Having seen some lovely baby bearded dragons at my reptile store, and i have decided to buy two! What size viv is needed for two baby beardies, then two adults? Also,is it better to buy one, wait untill it grows a bit, then get another one? When can beardies be sexed, so i know i have two females and not two male or male/female beardies, as i dont know enough or want to breed them. Thanksfor any help!
