Can anyone help i've had two horsfield torts for a couple of years each are now several years old. I have always believed both to be males,as to me both look like they have thick long tails,caried to one side.however one always assumes role of a male and continually mates the other tort.he always performs the mating ritual and the other never assumes this male role,it is always less dominant and if you like takes the female role. Have i sexed my torts wrong(at least one of them!) could the dominant one be a female,or could they still both be males?? please help!!!!
