i keep my two beardeds together which ive done since i bought them in august but im concerned because the larger of the two has been shaking his tail alot lately whether it be in the cage or when i take him out. im not sure whether i have males or females yet i think their still too young but does anyone know if this constant tail shaking can be a sign of sexual desire?....he/she also rubs his head almost violently against the floor and his tree bark sometimes. can anyone help me?
