Congrats on your new BP. A great beginers snake. It's great that you researched everything instead of buying the snake on impulse like most do. As said before you could probably start him on f/t hoppers and or small adult mice. A 29 gallon may be too big. But as long as there's plenty of cover, hide spots, and a large water dish that's easy to find for the little guy, I don't think you should have any problems. Good luck with him, you've got a scaley companion that could last many decades.
