Hello,
I think some people do house beardies together, but it is absolutely NOT advised.
They may tolerate eachother at a young age but as they grow there could be dominating, intimidating and over mating, which can stress out a beardie and could lead to violence.
I understand that dragons may appear genial towards one and other one day, and the next day there has been an incident.
I have a rescued dragon who had two of her claws bitten off by other lizards she was housed with.
It is, on the whole, a big risk to take with your little ones health and wellbeing.
So if you possibly can, get them into seperate tanks as they grow.
