saltwater scorpion?

[chris77]

Is there such thing as a saltwater scorpion? There is something I've never seen before hiding in my rocks. For sure not a crab as I have a couple of those. This has a long straight body and is black and yellow.. Any ideas?

I would guess a mantis shrimp...  Do you hear any clicking noises coming form your tank?  Does it look like this??

Arrow crab?

I dont think it looks like whats in the link pic you provided.. Not that much yellow but that guy looks creepy. Are arrow crabs something to be worried about? Or should be removed? Are they black with a bit yellow

Arrow crabs and mantis shrimp both come with different colour variations.  Try doing a google image search and you should see a bunch of different colourings.  Arrow crabs look like huge creepy spiders to me.

Arrows have been known to eat slow shrimp but are supposedly reef safe...  Although I think I heard somewhere about them eating zoas.

Could never figure out why my zoas wouldnt thrive but other LPS would.. during a WC i accidently knocked rock onto my arrow crab and killed him, few weeks later and my zoas are thriving and multiplying already...
