ive had 2 juvie crested together for a while, and added a third a while later. at the beginning, i was unsure of the sex of each. since i found it to be one male and two females. i had the first pair together since may, and the trio together since july. the first pair seemed to bond pretty well, i never noticed any aggression out of either. they would often sleep during the day curled up with one another. when i introduced the third, she stayed further away from the other two at most times, but seemed to get along just fine with them, no problems. only this past week did i notice any aggression out of any of them, and all of the sudden it seemed like all of them were nipping at each other. i had been on vacation for a week, and i fed them a good number of crickets before i left, we all know they're happy to fatten themselves up. but when i got back and fed them that night, i guess because i had gone about twice as long as i usually did without feeding them, they had become a bit anxious to get a bite to eat, and started getting a lil picky about who was taking all the crickets. one even got jealous because another nabbed a cricket right before her, and snatched half of the cricket out of the others mouth and ate it. it was odd, but i definitely think that since now they're around sub-adulthood things are going to change. they're normally very interactive with each other with no aggression between them as they crawl over one another around the top of the tank.
