What Macros should I add?

[mrsaltwaterguy]

Hi all,

I'm looking to add some macros to my display tank to act as hitching posts for my seahorses. I currently have zoas in my tank and I don't want the macro to grow rampant. I was thinking of adding dragons breath, any other suggestions?

Halimeda would probably be good - tough macro that forms in coin sized links. Good for graspage. Ive never kept seahorses as a forewarning! Red macros tend to like iron supplements. Despite metabolizing quickly im not sure how horsies like iron.
