I just inherited 2 beardies from a friend who is clueless and has no info on them. As of now i measured them at 5.5" and 6" from head to tail. the 5.5" beardie is shorter because his/her tail seems to have been cut somehow at the end because its stubby.Is it possible to guess age from the size, at this size is it possible to tell there sex? Thanks newbie owner here
