New tank, what's this red bumpy stuff?

My tank is only a week old and it's still cycling but I noticed a lot of this dark red stuff sprouting on the bottom side of my my rocks. FYI I don't have lighting yet if that matters. Thanks.

It looks like maroon coralline algae to me, but it's hard to tell from the picture. Is it forming a crust like coralline algae or is it easy to remove. Coralline will encrust on the rock.

 

Perhaps Formaminiferans.

This link will be of some assist in ID some of the most common creatures you will see.

I did a google image search for corralline and actually found what's in my tank. Funny thing is one of the first links for this was off of 3reef...

I guess it is a fruiting form of coralline algae.

 

Yes, there's different growth forms. Geniculate, non-geniculate, stromatolithic, etc
