Gobie and Shrimp Pair Question

[Palster]

I am thinking of getting a Gobie/Pistol Shrimp pair for my Nano tank and was wondering how much you actually see these little guys? I have had Gobies in some of my other tanks they you hardly ever saw other than at feeding time. I really don't want to add a fish that you aren't going to see much of so I thought I would ask the question.
