eat everything, snails, hermits, fish (if they can catch it) corals, etc.
are you sure you didn't just find a molt?

Wow, guess he really isnt one I want in the tank.
If it was a molt it was the most lifelike one I have ever seen, had some weight to it, and didnt seem to fragile, it couldnt have been much bigger than 1/2 inch accross.

mostlikely it's just a molt if so small and out in the open... which means you probably have a 3/4-1" crab now.
i thought i lost my teddy bear in my fuge, pulled out the molt, even saw what looked like meat inside the shell.
nope, teddy bear still alive. the molts stay together quite well.

we had a tiny little crab in our sump that we thought was dead, it was just a molt - those little skins can be quite lifelike

I had a little crab that looked a lot like that. It would eat food that I gave it. Otherwise, I saw it munching on the coralline algae. I watched him do it! Left tiny little verticle lines in his wake, lol.
I liked him he was cute. He did however have red eyes. If you ever see yours, assuming that is a molt, and if his eyes are red, then I'd keep him.

red eyes mean it is a nocturnal predator...
look in the invert section, reefkprz has a thread about a crab he has, where someone linked a crab identification page.
this is a type of xanthid (rock) crab, which are not reef safe/fish safe

Rearrange my tank a little the other day and caught one that looks just like that one. Into the middle rear chamber (my fuge) he went.

Just wanted to update this and ask for HELP!
My sixline I had for a strangely short time went missing VERY shortly after this, like just gone of the radar, looked everywhere never found him.
Fast forward to last night, feeding time. I was feeding the clowns and seen something move on the rockwork out of the corner of my eye. After feeding I check out the general area, and there he was, hidden quite well. THIS WAS JUST A MOLT. And he is about twice as big as the molt was. I tried to get pictures but he was to deep in the rocks to get my d40 to correctly focus on him, so I gave up for the night hoping to find him.
Tonight - didnt see him at feeding time, so I waited till about a half hour past lights out, and whipped out the laser piointer, works quite well and it seems as if it doesnt disturb anything, and I found the little ---- where he was yesterday, I put my laser pointer in flashlight mode and looked at him, he was MEAN looking, much darker in color than the molt with bright RED eyes. I quickly grabbed the smallest net I had and tried to get him but failed and eventually gave up.
While crusing around the tak with the lights out checking out all the other neat stuff that only comes out at night I kept going back to where I seen the crab, and again out of the corner of my eye I seen something move, on the big rock next to the one with the evil crab living in it. I looked closer, and there, staring me in the face was a HUGEMONGUS bigger brother to the other crab, atleast 4 times his size, same crab, just huge! Staring at me with his red eyes. He moved to quick for me to get him with the net, but thought id post about it.
Here is the picture that most closely resembles them, can anyone give me any more details on this possible sixline killer?

They both were very hairy looking like this one with red eyes.

Here's a thread with more pics, including the one I had that looks like yours. I've always heard the red eyes thing, but my crab never gave me any problems and he was very shy.
I do remember that after a molt, he would barricade himself into a hole and put CC in the entrance. As I said, mine only ate corraline algae, and whatever I gave him. I watched him every night, never had any problems...
But that's mine.
