Help!! What is growing on my Zoa?

[zachSalty]

These guys have been always open and so full. I discovered this line with black dots and maybe eggs on them? I have attached pictures. All my other spas are big a beautiful. These guys are sorta just opening and closing

They look like nudibranchs…I’m assuming a zoa eating type. Dipping removes adults but not eggs.

How do you get rid of them

The eggs have to be manually removed; I’m not aware of anything that kills the eggs.

I took the coral out and found 4 live ones and then plucked the eggs. It is wide open and happy again. I’ll have to keep a watch out
