I got a rare glimpse of my pistol/goby pair hard at work today. Normally, they skitter back into their hole the second I get near the tank. However, this time the goby kept his eye on me (never flinching), and allowed the pistol to continue working for nearly 10 minutes. The quality of the video is not great, but at the 1:55 and 3:55 mark you can see some unique behavior as the pistol clears a hermit and nassarius snail that was in the way.
Hope you enjoy this rare glimpse of my favorite tank inhabitants. My water is always cloudy because of this guy digging, but I would never get rid of this pair. The symbiotic behavior they display is simply fascinating.
Note, the first 1 minute of the video is rough, until I tweaked the zoom and angle a bit. The ability to see what is going on gets significantly better at the 1 minute mark.
