So, we have a little guy that's been home with us for not quite a week. He's acclamated rather quickly and loves to find your hand in the tank so he can come out and just watch TV with us.

My question is, I know you want to leave them be for some time after they've eaten so they don't get stressed and regurgitate. Knowing how much he loves getting out of his tank, how long should I keep him on "tank-time" to ensure his digestion goes smoothly?
I hate the idea of grounding him longer than necessary, but didn't want to be too eager to let him out again.
(we just fed him here at home for the first time, so hence the question)
