Found this on one of my live rock...anybody have any idea what it is? It may be upside down as we moved some rocks around today and removed our UGF. The color is pretty accurate, a kind of purple with a white "head".

Does it move? My guess would be sponge.

I think it looks like a sponge also. Is it hard to the touch? Anything that comes out of it that we cant see in the pictures?

Could be a zoa polyp too

It also looks like a tube that a worm creates (can't think of name)
I've seen these in my tank connecting from one rock to the next...

It does not move and nothing comes out of it. Not sure if it's hard or soft as I have not touched it. But I can do that later and report back. It never opens and really doesn't change much. It's been there several weeks but it was not in a easy location to look at before.

Doesn't look like a vermatid snail. Could be a zoa/paly polyp, but can't tell yet.

I am fairly certain it's sponge. The white part is damaged (potentially when you move the rock around).

I would love if it was a sponge! Time will tell I guess. How quickly do they grow?

just wanted to clarify that I wasn't referring to vermetid snails ;)
but anywhoooo....
its always so fun finding new life!! :bounce3:
growth all depends on water params, lighting, etc..
I have sponges that grow fairly quickly and ones that haven't grown in 5yrs!!
