Not sure what this is - maybe bad, maybe good?

I have these little things growing in multiple locations now out of my liverock. They seem to be embedded in it.

I wanna say pineapple sponge (neutral) but it is very difficult to positively I'd with the pictures provided.

I'll try to get some better ones tonight with the lights off. It's definitely green and shaped like a leaf.

I've had pineapple sponges before but I remember them being white and roundish.

You may have to grow that out too see.

Plucked one off a rock. I can see it growing in some other places on the very top of the rock, towards the light.

Haven't seen it anywhere low light yet.

Looks like macro algae. Google Halimeda.

I have carpeting halimeda in my tank, in the refugium. I didn't think it had gone sexual, it was white with the lights off but green and white with them on.
