People comment all the time that our sand looks really white and clean. We give all the credit to our little diamond goby, who is the hardest worker in the tank, constantly sifting and transporting mouthfuls of sand from one place to another. Now that I think about it, the nassarius snails might also help some too. They work like little submarines with little antennae poking above the sandline. At feeding time, they all come up for some clean-up!Originally Posted by uriah
