Need help with ID! These things are growing over a zoa colony and it seems it's killing them because they are closing up. I thought this was Aptasia but it looks like none that Ive seen. They can detach themselves and reattach. See pic below.
What in the world is this??

Its an algae of some kind id say... what do you think @saltyfilmfolks
I'm looking at a radial symmetry and what appears to be a central mouth, so thinking some kind of coelenterate. What kind, though, with those jagged tentacles . . .
@Lionfish Lair, any thoughts?

COOOL>oh maybe not....sorry about the zoasAnd another pic.
That looks like the bottom of it. Is there a mouth on the other side?
I want to say its a nem. or shroom.
it should smell like an alge if it is.
Can we see them on the rock?
@Tahoe61 heres one for you.
@Lionfish Lair you might want to look too.
That's the top of it. Im pretty sure it's not algae, at least none that I've seen. It's got a rubbery soft coral texture and the tips of it has these green mini "branches", almost like a Kenya tree but these little guys are tiny. I tried getting some pics on the rock in my tank but due to the lighting, it came out really bad using my phone. I'll whip out the dslr tomorrow and try to get better pics. Thanks for all your help
There are a number of anemone species that have tentacles that mimic soft coral (Phyllodiscus, Phymanthus, Actinodendron, Talassianthus, etc.). May be a very young one of these, perhaps?
It's possible as they can be brown, green, white or even pinkish.
I forgot one genus: Magalactis. It's too bad that more of these unusual anemones aren't imported more regularly.

I did some googling and it does look like a very tiny hells fire anemone. Well I got rid of all the ones on that zoa colony for fear of it being a bad critter since my zoas have been closed ever since they appeared (about 10 were on that rock of zoas) I saw another in my tank yesterday and left it alone but today it seems to have moved and I can't find it so I can't get that pic on the rocks :/
Its just cool factor.
OH hey whats that?
Oh, my Hell fire anemone.]
Time to set up the Pico!
Since the OP is finding a bunch of these all together, could indeed be one of the many 'Majano' species.

I'd try an iodine dip. Zoas and palys can be soaked for a longer period of time, bug if it's killing, or even stressing out your corals it needs to go! Use regular OTC iodine, use your tank water in whatever volume to covers the zoos, then add the iodine until the water is BLACK. Add zoas and walk away, for up to 12 hrs. Then put the coral straight into the tank. When my Zoa started falling off this was recommended to me and the crap that was left in the much lighter iodine water was surprising. You have a nasty little hitch hiker that needs killin'!![emoji1] what name it has doesn't really matter. Just get its nasty seltzer away from a much more expensive coral

looks like parsley, were you eating dinner over your tank? 
That's a strange one.

Marionia sp. Dendronotid nudibranchs
Matches exact pictures I have in a few books
They sometimes have elaborate cerata and often resemble their prey animals which include soft corals and other cnidarians
