first australia(beardies) and africa(uros) are seperated by only a few miles, and climate changes. they need different care. also, these animals can be aggressive towards other males, and you never know the reaction theyll have. stress is another reason. parasites, feeding, bullying, want me to continue? i have no intention to be mean, but it isnt reccomended at all. i dont mix any animals, and the only ones id trust are animals from the same area, which are the same size, temperment, and have the same diet, but i wouldnt reccomend it either. i hope that helps you
