We have never had any problems with the snakes together, they were together before we got them. because the tank is so big its seperated into 3 by degrees if that makes sence. the side there logs are on is 97 with has 100 humidity, the middle fluctuates and am not sure why between 80-90, then the other side there is no lamps or anything so it is much cooler. they have on the hot side, heating pad underneath the bedding, 2 heat emitters, and lighting, the middle has a 2ft wide lighting system that gives off heat as well as a heat emitter and the otherside has nothing. they shed in one piece and a friend of ours who worked at a pet store dealing with snakes only said they are healthy. honestly if you seen them i dont think dominence would be an issue. they slither all around each other sometimes mimicking same actions as one another or just roam around the tank. they have there own logs to sleep under, plenty of bedding to burrow under, pc of tree wood or wht ever it is that you get at petco to climb on, big water bowl to lay in if need be. theres plenty in there so its not that we are not taking care of them but she choose to go on the cooler side of the tank. if i look under the tank i can see she is coiled up under the water bowl. but all i can see in the middle of that is bedding. im hoping our friend will come over tonight, and see whats going on.. if she has not layd eggs i will not worry, mayb she just like the moitsture from the water dish.. will find out soon
