I have a 32.5 gallon mixed reef tank with 2 clowns and 2 bangaiis. I really want a Goby pistol shrimp pair. I am thinking about getting a Yasha Goby and a Randal's Pistol Shrimp. I did have a couple of questions though. Does anyone have a list of gobies that you can pair with Randal's pistol shrimps? Do you have to put a dish of sand in a quarantine tank for them? What does the pistol shrimp eat? Any recommendations or suggestions on anything with them would be greatly appreciated! Thank you!
