ID Red Macro

[Hef]

Can anyone identify this. It seems to be growing pretty fast in my refugium. I put another piece of it in my tank and my yellow tang ate it very quickly. I'm leaving this one in the fuge for now. It's about twice as big as the last picture here now.
Thanks
Hef.

I think you should send some to me for testing

It looks to be a member of the Order Gigartinales, the same order Gracilaria belongs too. Quite a few members of that group, many virtually identical in structure.
