I have made 2 blue circles around these green fleshy things. Hopefully you can see the circles.
I have not seen them move there location, but they do change there shape. they also open a little mouth like hole that looks like the mouth hole of a clam.
Anyone know what they may be?

Mods if you think this will get more views/ better chance of being answered in a different forum could you move it please.
Thanks

I'm going to hazard a guess with....sponge? are there multiple small holes?

I would say sponge, nice white zoas!

+1 on the sponge. I have black and green encrusting sponges in my tank.

I was thinking sponge and you all are probably right. It just seems really soft and fleshy and the surface is smooth. Then every once in a while, the peice up higher will puff up a bit then open a small hole.
weird. I didnt figure its anything to worry about and if it is a sponge good for me.
Thanks Alix its a really good looking rock and the white zoa set it off. i stared at this peice for about 2 weeks before buying it.
