I have collected white pistol shrimp, different sp then the one listed on saltwaterfish.com, but looks similar. I prefer the colored up ones, there are red, yellow and my favorite is yellow and red striped. I keep a lot of shrimp, but I don't have any pistols as IMO they hide too much. I did however just set up a 54 gal pie shaped tank for some macro algae and one of the things I want to put in it is a pistol-goby pair. I know a place where there are lots of pistols that share their burrow with siminole gobies. Not the prettiest, but ones that I can collect as a pair.
