Name this critter. (very odd)

I'm going to go with "sea spider" of some sort. If you have any idea what this is, or what it might need from me to survive...please tell.

You know I was cleaning this coral for probably 30 minutes before I saw it. It is so well disguised!

A close up...

Yes...a hitch-hiker on my part 1 of TBS rock. I should have mentioned that.

looks like a sea spider to me. I also received a purple one on my TBS rock. It lived for about 3-4 weeks and I haven't seen it since. Was cool to watch while it was around.
