What kind of grass?

[Ray]

Widgeon Grass and Feather Grass is almost the same.
Feather Grass don't have white root stalk and is a lil more brownish leaf.
Widgeon Grass is Green with white stalk above the root.
From that picture, it looks like Feather Grass, but it is kinda hard to tell.
Feather Grass does better in brackish/salt water.
