LOL, YES detrivores. They are things like nassarus snails, bristle worms, conches, ect. Critters that burrow in the sand and shift it around. There are sand shifters and sand sifters. Don't buy things like sand sifting stars. They consume every beneficial critter in the sand before starving to death, yet they can be bought in almost any LFS that sells salt fish. Look on this site for a detrivore package. It may also be under clean up crew.
