Tiny brown zoas?

[Angel Flores]

What is this carpet of polyps? Small brown tentacles with blue/purple centers?

 

[DDenny]

Looks like clove polyps pretty invasive from what I remember.

 

[Solo McReefer]

Sympodium?

I had some that was blue. It was a nuisance

 

[DDenny]

Maybe Sarcothelia from my research

 

[ISpeakForTheSeas]

Yeah, an invasive octocoral (Clove Polyps, Sympodium, Sarcothelia, Anthelia, etc. all look similar and I haven't learned how to tell them apart yet) - some are only mildly to moderately invasive while people have torn down tanks for the others (Blue Clove Polyps are known for this).

It looks like blue or purple clove polyps, one of the most evil invaders of all. I had to do a rip clean to get rid of them.
