Duck weed as food?

[swatsx]

I have a Russian tortoise, and a alligator snapping turtle, in my AST tank I have duck weed, this stuff grows like crazy. Anyway could I once a month or so feed the extra duck weed to my Russian ?

According to the Tortoise Table Duckweed may be fed in moderation

Duckweed won't hurt the tortoise, but is a higher protein, very low fiber food, so not a good tortoise food.
