macro algae suggestions

[evil Nick]

So I had some nice colerpa (green feather), and Dragons breath, and now came across a nice piece of what looks to be brushy red.

Well my emerald crab destroyed my green feather, and my newly aquired yellow tang ripped through my red dragon breath. Neither seem to be very interested in the brushy red.

I REALLY want to have macros in my tank and was wondering if you guys could give me some suggestions and even possibly sell me clippings (if you have them) or some that nothing will eat.

I saw Maidens hair which looks great to me but heard it can get out of control. I would be willing to try it and maybe use it in a put to keep it from spreading.

Anyone know of anything else?
thanks

If you want to have macro algae in the tank, it will need to be of a type that is hard. A tang will rip apart almost all of the algae put into the system except what it doesn't find to be palatable, which are algae that are hard and borderline calcium based.
