A comparison between cyclops, baby brine shrimp, and daphnia would be very interesting. How do you intentionally culture these large cyclops? Can they be collected in natural watercourses like daphnia in their natural range? Tom >> Tom- You culture them by feeding them infusoria (paramecia and such) I had a friend once had them take over a five-gallon daphnia tank that he was feeding Roti-Rich. THey continued to thrive on that diet, so they must be capable of filter-feeding. Yes, they can be collected in standing water all over the place. Seasonal wetlands that are wooded tend to be one of their favorite places. They return with the spring thaw each year, so I guess the eggs must spore when they dry out. Bob
