I don't personally keep bearded dragons, but from what I do know is that some of them like attention and being held (especially on the shoulder!) And they are extremely smart and need good enrichment! So maybe try getting them some toys directed specifically towards beardies. They do need exercise so if that's you letting them run around for a bit or even taking them on a little stroll when temperatures are okay then that would be nice!! Apartments are usually a smaller space, so it may be easier to keep an eye on them but just make sure there aren't any holes where they can get stuck and you can't reach them. Again, I don't keep them and I certainly don't know for 100% I've just seen that that is something in general that is done with them. (If you already know this, my apologies!)
