About the glass breakage thing. When I was looking at the "Lurker" website mentioned by one of our other members, there is a recorded event at a public aquarium. They mention the aquarium, the name of the mantis, and state that it broke the 1/4" thick glass that it was enclosed in. I would guess that thicker glass would be safe, but that's just me guessing. If anyone isn't convinced, I guess I could go back and find the report and paste it.
