ID This Red Macro Algae

[FinzAquatics]

Hey Everyone,

I have had this red macro growing in my tank for quite some time now.. Not 100% on what type it really is.

My initial guess is a type of graciliaria, but not sure which variety.

Look forward to find the answer!

That's what I've always kind of thought, but then I saw some people selling graciliaria mammillaris which looked different.. There's looked more like something similar to g. Hayi. Either way I second guessed mine.

But after a second it does appear to be graciliaria mammillaris

The one in the bottom right area? Definitely Mammillaris. It grows different depending on lighting. Intense lighting over a long time = thick layers stacked. Low lighting will create thin, taller growth.

Mine tends to be in more shaded areas so I'm getting more of the long thin growth pattern
