Just put a Filter on the tank for a while. I do know what you mean, mine has reshaped about half my substrate. Then my Phosphate went sky high and and my Nitrates followed along. It has been fun.
Brave soul. When I went down this morning I noticed a big pile on the left side of my tank, that bugger has been fine in the middle under some rocks with I believe 3 outlets, so at least 3 tunnels. No that's not good enough, lets head on over to the left side and and do some redecorating. I thought my Goby was bad when I had him.
