I keep them in a set up that's pretty much the same as for a collared, with washed playsand, shale for their basking rocks, and temps above 100 in the basking area and 10-15 degrees lower on the other side of the tank. They really like to burrow, and I will often find them under rocks with nothing but their heads sticking out. So be sure to give them plenty of places to burrow, and make sure that they can't shift the rocks around while they're doing it.
As for feeding--I sometimes feed them every day, but if they're adults, they really only need to be fed every two days. I give them whatever I give the collareds (crickets, superworms, wax worms, roaches, etc.), but mine seem to like crickets the best.
Hope that helps,
