what is this growing?

[kratie]

First time I saw this was today

coming out of my zoos is a small tentacle (pretty sure this is normal) but in the picture to the right there is a small rock and something started growing today and lifted the rock up look under the small lighter colored rock.

any IDEAS!

thanks

just curious.

I don't think it's a tenticle. It simply looks like the zoa expelling excess zooxantelae which is the symbiotic algae that live within their tissues.

I would say zooxanthallae also.

Kratie,

 

Correct me if I am wrong but I thing you were trying to ID the thing I highlighted. As for my help, I won't be worth much since I don't really know but hope the image helps others help you out.

Thanks for the highlight of the area I should of done that in the first place thats the part Im trying to id, just curious it was strong enough to lift the rock. I know its a small rock but still weird.

It could be a sponge of some kind. A close up pic would help a lot.

Sponge or maybe even a hitchhiker bi-valve like a clam or muscle... :| Close-up would help as joshnemily said.
