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

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.
