They know how to get their human slaves to love them , that's for sure.
They also know how to get their human to do their bidding too.
You are in for a wonderful adventure learning about your little spikey 4 legged scale child. Enjoy , and spend as much time with him / her as you can while he/she's small and goofy and curious.
Just another thing - best to get rid of the current bedding (coco peat ? is fine for bluetongue skinks and waterskinks , but inappropriate for central bearded dragons) , I find hatchlings like your's do very nicely on absorbant paper sheeting (2 or 3 sheets layered taken from the roll everyone has in the pantry.
Makes for very quick and easy cleanup (a little hatchling like you have is going to need feeding with live insects (best feeders are BSFL, blowfly gents, housefly gents, silkworms, crickets, roaches or locusts sized to suit) at least twice per day and will poo just as frequently.
The bedding you have is an impaction risk as some will accidently ingested with the food and if it's not digestible then it can cause blockage and impaction which is going to be very bad for such a young dragon.
I concur regard the red light / night light.
