Red algae

I have growing on a small rock what I believe to be; Fauchea sp., a red plating type algae. It isn't hurting anything and I don't have it in direct contact with any of my large pieces of live rock. Any ideas, is it a pest? Is it just a benign part of my reef tank? The weird thing is, I have no idea where it came from. I have had my tank up for almost 9 months and last month it just appeared out of nowhere and started growing a small piece of rock in the tank. As always, thanks for your help.

Hello, Illinois!!!!!!!

 

Hey Steve,

Thanks for the great links. It is 2nd picture, in the 4th row of the google link. the malegameto.jpg, I didn't copy the link, because it is about 3 lines long, but that is definitely it. Harmless? I like how it looks (right now that is).

Fauchea link

 

Thanks, great link, that is what it looks like. So, is it harmless? Do I want it?

 

Finally, some pics. So, what is it? Is it harmless? Do I want it? It is growing, so if I do, great!!! Thanks for the help.

 

Those pics look like some of the red macro algae that grows in my tank.

Edit: It could be a Halymenia sp.

 

I think you are right, thanks.
