The only problem with geckos are they can be skidish, drop their tails, and they sleep during the day...up all night. BTS's are great but they need to be worked with and if they did bite as an adult...wow...they certainly can pack a punch. I love the beardie idea. The more you work with them the better they get with handling. I have quite a few different lizards and the chuckwalla and the beardie are by far the greatest with the kids. They can pretty much do anything and the lizards are like..."ok...".
