New Owner with LOTS of questions!

The tiles are a great idea! Thanks, guess we'll wait on the sand then. He has his beard starting to really show now. My other son is really wanting us to get him a "friend" but I know we'll need to know his sex first. Does anyone know the rule about if a female can live with a male, etc.?

Some will recommend keeping them separate, but I have found that as a rule, a male and female, or 2 females (better, of course, then there is not the stress of unwanted breeding) can live together just fine, provided that they are of the SAME size, and have plenty of room. 2 males may live together fine as younguns, but will NOT once they reach maturity.
That said, Beardies are just like us humans, as there can always be the case of 2 animals whose personalities just don't mesh, and they simply will not like each other or get along, for no apparent reason.

You can see if the show allows you to bring your own animals, and if so take Giz with you and have him/her sexed. Then you'll know what to get. Sounds like you'd be ok with getting a female either way. The only worry is you don't want a female to get pregnant before they are of a certain weight (350 grams or so) because they can become eggbound.
I like the tile idea too... need to check that out.
