Help ID this worm and his friends

[ScubaSteve]

I can't quite make out pic #4 but they almost look like a colony of tunicates. If it is a bunch of indiviual "chambers" with two vents in each then it is likely a tunicate. Does it look kinda like this?

If got small, purple individual tunicates in my tank. Harmless and cool.

Oh, forgot to mention, could also be a sponge...

They are sea squirts I have some in my tank as well they come in a bunch of colors.

Thanks everyone!

you need to email your picture of the peanut worm to Melev because yours is WAY better than his!

I've never seen a peanut worm go from hole to hole?
Peanut worms were all I had for a few months on some fresh caribbean LR and they never did more than opened their mouths (like a small flower)...

They weren't clear either, you could not see into them at all, they were more opaque like palys...


That looks like something very different than a peanut worm to me

Do you have any pics of them with their mouths open?

All I ever manage to catch of these worms is the hole to hole view.
I've seen similar looking ones going from a rock into the sand a few inches away and digging around in the sand for along time, but never seen them extend or retract.
They typcially are retracted in the morning, and come out later in the day.
