Here are some images of Stomatopods (mantis shrimp):

Here are some commensal crab pages:

Acropora photo from J&L (ours is brown in colour, but looks like these):

So, from the above photos, our critter looks somewhat like the mantis shrimp in that it has a long slender body, but unlike the mantis because it has long extended front legs with long claws.

On the other hand, it could be a variety of commensal crabs, though they seem to have rounder bodies than the sleek long body of what we could see of our guy, who looks like he's less than an inch to about an inch long. Pretty hard to see his whole body in amongst the acro branches.

I'll study the photos and our hitchhiker more closely and keep an eye out for more disapperaing fish. The fish that was lost was one that spent time hiding in holes in the live rock, so a mantis shrimp might be what we have

If it is a mantis, we'll have to build a trap to catch it

Hmm

Thanks for your input, Deb and ranz.
