    Nice one James. I splitted the daphnia, one of them got crashed. And the other is still surviving. Havent harvested anything from it.

    Iam using brine shrimp is more reliable.

    Just a small update on these daphnia buckets. There are total of 4 buckets at 3 gallons each. The daphnia culture in each bucket is doing well with minimal work needed. They are still sitting in the patio with a few hours of sunlight during the day, the rest is shaded light.
    I top off the water with used tank water whenever I do water change. I don't feed them anything except a bit of diluted liquid fertilizer that I use for my house plants. This liquid ferts will produce green water with the help of sunlight, and the dapnhia will feed on that green water as soon as they are formed, simultaneously. I harvest once or twice a week and feed them to my wild betta fish and others.

    Each harvest.

    Just a bad quality video to show you the status of the culture.


    At the moment, I have 2 cultures at 1 gallon of water each to test out. Both are doing well in this cold weather the same as others.

    Nice bettas. I've had some chances at a few wild types, nothing special, but I was not ready for this care to breed. Have been considering some dwarf cichlids...might need to start a colony!

    That's awesome, what kind of fertilizer do you use? Plant sticks/stacks or a liquid fert?

    Do these guys prefer stagnant water or some movement ... I know too fine of bubbles can be fatal to them, but are you running a regular line without the stone?

    Micheal,

    These buckets have no filtration, no water movement, no heater. It's just standing water as is.

    Daphnia do not require aeration. Their locomotion is enough to stir the water as needed.

    However, a HMF filter, or a sponge air line filter is fine as long as there is very minor disturbance/current.

    Awesome ! Been wanting to try it but hesistant on the fact that the bucket will not be lidded ( bc it needs the sunlight to grow the algae) and it can attract pest. My place is a magnet to tiny mosquitos even with only tiny puddles around...

    A window screen will keep the mosquitos out, and the light in.

    Is it ok to raise different types of daphnia in the same culture, or will the larger types prove predatory?
