yellow polyps

NOPE I know what those look like.

Seems like little feather dusters? Hydroids a possibility but I don't think so.

Either way neat.

Get a picture of them retracted I would say, but they looklike cluster dusters to me.

I have never seen them retract at all. That is how they look all the time. I have been looking around on the net to see if anyone can help me on this but I'm having no luck.
