I'd red bubbles on zoa

[adamfrer12]

So I have noticed that I have these red bubble looking things on my zoa Rock. They are slowly getting larger. Any idea what it is ? Good or bad? If bad how do I get rid of it.

red bubble algae...
rare and very beautiful, might disappear just as easily as it appeared. I'd simply enjoy it's beauty and benefits, herbivorous fish or Emerald Crab could easily keep it in check or decimate it.
