hi im Joe and im new to the forums. i thought id join because i just got another crested gecko today and figured being in a place like this would help me, and perhaps enable me to help others with reptiles. so here's my question: I just got a new crested gecko today, I noticed it didnt have any signs of male genitals so i placed it into my 40g tank with my first crested gecko who is a male. Now the male gecko (Jimmy) is starting to attack the new gecko which i assume is female, and i was wondering if this is normal behavior for a male/female crested gecko pair especially since they just got introduced. i know the male/male pairs never work out due to attacking and im getting worried that the new one may turn out to be male despite showing no signs of the male genitals. Its a gecko about 4in long (head-tail) and i figured it would have developed the parts by now if it was male. any help is most appreciated.
