Could anyone ID these for me?

They have sprouted from the live rock and i'm unsure what they are!

Could this be aiptasia?

brown blob- it contracts in and out and is v wierd!

this is a worm like creature that can be found poking out of one of the holes in the live rock, it's very small.

We've also got a bristle worm but i haven't got a pic of him!

Fantastic! - havent got a clue what any of them are - but this is what I'm looking forward to!

 

[SHELL]

It's great, everytime we look there is something new, we have tonnes of feather duster that have popped up, fantastic!

First one I'm almost sure is Aiptasia...

Second one, perhaps a tunicate

And third is a bristleworm

thanks Chhltcow

I have just had a look at tunicate and they are very similar, are they a good thing to have? as i have never seen anything like them before?

Cheers

Tunicates are harmless filter feeders. Usually they grow in dimly lit places with high water flow, such as a canister filter... so you never see them. When I was moving rock from one aquarium to another, I found tons of tunicates and sponges on the underside of rocks or in little "caves" in the rocks.
