Here's a quick clip of my paired yellow watchman goby and tiger pistol shrimp. I originally bought the two together but while in quarantine, the goby died. So the shrimp was in the tank by himself for a week or so while I got another YWG. Put the goby in the tank today and they paired up right away.
The shrimp had already made his hole before the goby and didn't make too much of a mess. Now that the YWG is there, the shrimp is messing around with everything. For a little shrimp he's pretty dang strong, picking up frags etc... We'll see what happens but hopefully he will settle down a bit when he's done building.
