Thanks, Roy. I will research the species. It's odd that I would have a florida mantis in my tank with only pacific live rock (mostly Uaniva with a bit of Tonga). I suppose it *might* have come in on a small rock that I bought for the mushrooms that were attached, but there are no burrows or holes large enough for it. Also, I suppose it's possible a florida manits could get into pacific rock if the live rock were in a holding tub together at some time.
I will try, however unlikely, to get some better pictures. In the meantime, if anyone would like to second this ID all thoughts or comments are appreciated.
What is this guy going to eat?!
