I am sure you know if you have been interested in Mantis shrimp for a while, but you definitely need to get a bigger/stronger tank if you want to keep him, the club ones can pretty easily break the thinner glass on smaller tanks.
I was looking into getting one, but after all the troubles my Crayfish caused me in my freashwater tank, I didn't want to get his cousin that would do the same, plus break my tank lol.
If you have looked into it minimum tank size and glass thickness please let me know. I have been thinking of getting another tank down the road and would love to get the thing that got me interested in saltwater tanks in the first place! Just want to make sure I don't end up with a bunch of water on the floor of my second story appartment lol.
