn't know about neons and salt, so I'm glad I didn't try salting the 10 gallon!
At first I did try floating his cup in the aquarium, but he kept trying to swim through the clear plastic so I moved him. However, I don't use any air conditioning in my apartment so the temperature of the water in both tanks stays at 81. I've been salting the water using a little less than the recommended dosage and his dorsal fin is almost completely healed. His caudal fin is still quite shredded though, so it might be a while before that heals.
I'd post some pictures, but my camera doesn't seem to want to focus on him unless there's a dark background, and he's very active. I'll post some pictures as soon as I can though!
