Are these hydroids?

[CubiX]

I've been trying to id these polyp looking animals on my rock.

They are purple/pinkish in color, they retract their tentacles when touched, the appear to have runners connecting them, though I'm not 100% sure. Almost all of them have 8 tentacles, some 7.

They seem similar to the hydroids on this page:

Are they hydroids?

I'm not sure what those are but i have a frag that has some of the same things growing on it. I'm 99.9% sure that those are not hydroids but cant tell you exactly what they are, sorry.

hard to tell by the pics
but from what i can tell they do look like the hydriod

i cant think of any polyp that would look like that...the tentacle things look feathery but it isnt a feather duster i dont think
unless they look like that cuz the pic is fuzzy

 

[CubiX]

No, they're not feather dusters. But the tentacles are sort of feathery.

Maybe i'm not seeing something in your pic but if you are talking about the purplish polyp looking things, those are NOT hydroids.

Go to google images and type in hydroids. The very 1st pic has a rock with what you have and hydroids. The hydroids are in the middle of the pic, not the polyp that you have and are in the top of the pic.

I agree with sufunk...those do not look like hydroids. Not sure what they are though...

clove polyp (coral?)

That was my first guess yes... The fact that they have 8 tentacles supports that. But all clove polyps I've seen grow much closer together.

Maybe they're "special" clove polyps?

I found this pic on webwebmedia

Mine look exactly like the tiny polyps in the center of the pic.

The wetwebmedia expert says:

This is very likely an encrusting/creeping Gorgonian (Sea Fan), like Briareum... can be very invasive, competitive. I would do as you state (if you desire to culture the Clove Polyps) and separate these colonies, keep them to their own "patch rocks". Bob Fenner
