Best sand sifter?

[Coralgurl]

My diamond back goby sifts like a champ, but eats frozen and pellets, comes over where I feed and grabs his share. He has his area that he sleeps and I can't keep any corals on the sand in this one area as he likes to rearrange his home, otherwise, other corals are fine. Nice thing about the diamond backs is they don't create sand storms and don't move around when sifting.
