Macro algae ID

[Satori]

I have 6 different kinds of macro algae in my fuge, and really only know what 3 are. I know I have green hair, chaeto, and halimeda.

I think these first two are caulerpa?

How about this "spikey" one?

And, is this red macro a type of kelp?

I have that spikey one too in my main tank, it has little more of a silvery sheen but the shape is the same. It has stayed nice and low and formed a nice clump.

I got an ID on that one in another thread as razor/sawblade (Caulerpa serrulata). I found a picture, and it's the same.

And the red stuff appears to be Halymenia floresia

Mike, nice looking macros. Been awhile since I looked them up, but I believe the first pic Caulerpa in front of the cheato is Caulerpa racemosa. The serrulata, was correct and it is commonly called razor caulerpa. It is one of my favorites. However, it tends to grow a bit slower and is often outcompeted by the other fast growers. Hopefully it will take root and hold.

I believe the red macro is spelled Kalymenia sp. I had lots of this at our auctions. I also had the red razor too, not sure if you ended up with any of that.
Cheers

Scott, I think I did get the red macro from you. I found pictures on Google using Halymenia.

All the macro in the fuge is growing very well. Here's two pics with almost exactly 1 month gone by:
