Are these hydroids?

No idea what the brown stuff growing on this rock is (next to the mushrooms)...hydroids?

It looks like a coral. Maybe a goniopora or alveopora?? Is it firm and stony ?
I think you scored.

I see what appear to be brittle star legs. The striped things.

Does not look like hydroids. Hydroids usually form a thin web that interconnects the polyps, not a solid mat.

This is one form of hydroids:

Yours looks like an encrusting mat, possibly a gorgonian, though the polys seem small and short. very likely something else, but does not appear to be hydroids.

Thanks for the replies. I just wanted to make sure it wasn't some sort of nuisance that I should remove before it spreads.

I didn't read your response close enough the first time. I have two other goniopora in the tank but this looks different. The polyp looking things appear retracted in this photo but they do extend out a little more from time to time...looks a bit fuzzier some times.

LOL...yes I also saw the brittle star legs...we have quite a few of them in the tank. These kind are mini's, right?

Theres a lot of different sub species of both.
Total score. Congrats.

Yea probably the mini stars.

Thanks! If it is a sub species it should be okay next to the mushrooms, right? We're not particularly wild about these specific mushroom anyway but I've noticed the shroom's are growing faster than this other "thing".

It looks like porites to me. I wasn't looking at the rock when I first checked.

And yes, I think those are mini brittles.

Interesting...it does look an awful lot like porites. I'll read up on those too! Thanks so much

It's nice to get a good hitchhiker for a change...rather than the pests.

No, I posted the same thing twice. You can't delete a post, so I changed it to "Double post"

Ah, okay. Whewwww...I thought "holy cow...I'm in trouble already."

I would say porites as well. They used to come in all the time on fresh live rock.

The little white antennas are spoionid worm. I have seen them in my tank from time to time. As for the brown stuff growing it almost looks like an encrusting monti or possibly sps that is encrusting right now and will shoot up tips at some point. Also the other legs are micro brittle star I have millions of them.
