Can anyone please identify what's growing on my zoa rock? Looks like some sort of green leaf....

try making your lights a bit whiter and take another picture. Tough to see anything with such a high blue level. I think I see some sort of macro algae, but also not sure if thats what you're referring to because it looks like a blue leaf to me.
