over the years, I've had so many pairs of these...a nano is almost not complete without them in my house.
In a small tank, they almost always find one another...though sometimes it takes a week or two it's usually near instantaneous.
In larger displays, I have just used a well positioned weighted cover, like tupperware to keep them together until the shrimp builds his burow and the goby joins it.
Keep in mind, LFS often charge more for a symbiotic pair than for 2 individuals so depending on where you get your info, there may be some bias.
