Could it be, that the water was too warm? My Daphnia reproduce best
below 22 oC. Ceriodaphnia, on the other hand, do better at higher

I have conducted an experiment: In one of my containers Ceriodaphnia got
contaminated by Daphnia. Instead of discarding the culture, I just let
"nature take its course". During summers Ceriodaphnia held the sway, but
in winter the Daphnia came to the fore. It was interesting to watch!
