Help identify what's on my zoa

[SharkAttack06]

I'm new to zoa's. I picked up 3 about 3 weeks ago, they seem to be doing great. I was moving them around today to start permanently mounting them and noticed the "dragon eye" has these long plant vein like things coming off of it. Not sure what it is. Any help?

Looks like hair algae but doesnt look very good. #reefsquad?

Not sure on what type of algae, maybe mermaids wine glass? I'd try manual removal.
