Are these Zoas?

[Ajae]

I've had this mushroom in my tank for 2-3months now. Just this week I noticed these on the backside on the rock that it came on. I had seen them before but they didn't have any color to them and thought it might have been a new mushroom growing. So are these Zoas or another mushroom coming in?

look like zoas to me

should I separate them? Will they sting each other to death?

They'll probably be fine together but I'd separate just to get better growth! Good luck!

Cheers, thanks!
