Pistol Shrimp/ Goby

[Scubadiva7]

This is my very first post.. Bear with me.
I have a 20 gallon fish tank that I call my 'nano'. It has live sand, a filter, live rock and a tank on the side with water.. I inherited them as a gift. I will find out more about what other equipment I have. It use to be a seahorse tank then was broken down and now its a live rock tank BUT I want make it more. I was wondering what gobies go with the pistol shrimp. I think its just so adorable how they live together and dig the tunnel home together. I am not in a big hurry because I need to learn alot first. Any comments would help. Also, I live in the Phx area and was wondering how reef clubs work. Anyone in the region or know how the forums on here work to find more out.

also, the pistol shrimp have diffrent species, like randals and tiger, the two that pair w/ gobies the most. dif. goby species pair w/ dif. shrimp species, like the YWG pairs w/ tiger pistol shrimp. and the high fin red stripe goby pairs w/ the randals pistol shrimp.
