Lol, that's the spirit! The only ones of the dubia's that don't look like giant roly polys are the adult males. They have wings, don't worry they can't fly or anything.. they will glide or flutter if falling though. You don't need adults anyway. Another thing I should have mentioned, they can be annoying when trying to feed them to your animal on eco earth.. these things like the burrow and will almost immediately burrow when placed on the eco earth, it's really frustrating, lol.
I imagine with a pyxie it won't be bothered if you move it to another container to feed.. my pacmans on the other hand, they don't like being moved before feeding. Needless to say, they rarely eat roaches. I have 100+ dubia's I'm just raising for the heck of it since the only thing that eats them in my tomatos and most of the roaches are too big for them. Rarely does one of my pacmans eat a roach.
