well, first of all, it depends whether your turtle is a male or a female, if its a female and female, your good to go! if its a male and female, then after 5 years or so, the male will start to try mate with the female, it will be showing a ritual where the male puts its claws in front of the head and waves them around. If its a male and male, expect aggressiveness, especially if there was a female and a male before. Good luck!
