Well my bearded now is about 9 inches long. He is in a 20long right now, and is growing like a weed. I picked him up a PVC enclosure at Repticon that is 4' long X2' wide X 18" tall. I want to move him into his bigger enclosure, but would he be freaked out by the space? I'm going to make his new enclosure identical to his original (same basking rock, logs, etc.). Can i move him in there now? Or wait a little longer?
