I have been catching a freshwater shrimp in a local pond, (Winnipeg, Manitoba). They are grey, about 1/5 of an inch long and swim very quickly. The fish love them. Does anyone have any insights into what these are. I think they are? I think they are fairy shrimp but I have not been able to confirm this. I would also be interested in tips for the care of these shrimp. They appear to feed on algae on plant leaves. Thanks in advance. Bill Hamlin
