Thanks guys!
I appreciate your concern but I've had these guys for a few years now. They get along great. To be honest they've been together in a 12x12x18 Exo-terra before this upgrade and have been perfectly fine. The male is very easy-going and they are all fat and happy.
They get one Food, one Water, and one Calcium dish, they share nicely.
They make amazing offspring!
P.S. Obviously I will make changes if I see any stress. But like I said, all has been easy going thus far. The male is separated half of the year and the females naturally stop laying eggs on their own. I admit I have been lucky with this group.
