That is kind of a big tank for a baby but it depends on the personality of the dragon. Some are real nervous as babies and some are very mellow. make sure he has a couple of hides and a branch. If he feels alittle vulnerable he will chill in his hide or climb up on a branch. The problem with big tanks with alot of stuff in it is the crickets have too many places to hide so the beardie cant find or catch them, so take the stuff out when you feed so you know how well he's eating
