Is this a Mantis Shrimp?

[dareefguy]

I plumbed in a little acrylic 5 gallon into my system for my mantis shrimps new home. Catching him was more difficult for me. I ended up getting the rock he lived in out of my tank and actually had to drill a hole in the back of it with a chisle to get him out.

For some of the larger smasher mantis, estimated that the impact blow equals that of a bullet from a 22-caliber gun- comparable to a compressed air jack hammer! No wonder that there are reports about mantis having smashed thick aquarium windows. "The Modern Reef Aquarium Fossa, Nilsen"
