Starchick- IMO...Anacharis gets eaten QUICK normally and Im not really sure of its nutritional content; but have done both for my Res. I would think since the anacharis goes fast (and it is NOT nutritionally complete as lettuce; vit A etc.) that the green veges should still be fed daily. Or as long as your turts are hungry!
Someone who has does something else may come around soon and let you know what they think!
This is just my opinion and what I do with my res....
