I now have two tigertails in my tank, not quite sure where the second one came from, I only recently noticed him in there. Together they work all of the sand, to the point that they move it into large piles within the rocks leaving some of the bottom partially exposed with no sand; I have to then go back in and move the sand to cover the bottom again. they are not always seen; but they are working.
