I've had a watchman goby for roughly a month now (paired with a shrimp), who rarely ever comes out of the burrow (when he does come out, he stays out all day, and nothing really scares him back in). Would getting another gobie help with keeping him outside the burrow? Also the burrow is underneath barnacles, which don't allow a lot of sand to collapse back into it, so i rarely see the shrimp either.
Any advice?
