x3 on sand being a no-no. In fact, it's a HUGE no-no in the reptile world, especially with Beardies. It causes impaction, which can (and usually is) fatal to reptiles.

Try newspaper, tiles, or a Reptile Carpet. We have used all 3, love em all, but currently, Aaliyah has tiles which have the best visual value.

LLLReptile has pretty good caresheets, but I would read as many as I could to verify information and get more opinions. Also, a book always comes in handy.

A Beardie Nutrition bible is: http://www.beautifuldragons.com/Nutrition.html (There is not ONE person I know who's serious about Beardie care that doesn't reference this site.)

Good luck on your Beardie. They're somewhat high maintenance pets, but very rewarding.
