found unknown crab in my 120 reef!

[True359]

I was looking at my tank today and was surprised when I found a "hitchhiker" crab. It's about 1" big. It's body is a solid porcelain colored and it's legs are neon purple. Anyone have any ideas on exactly what kind of crab it is and if I should get it out of my tank before it becomes destructive. I can get a picture if it would be helpful.

Thanks,
Eric

And for the record, "porcelain" is not a color.

Just saying.

Also for the record, if you read the twelve million or so "what is this crab and what should I do" posts on this forum, and poll the answers therein, you'll see these results:

99.999% - destructive crab, remove it, add butter
.001% - don't add butter
