So I got my dad into tarantulas!

Anyways, he really wants to get one, but his heart is in the desert so he would really like to be able to make a naturalistic desert setup for his T when it's full-grown. I suggested a G. Rosea or an Aphonopelma of some sort (more than likely Moderatum or Bicoloratum) because they're fairly easy in the care department and they're desert dwellers. Are there any others that you would suggest? It would be a look-but-don't-touch pet for the most part, but something docile would always be best in the off chance that we need to handle it for maintenance, etc.

Thanks!
