I set up my tank with a 4" sand bed. Added lots of rock and filled it. Before I add fish, I was thinking what if a little fishy digs a hole under a rock and the whole pile tips over and breaks the side glass. Should I take out the rock and sand, then put the rock directly on the bottom to prevent digging?
Tank 30" tall. Rock is piled 18 inches tall. Or is it very unlikely a fish will dig a deep enough hole under a rock to tumble the whole pile? The rocks are solid but if the base shifts some of the rocks can roll off the top.
