Well, I did some narrowing down. Doesn't seem like I did, but I'm also taking into account availability, so if one species isn't available, you'll see a similar substitute, especially with the macro algae. I also took into account whether or not the algae is edible, so the urchin won't bother it. I'll grow some edible stuff in my refugiums so I can feed him.
I still want to name him. He needs a fun Pirates of the Caribbean name.
Halophila decipiens - short seagrass, thanks Tom for putting it in your tank, now I want it.
Halodule wrightii - tall seagrass, resembles vallisneria a bit
Halimeda incrassate - A Halimeda for the substrate
Halimeda opuntia - A halimeda for rockwork
Padina - very cool brown macro, looks a bit like some terrestrial mushrooms
Dictoya - brown macro algae, more fragile than the others
Chondria - red algae, fine texture
Gelidium - more leathery, and fernlike
Thanks for looking. With the color of the rock, I'm not even sure I want a red macro anymore. Anybody have any thoughts?
