What are These?

I have, well more than a few of these guys and would like to do some research on what they are.

Looks to me like some type of button polyp. Is it in a low light area? I had a colony once and the ones that were shaded would stretch out like that and get tall.

They have some decent light, about 12-14" from the bulb. The bulb is a t5. Probably an older bulb though. I got it used so not too sure.
You think maybe a Brown Button Poly?

If its brown then i'd call it a brown button polyp. Button Polyps, like Zoanthids, are sold under trade names based on color. The actual species is incredibly difficult to tell, even to marine scientists whom specialize in studying polyps. The good news for you though is the care requirement for whatever species of polyp you got is gonna be pretty similar to the vast majority of polyps in that genus.

I will say they need more light, if you see polyps stretching like that its because they are trying to get closer to the light. They could be brown now but if you get them under the proper lighting they could end up being neon green, you never really know with polyps until you get them somewhere they are happy.

Thanks for the help.
I have some mushrooms in that tank that are also reaching up. I'll head out to the lfs for a new bulb.
