Amazing emerald crab!
 

Just picked up an emerald crab at J&L today (Boxing Day baby!!!) and so far I'm impressed with it. I let it out of the bag, and not 3 seconds after initial touchdown on the sand, it started eating cyano! Within 30 seconds it had cleared a quarter sized hole in the cyano. Then it slowly ate a trail into my LR and dissapeared into the rock where I'm sure I won't be seeing it very much from now on.

This crab rocks :D

I bought mine a month ago and once he hit the rocks I thought the same thing,but he is every where and only hides when startled...
He is really cool to watch

I've been thinking of one but... crabs kinda scare me, I don't want them to kill my snails etc... my blue legged hermits have ripped a few snails out of their shells and I have provided TONS of extra shells for the BLH's... thinking of introducing them to Mr. Trigger..... not really.. just tempted to threaten them.... Oh yeah.. there is at least one BLH that eats the polyps on my Montipora
