Another crab on live rock for ID

[jeffvmd]

I found this little guy in my cycling tank.
I just wanted to be sure if this is an emerald crab.
The critter has kind of an olive green carapace and hairy legs which are sort of similar to the rocks in color.
Here is a not so good pic I was able to snap of the little guy.

I can't even tell what's what in that pic lol Bottom line crabs are no good in general especially ones that are hairy. I would flush it. There are only a few kinds of crabs that are really reef safe arrow crabs are one of them not sure of others but I know there is very few.

If it's green with hairy legs,, it's a emerald crab which is reef safe and good for your tank

Kinda hard to get a glimpse of the critter for a better pic. I'll try to get a better one if I have a chance.
It's the critter in the center of the pic where all four rock corners meet.

@bigdog1428 - Yes only the legs are hairy.

Will it be fine while the tank still cycles or do I need to get him off 'til its done? It managed to hitchhike the live rocks I got to cycle this tank.

I wouldn't chance it man..crabs are opportunistic feeders and bad in general. If you have snails, I'm sure you paid for them and it's not worth it to risk putting in a crab you got for free by accident that will probably cost you money in the near future. I have heard of emerald crabs being reef safe they generally are classified that way but I have also heard from several people they ate their snails. I personally would not put any kind of crab in other than an arrow crab which also eat bristle worms,not to mention they are cool as hell.

looks like an emerald to me. just make sure the tips of his claws are flat and not sharp. emeralds are generally harmless as long as they have something to eat.
