There amazing creatures If you can dedicate time to there needs keep one.
I normally keep them in 40g breeder glass. Place egg crate across the entire bottom of a tank. And have a sandbed of 3-4 inches.
To the main question they can smash tank glass. Ive kept mantis shrimp for years. And I know many others who have aswell. Never seen evidence or heard a first hand story of them cracking anything but the bottom pane of glass. Hence the eggcrate.
if it shattered the bottom its because the bottoms of mid sized tanks are tempered glass, if you look at tempered glass with a UV
light you will see the crack in it. if you hit tempered glass on the edge or are able to get within the crack they will shatter. thats really the only way i can see that happening.
as far as the boiling water thing thats a crock of crap. there is to much water around it that dicipates the heat to have it even come close to boiling the water.
like i said i can see them shriking with the velocity but actually generatign the force that a bullet has i don't believe and won't believe it unless i see it crack the side of an aquarium
