Anyone carry live Red Gracilaria/Ogo for tangs?

As the title says, looking for lfs in SA who carries live tang food on a regular basis.

And I'm only interested if it is kept completely separate from your fish system. I'm not doing a Quarantine on my veggies.

Tagging along to see if anyone has it.

And if the variety is known, please post. I've tried one type that they won't eat. It's pretty though. :)
