Help: Featherduster or Apastia?

[Brent F]

I know the picture's bad but can you help me ID this? They are about 1/2 inch diameter and disappear into the rock instantly if anything goes near them. I'm guessing featherduster but want to make sure they aren't Aiptasia.

Looks like a small duster to me but im still new...lol

Looks like featherdusters to me. Aiptasia only seem to disappear like that when you poke them

[hillbillyreefer]

I've got lots of dusters that look just like that. I've also had aiptasia and it doesn't look like that.

Thanks, I'll leave them alone then. They are on underside of a ledge in my tank.

Duster I would agree.

[justinl]

yeah looks too frilly to be an anemone (look close for distinct tentacles). I vote duster too.

I say it looks like one of those ever elusive hedgehogeda saltwaterous!

[SeaHorse_Fanatic]

Featherduster.

I have these things all over my tank in different colours and could never get a pic to ask what you just did. That's a bonus!
