Mystery Crab

[obx fish]

I noticed this crab that just appeared after having out tank for 6 months now. I don't have a picture and no way to get one...hopefully a good description will help...
He or she has long front arms with like fans on the end that it seems to use to catch food with...then it has long pinchers that look like they come from mid body and they are bluish gray with white specs...then it looks like it has black and white striped back legs. It would fit on a dime easily, I haven't been able to see what it actual body looks like. Does anyone have a clue? Thank you for any input or ideas!

No we don't have an anemone. We did a long time ago...but it was shipped in poor conditions from another company and it didn't make it.
