Need suggestions for a sand dwelling fish

[mdelp]

diamond goby is my favorite fish I have. If you don't mind occasionally blowing the sand off your corals and LR. my sand is always white and i never have to clean it.

oh good, feeling better about my purchase, and someone (I'm assuming the diamond goby) cleaned all the sand in my tank today so it's looking good! (there were interesting criss crossing patterns of tracks in the sand, is that the work of a Goby?)
