This is my first Bearded Dragon and i just picked it up this morning and its been exploring its tank all day. It's probably about 4-6 inches long not counting tail. I have the UV light a basking bulb and a 30 gall tank (36x18x12). It has a Calcium sand substrate in it that i got at the pet store. It seems to be really active and everything but it just started digging about an hour ago. It first starting digging in the sand underneath one of the structures in his tank and I thought he was chasing a cricket. Once i moved the fake-log thing he/she started doing it near its water. I looked online and it said that females do it when their tryin to lay eggs but i just got this thing and I believe the guy at the store told me it was a male because of some color spots on its underside. Im not worried about it either way (male/female), i'm just curious why its digging? Should I get more substrate so it has more room to dig? Or just leave it and eventually it'll get the idea that its not making any progress.
