Okay so I've had my first cwd for about 3mon now and just got a new one and have had it since late July. I know it's not a good idea to put two in one enclosure but I did. For the first month or so they seemed fine. They would lay next to each other and I never saw/heard fighting. But I recently saw one of them (the smaller new one) chase the other (older bigger one) and then stopped and started waving?! I also don't know the sex so I don't know if this could be a mating call or aggression? They are currently laying right next to each other with no problems that I can see.
