Randall's pistal shrimp & Black ray shrimp goby

I have a black ray shrimp goby which I love (Stonogobiops nematodes). I
plan on purchasing a Randall's pistol shrimp for this fellow (A. randalli).

I am interested in this pairing because I think I would enjoy having the
appropriate shrimp this watchman goby exclusively bonds with in the wild,
and I have heard that S. nematodes is often reluctant to bond with any
other species of pistol shrimp.

I would like to hear some personal experience with this pistol shrimp
and/or this watchman goby. I have heard from some sources that A. randalli
is a particularly shy shrimp and I may not get to see it very often. Has
anyone had experience with S. nematodes readily bonding with other, more
visible pistol shrimp?
