I am slowly adding fish to my tank, a 69 gallon Red Sea. I have had Pistol Shrimp with Goby in the past but it was 10+ years ago. Back then I had pink Fiji sand which was very fine. I seem to remember my Pistol Shrimp making havoc in the tank by constantly digging new burrows all over the tank and on occasion bury a coral. They are really cool to watch though so we have thought about that being one of our additions this time, but I am also reserved about it. Are all pistol shrimp species equal in the amount they burrow? Have you ever wished you had not introduced one into a tank?
