Has anyone ever had their mantis interact with a millipede before? Do they eat/hunt them? I have a 12x12x18 vivarium and I was musing the idea that it might be cool do get a couple of small millipedes to coexist/live in the bottom of the tank but I'm not sure if they would just get eaten or not. I usually have a couple of flies in the tank at all times so the mantis will always have prey available.
