The snakes all came from the same person just two different dates that are kept together I had not planned on purchasing these 3 at the show and went and bought a 40 breeder untill my rack comes in I tried to purchase a rack at the show and had no luck so I understand I should have seperate etc and qt them but however I got the deal and couldn't pass it up. As far as them both being females yes I seen thm both get popped and the larger female is the one trying to lock with the other female she is obviously not locked and succesful she is just showing sings of trying to breed. The male is a lot smaller than she is and I'm buying another tank after work to house him in as I didn't expect this reaction right away.
