There are 2 brown tube like structures just to left of the blue sponge on the bottom of the rock in the pic on my christmas tree rock. They look like sponges but have a definite opening that retracts if touched and nothing comes out of the tube...any ideas?? The hole in the end is about the size of a pea. Thanks.

Probably Vermetids Snails. Here is a recent thread on them: Dear god! Help with Vermetids (tube snails)

No definitely not vermetid snails.

I have plenty of those. They are soft and nothing protrudes out of the hole. They look like a sponge.

feather-duster worm I believe. I have them in my tank too. They are harmless.

The third pic is similar

Not a feather duster either.

Nothing comes out of tube as stated above.

More than likely a Barnacle. I've had a few in my tank.

Isn't the outside tube of a barnacle hard? Cannot find a good link for info. online? These move and retract and feel like a sponge when touched?

I have looked at various times of day and night and have not seen any feeding legs. Wish I could find a live picture that looks like what I have?

It's a tunicate. They're harmless filter feeders.

Thank you. After some research they do appear to be a species of tunicate. Thanks again.

sponge or trunicate, hard to tell.

sasscuba · 01/13/2008, 09:30 PM

It retracts when touched so it is not a sponge I have ever seen.
