Anyone know what kind of macro algea these are?

This is growing on my seed rocks for my new tank any ideas what these are called?

red stuff looks like Gracilaria...The other stuff not so sure, if I had to guess I would say Kelp maybe?

Yea the more I look at the green stuff the more it looks like a small version on kelp I have seen in commercial aquariums. I would have thought my tang would be all over this stuff but he doesn't go near it.

red stuff is gracillaria. green stuff looks like caulerpa prolifera.
just guessing though

+1 red gracilaria (really suprised your tangs have not devoured it, this is their staple diet in the wild)

The green does look like a kelp of some sort. Does it have runners along the bottom of it? If so then it is a caulerpa of sorts, not prolifera though. I would be interested in some though if you would like to sell/give

Well I have a pretty empty tank that really could use some frags. Interested in trading for some?

Gracilaria for the red, the brownish green stuff looks like Dictyota of some variety.

I am pretty sure the green is a type of kelp, I have had it before, but any grazing fish seem to love it, so you have to choose livestock carefully if you want to keep it, same for the gracilaria as well.

I don't really have anything ready to frag right now to be honest. I do have tons of macro algae's I can trade with you though. What I have available can be found here:
