ID on some inverts (sorry, no pics)

[fishstixs05]

I recieved a tank with lots of things in it, some of which i am not unsure about some things
1. He had several ricordea in the tanks, and on a lot of the rock are small polyps that are like miniature rics: they have the oiter ring of tentacles and the larger ones are showing the bulb-type things on full grown rics. Are they babies, or could they be something else? many fell off of the rocks, and they are growing in a tank within my tank
2. We found a couple big worms (one was 12 inches) that look exactly like earthworms. I remember people talking about these, but dont remember the name
3. last ones looked like a sponge, and were round half-balls stuck to the rock. They are sort of hairy, anyone know the spenge species?
Thanks,
Ben

I read Rick's response earlier, and I didn't think it was a bristle worm either. I did some search and found the following thread:

I too have these same worms in my tank. I was told the same thing, that they are Eunice worms. But nobody ever said if they are good or bad. does anybody know? I recently took one out of my tank that was about 10".
