I don't know anything about Fairy Shrimp, but here is a google search of PBF that brings up several links to posts about grass shrimp, ghost shrimp, glass shrimp, fresh water shrimp, also known as PK shrimp. I put some of these PK shrimp in my forage pond, but it has been a few months ago. I need to seine or otherwise try to capture some to see if they "took" and now I have a sustainable population. I'm afraid the masses of FHM I have in the forage pond might have made short work of my newly stocked shrimp. I did see some a couple weeks after introduction though. Try some of the google links and see if they are the same thing as Fairy Shrimp, or at least similar. Might give you some of the information you need.
