Please ID

I bought two mushroom covered rocks and after two weeks (and after coral rxing) I see two things growing ... One looks like a white poofy thing and the other some kind of green plant growing? Can anyone help me with ID? Should I be concerned?

Thanks in advance !

 

The white thing looks like a pineapple sponge. The macro algae is Halimeda.

 

white poofy looks like a pineapple sponge, no worries, you'll prob get a bloom of them, but they usually go away

greeny looks like a macro algae, I'd get rid of it while its easy, although I can't really tell for sure.

EDIT; what Vinny said

 

Thanks y'all !

 

The Halimeda is a slow growing calcareous algae. Not invasive and kinda cool looking. Its also called money plant.

 

Halimedia is easy to remove when you want to. I like it too.

 

Yeah I thought it looked cool but things that grow that fast (in my experience ) aren't usually good! I feel better now thanks for the info.
