Looking to get torts

[frogman]

I am looking to get a pair of torts. I was thinking red/yellow foots or Russians.

I have available for houseing a 4'long 2'wide 2'tall Cage with Sliding glass doors. I will likely remove the doors are there is a 3" lip at the bottom I can raise it if need be but this way they will get plenty of circulation. Heat light at one end and about 1/4 water area (size can be changed it is only a large container.

Just wondering what would thrive in here ? I want a pair not just one but I could settle on one if this is two small. Also they would be able to get out for more room to run around on a regular basis.

Just looking for Ideas and links to good care sheets

Thanks
