Well after researching for a few weeks, I decided my last fish I was putting into my tank would be a Yasha Goby/Pistol shrimp pair. They made it into my tank just fine and they seemed to have settled in over the past few days. Here is my quandry, the stupid things have decided that the main entrance to their burrow is smack dab in the middle of my rock work for my tank. After a harsh scolding by me, the goby just ignored me.

Obviously, I want their burrow to be seen by me for one thing. The other thing are my clowns are both swimming trash compactors and will destroy any food before it reaches the bottom (My motto: Feed it till it's fat). Where the goby/shrimps burrow is I cannot get any food down there, even trying to manually place it.

Other then tearing my rock work apart to create an opening, does anyone have any ideas? If not, and I do have to redo my rock work, what can I do to minimize the chances of caving in their tunnels while moving everything?
