ID Black Crab

[aaron229]

Hey does anyone know what type of crab is this ?????
It came on one of my rocks i guess and it's growing very fast I think. It was about 1/2 inch when i first saw it and I guess it has been like 3 months. Now it's like 1 1/2 inch big. The feet look a lot like the green emerald, but the body and claws are completely black. Please help ID

I don't know what it is but they are common on live rock. It is omnivorous and will eat anything it can catch including many corals and other inverts.

So do you think that I should try to get it out of my tank ?

He's tough to see in your pic, but definitely keep an eye on him...

If you catch it, you should prob. get rid of it. It may harm other animals in your tank.
