Can you help me identify this little guy

[Plato30]

This little specimen popped up on some live rock of mine after I finished cycling the tank. Any help would be greatly appreciated.

It may be bryopsis. Doesn't look like anything good though.

I'll second that!

Thirded. If possible remove the rock and take a look at bryposis removal techniques. Stuff sucks.

Think of it as a green plague, about to happen. Remove all you can, and get something that eats it.
