front loading sand by goby
hey guys -
my goby has been busy burrowing, and the dust has finally been filtered out from where all he was digging; but i've noticed that he has moved a good deal of sand to the front of the tank and the back is getting a bit bare. i moved some sand around and also moved my rocks to prevent any rock falls, but am curious how yall deal with it? and the sand i moved was stuff he has sifted and keeps turning around, so it wasn't the deep layer of sand that was messed with.
