They like to have a clear view on their surroundings.
The shrimp itself is not very picky. It will dig it's burrow wherever it finds the right gravel and supporting rock.
Without a goby the shrimp doesn't care too much about where the exits are as it will be mostly night active and rarely leave the burrow.
