Hi, and no. Beardies are territorial and only come together to mate.
As you can see that guy just wants more money from you, and doesn't care about what hes selling just that it sells alot of them.
Please go elsewhere to get your beardies, or go online to find a great breeder. I'm not sure where you are located but I'm guessing its america somewhere, so you have alot of options.
What else did the man say for you to do? Because it was probably wrong aswell
Please feel free to ask us on anything you are unsure about, there's a wealth of information here from lighting, and what to avoid with lights, all the way to if the poos are healthy!
So please do not hesitate, it is for the wellbeing of your beardie, it relies on your knowledge and care to thrive, so make sure you have the right info!
