Hello and welcome. I house them identical to russian tortoises. Here is a care sheet to tell you all you need to do to keep them healthy and happy: http://www.tortoiseforum.org/thread-80698.html
Are you in CA? I hope you didn't pay too much for them. It's illegal to sell them. Free, yes. For money, no.
Not sure what can be done about it now though...
Read that care sheet then come back with your questions. Happy learning!
I'm thinking that this is Rachael88's sister, no? So you all can read the info we've been giving Rachael about the two desert tortoise hatchlings here:
