Ocean plants with coral ?

[flobup]

just got into keeping coral, have two zoa frags, a meter shower frag and a pretty big gsp colony growing right now. I have two drawf angels in my system that really love this grass like plant that I get from my LFS. I was wondering if keeping this plant in my DT will hinder the growth of my corals ?

Probably not, but what is this plant?

I’m really not sure, the LFS guy jsut calls it sea grass lol
