Yes, they sift the sand, but only until they are done making their tunnels. A better sand sifter would be something like a dragon or a diamond goby perhaps. If you want something that looks like an eel (which I just read that you are looking for from your other thread), go for the engineer. You should have at least a 70 gallon tank though, because they get huge. And you should have a relatively deep sand bed to keep them happy.
