ID of a Crab

Sorry, there's absolutely no way I can get a picture of this one.

Several days ago I was looking around on the live rock and noticed something that looked alot like legs. At first I thought it was a really sparce feather duster. I checked in the same hole for several days and noticed it each day in a different place. Well one night I decided to check that hole to see what it may be, on the off chance that it comes out at night, and it appears to be a crab of some sort.

It's very spindly, almost resembles a spider. I'd say it's no larger than about a quarter of an inch total. It moves extremely slow, one leg at a time. I can't really describe the body because I can't see it that well. Oh yeah and it's clear for the most part.

If anyone has any idea I would be greatly appreciative. I was thinking something along the line of an arrow crab or decorator crab but I was hoping someone has had a similar account.

man that is hard to make a guess without a pic. I would say gorilla crab but if its spindly I would not say that.

arrow crabs also look like spiders, it may be a very small verision of that
