what is the coolest thing you have gotten on your live rock?

the coolest thing ive ever got would have to be some large feather duster worms, some type of zoanthid coral and another unidentified coral specis but they have doubled in size since i got them sorry cant post any pics my digital camera is broken at the moment

I got some black sea urchins - haven't seen any pics that look just like them but they've grown steady and seem reef safe - they can be bulldozers if stuff's not secured well. I hadn't purchased any rock for about 3 months when I saw the 1st one - about the size of a round dime. A couple months later I saw the 2nd one - no others - just the two. They're now about the size of baseballs.

Nessie!

A couple weeks later, I actually saw what it was:





He's a stomatella snail. Hands down the coolest hitchhiker I have.
