I'm thinking about getting a Randall's goby and Randall's pistol shrimp. However... When I set this tank up, I didn't think to place the rockwork on the glass and instead placed it on top of the sand bed. It's a very stable structure, but I'm still worried that a pistol shrimp might cause the rocks to collapse.
Any thoughts? Would a small shrimp like the Randall's do enough digging to cause everything to collapse? Perhaps anything I can do to secure the rockwork without removing it and rebuilding it on the glass?
