Anenome?

[RLimb1]

Hi Everyone-

New to the boards. Just set up my first tank, and managed to get some good live rock that was from another tank tear down. I have some soft corals on the rock as well, but am growing what look like a small anenome. I tried to take several pictures. The first shows the orange color at the bottom beneath the Kenya trees, and then the 2nd pic is zoomed way in for detail. Any idea what these are?

They look like little fan worms to me, that's just a guess...However I'm sure that it's not the glass anemone you fear called aptasia.

Those are the Hydroid stage of jellyfish - not a good thing. They have a powerful sting and can outcompete corals for space.
