I have recently moved my two bearded dragons into one terrarium in order to save space and cut down on all the lights and stuff. I suspected that I had a four year old female (Pinky) and a one year old male (Fonz). Now I'm thinking I perhaps have two females because there's been a bit of clawing and biting. Mostly the younger Fonz is biting Pink's tail and climbing on her. Maybe I do have a male and a female. My concern is that I'm possibly mistaken and I have two males. I've checked for the femoral pores and I can't identify any on either lizard which leads me to believe I have females. When I lift their tails I look for two bumps on the underside but along the sides just above the vent, indicating a male or one central bump pretty much at the vent indicating a female. Again I suspect they're both female but this biting behavior is upsetting. Is it just natural establishing dominance or does someone think I might need to separate them again?
