If you are getting hatchlings this IMHO is one of the best sits available. There is also a lot of pictures of his indoor and outdoor set ups.

I have 4 babies that are in an out door set up for the Summer, but will come in to a 40 gal. breeder tank for the Winter. I keep them inside until they are 3 ro 4 years old. They usually slow down in the Winter and do not need much space. Next Summer they will go out with the big kids. Good luck.
