Mysterious Growth

[vieiras]

Hello,

We have a growth forming around our rock anemone and we are not sure what it is. We used to have calurpa algae in our sump over a year ago but that has since died. Is it possible it may have resurfaced? If so, how would I get rid out it?

I can't tell for sure from the pics, but it looks like either Caulerpa or Acetabularia algae to me. Some herbivores may eat them, or you can manually remove them (you just need to make sure you remove the "roots" to keep it from growing back).
