Good Crab? Bad Crab?

[Spaz059]

I think this is the culprit behind the death and destruction of my cleaner shrimp. What is it?

 

[BL1]

I'm not sure what kind it is but, it's definitely a bad crab. Dark, sharp claws = predator

 

[Hiker4twenty]

Kill it!

 

[reeffreak]

It a type of xanthid crab....not considered reef safe.

Had one that looked exacly like that. I determined it had killed my lawnmower blenny. This little @#$$ met the business end of a bamboo skewer :mrgreen:

 

[Spaz059]

So I should kill it? Or is there someone who would benefit by having this other than me?

 

[BL1]

Nope, definitely kill it, that crab won't benefit anyone to have it in their tank.

 

[Bifferwine]

It could go in a predator tank. It would be a snack for a trigger or puffer.

 

[Spaz059]

Ok, so I will just take it to my guys at the LFS they will have something to do with it.

I had one of those in my tank and while I was on vacation it feasted on like $250 of coral. He met my knife :D. Enough said

UGH...We knew we had some type of 'hitchhiker' crab in one of the newer rocks....but only caught a glimpse of it once or twice......
Then we had the "mysterious" missing fishies....then the whole tank disaster.....

Well, finally found the same litte booger last night.....twice as big as before and looking rather menacing.....Identical to the one in above photo...

He's gone--nuff said!

Well next time I see him we'll have a little talk. He has eaten a colony of polyps and 2 leathers since I first asked for help

damn getting unwanted crabs sucks :( sorry to hear about your tank and the unwanted pest.

Looks like the one we have. I think the store called him a black claw reef crab (I believe). Can eat some soft corals they said and possibly small fish and snails. He's still in the tank somewhere and so far all fish accounted for. But they said it's not likely he would be able to catch our damsels.

We "lost" 2 damsels and one peppermint shrimp---oddly about the same time I bought the new rock and noticed him scampering around looking for a hiding place.
I would not think something that small could cause such havoc..:death:.....but, like I said, he was now twice the size he was 2 months ago......

 

[jen_1122]

I should say I think he's in the tank still. Haven't been able to see him for some time. But, I know he was in the tank about a month ago. Not a sign of him since.

Trust me--he's there.........Didn't see mine for over 2 months.......even thru the tank "disaster" he managed to survive and thrive...UGH!

Thanks, guess I'll have to keep my eyes open.
