Hello from a newbie!

I would leave him in the tank for a week or two without trying to hold him

Haha, oh trust me, there's no holding at this point. He balls up when I open the tank.

Like previously said, let him settle in for two weeks... than you can try to hold him a little if he is more comfortable. I would personally start out with small to medium rats so he doesnt get to stretched out or overly stressed. You said the previous owner couldnt remember when he fed him, so go slow. Once the little guy realizes you are caring for him he may warm up to you. You sound like your on a great start to giving him a happy home. Good Luck, and Thanks for taking him in.
