Very true. This is what I love about reef aruariums.

shells don't necessarily have to be broken by a mantis. If it can, a mantis will just pull the snail/hermit out of the shell without smashing anything. It just means less effort for the mantis. I wouldn't rule a mantis out, but wouldn't jump to conclusions either until you've gotten a good look at it.
