Lol! I have a pair of sleeper gobies in my rs 170. Never have to touch the sand but its a dedicated nem system with 3 nems and a large hammer. I have a dragon goby in my 50 and a cave goby in my 15, but the cave goby does not move sand.And i could have told the wife we couldn't get a diamond goby that I now fued with on a daily basis as I unbury corals lol

I wonder how much a kidneys worth? Lol
