I'm glad Draco is eating again, that's always a good sign. If you want to try and get him to eat pellets, you can either soak the pellets in garlic juice or in the juice from thawed frozen bloodworms. That might encourage him to try the pellets. Hehe, I hate it when they decide to be picky.
Hopefully Rosco will also eat soon. If he doesn't show some activity, you may want to scare him out of his mancave just so you can get a good look at him and make sure he hasn't gotten worse.
Your tank may be cloudy because the filter was off while you were doing the medicine; sometimes turning it back on stirs up gunk in the water and it might take a while or a water change to clear it up. It could also be the medicine as it's being filtered out. Either way, if it really concerns you, you can do a small water change and see if that helps.
