Thanks for the input from all! I have her in a 20 gal long, with a dark sarong draped over it to prevent reflection in the glass. She has two hides: one on the cooler end and one on the warmer. She does use them. The water bowl is large enough for her to curl up in. I may move her to a smaller enclosure soon. She was in a 10 gallon at the reptile store and eating fine there. *shrug* I think she will probably shed in the next few days, though. So I'll wait until afterwards to feed.

Cheers
Katherine
