I have had a "Diamond Watchman" sand-sifting goby in my tanks for over two years. He has doubled in size and is one of our favorite fish. He makes a mess while he first arranges the sand the way he likes it, but the mess settles down after a few days. He does keep the sandbed free of diatoms, cyano and other issues. Just nice and white, the way we want it. He keeps the sandbed well-oxygenated.
Others to look at would be the orange spotted goby, sometimes called orange marked or orange line goby.
