ID unknown hitchhiker (coral? pest?)

I am not sure what it is, but it is very pretty in my books. If it is not a pest, I wouldn't mind a few more of them!
Though I would be curious to find out exactly what it is.

Very pretty, was what I thought too!

But sometimes the worse they are, he he!

Curious to know as well.

Does it react to light or you touching it (use feeding prongs or something in case it is toxic)?

If it does react I'm leaning more towards an anemone. If it doesn't react, and is unchangable for the most part from one day to the next then I vote for sponge/tunicate too.

I used a glasseye dropper (used for feeding frozen food) and gave it a thorough poking - absolutely no reaction, other than being slightly crushed. It was hidden behind some mushrooms and I thought it might have been a majano, but it wasn't until the mushrooms retracted some that I got a clearer look.
But what got me confused is that it doesn't look like the sponges I am used to seeing (not that I have seen many varieties yet). It almost looks 'feathery'.

I was just thinking it looked kinda too feathery to be a sponge, but I have no idea what it actually is. Sort of looks like a feather duster but obviously not without a tube to retract into.

Sorry, I now see you answered my question in your first post, I just didn't read it all...

Not an anemone then...but I'm not totally sold on it being a sponge or tunicate either. Try sending your pics to Wet Web Media. http://www.wetwebmedia.com/ click on "Ask WWM". They are quick at replying.

Out of curiosity I emailed them, they believe it to be either:
Eudistoma sp. Heron Island, Capricorn Group, Queensland, Australia.

or possibly
Distaplia occidentalis
http://emeralddiving.com/id_ascidians.html

It could be either, but I can't seem to get a good enough look at the one in the tank as it is at a funny angle and it hidden behind mushrooms.
