Im guessing these are zoos? They dont seem to be growing?

So I got this clump of zoos? about 2 weeks ago but they have not gotten any larger and I dont see any new growth. I also have a blue one that only has 4 polyps on it and it too has not sprouted new growth.
My xenia and other 'flowing' coral have doubled in size.
Do you think my lighting is not strong enough or does it take them a couple weeks to get going?

Zoanthids are relatively slow growers. When they are closed you will be able to see babies spreading if their are any. You should see noticeable growth in 2-3 months.
Zoos usually don't need much light, but they need some decent light. With that being said, how much and what type of lights are you running?
That's a very nice colony by the way. If they are opened up like that in your system they are more than likely happy.

xenia grow extreamly quick! IME they are the fastest that I own.
I have had some radioactive dragon eye zoos that have been growing extreamly fast started with 15 polyps now I have over 80! But i have the same tipe as you (eagle eyes) and they seem to be a little slower.
