Friend or Foe? What is this thing?

I just noticed this thing below one of my zoas. I added some corals about a month ago so not sure if I introduced this then.

Those are Corallimorphs (A.K.A. Ball Anemones) - they're related to soft mushroom corals; sometimes they reproduce quickly, but they're generally harmless and pretty neat.

Like @ISpeakForTheSeas said, yeah just a ball anemone. Some consider them pests, but they're generally harmless so I always keep them, and they make for nice accent organisms for the rocks.
