what do you mean by gravid?? and they have been housed together for about 2 years in a 125 gallon tank. they always use to be coiled up together. we actually got them from someone who housed them together in a smaller tank but she was still a baby the male is prolly about a yr older than her. the side shes on is prolly about 60-65. n no to be honest i was petrified of snakes when i got them, and so uh yea knowin she could strike if there is eggs not a idea that has come to mind. i have a friend comming over who will check tomorro hopefully i will find out soon.
