Oh ok... so he's a newbie to your small tank (I read about you're getting a bigger one soon - good
). I say give him some time to calm down himself. Everything should be ok.
I just wanted everyone to know that salt in a freshwater system is a good thing. Freshwater systems in nature do contain (naturally) a small portion of salts. That is why when you add a little bit of salt to your freshwater aquarium your fish tend to do better, although it's not completely necessary to keep healthy fish. It doesn't hurt to put some in, that's all I'm saying. 
Him eating is a good thing by the way. That's a great sign your fishie is good. 
Ok. That's my input again. I'll still be promoting the post for you.
Keep us posted on any changes please.
