I do sell them individually, since some customers like to raise them as pets. (So yes, selecting a quantity of 1 means one single daphnia for all those curious!) My recent accidental trial of rearing guppies with daphnia shown that daphnia become a companion instead of live food when the quantity is large enough.

They can be unisex(female only) or bisex(male or female); it depends on the water condition. When they are unisex, they can reproduce by themselves and the eggs hatch almost immediately after birth. My Discoveries: I did some tests and put 10 daphnia each in a single compartment of a 10-compartment container. Over some time, I discovered that most of them had been doubled or tripled in quantity. I used only green water (unidentified microalgae) from my aquarium tanks as their food and never changed it. Raising the Daphnia You can grow algae to feed them by extracting a part of the water from the package, and placing it in a separate container. By exposing it to LED light, it will start to grow, and you can feed your Daphnia with the algae. You could also feed them yeast, but I recommend feeding them with algae as it is easy to grow. You will see the green water in just a few days. Good luck. Condition: New, Qty: 1, Water Type: Fresh, Suitable for: Carnivores, Brand: Unbranded, Type: Live
