how to ID Mantis Shrimp

[onlysdad]

Hi,

I'm new to Mantis Shrimp. But two arrived on live rock from Florida Keys. I'm pretty sure they are both smashers, since they click loudly. The one I can see best (because he's in a jar within a 20 gallon tank) overall appears sort of dark green, with brilliant blue front appendages, and some more bluish coloration/markings around his tail. I'm not sure how to tell if eyes are single or double lobed.

I assume someone knowledgable might know the 3 or 4 most likely species this could be. And armed with that info, I could make use of Roys List, or some other source for final ID.

Any help would be appreciated.

Roys List turns out to be easier to use than I had expected, and I think I have my ID: Neogonodactylus curacaoensis.

So, what is a practical way to feed this creature?

And will he not harm a large gastropod (Atlantic Hairy Triton, about 1.5 inches), quarter sized crab (unidentified), or fish?

I assume he would harm dwarf hermit crabs sold as algae control. Right?

Thanks.
