There are about 10 of these little things that have popped up on this rock over the last few weeks and I was just wondering what it is and if I should remove them?
my vote is majano, and I would kill them before they become 100. I just spent 2 hours with a twizer to take out 30 of them. Once they dig into your zoa colonies, they will expand and multiply and expand more. They smothered out lots of zoas before I finally bite the bullet and went down on them.
