So, I have had this pistol shrimp for over a year, with yasa hashe goby. I have never seen him more than 6 inches from his burrow. Well this morning I saw him do 3 laps around the perimiter of the tank, and even swam about 1/2 way up a couple times. Think everything is alright? Was he just antsy? Spring fever? I would love it if he did that more often.
