Crab Hitchhiker Id

[drag]

ok i posted some bad pics of a tiny crab that i was tring to get some info on about a year ago. well it grew from about 1/8" of an inch to 1 1/4" inch. took me forever to get him out of the main tank. here the pics any ideas. i know ive seen him eat live brine . other than that i dont know what it eats maybe thats why my hermits slowly dissapear.??

he only comes out at night after the lights have been off for like 1 hour. ive only seen him like 10 times in 2 years. never strayed too far from the live rock.it some time burys itself in the sand.

finally i spoted it in a rock hole on a small rock near the top of the tank, i sanged the rock out and it took 3 day to get him to come out enough to where i could get him. IT WAS A TRICK. but here it is.

Looks like some kind of rock crab, I have one of these that came with some coral, mine is a red rock crab. Never been able to catch him, but he's been no bother, yet..............

No clue what it is .

ATM, it looks like a pretty "peaceful crab". Tiny pinchers like that somewhat suggest a foraging type that slowly pick away at things. I swear i've seen this type before....
