Do pistol shrimp pair with other fish?

[_cpate3_]

Recently added and new pistol shrimp to my system, and saw that my Pygmy hawkfish was following it around and acting like a watchman for the pistol shrimp. I’m interested if anyone has any other experiences with this happening, or other stories!!!

Hawk fish+Shrimp=prey and potential predator.
