Bryopsis?

[baseballfanatic2]

Is this bryopsis? This rock was dry for a good amount of time, just used it to set up a new tank and now it has this growing along with the diatom bloom that new tanks create.

It's not. Bryopsis is much finer. Almost feather like.

 

[Darth George]

Some kind of macro.

 

[Darth George]

Almost looks like a genus of caulerpa.
