Thanks everyone for all your responses!!

I decided to keep him in a 55 gallon I had laying around until I do figure exactly what I am going to do...All I know is this big guys is a handful! I absolutely love him though, such an inquisitive snake. Its funny because Boa's to me have a completely different disposition compared to any other snake. Very "clingy." We also decided to name him Jake.

What size prey do you typically feed an adult male, and how often is a good idea? He gave me a large rat from what it looked like, and that to me seemed too small. Whats the staple size?
