Default Daphnia Magna ...

My small P. Gertrudae rainbows are too small to eat my adult Daphnia Magna that I've been culturing. I'm getting some Monia soon, which should be more appropriate.

If you want to try your hand at culturing some Daphnia (and want to pick it up--no mailing), let me know. You'll need some old aquarium water in at least a gallon container of water. No heaters, flltration, or air of any kind needed. Just feed a pinch of yeast or baby food (sweet potatoes) mixed in water.

Fish love these things. They're pretty cool, too.

(I still have Cherry Shrimp, too, at $1/each.)

So just some old aquarium water and they'll grow & multiply? I had a daphnia culture once and couldn't keep them going long on just yeast.

I might have to try it again someday. How big is the tank you're culturing them in?

I have an outdoor 10 gallon that houses many ostracods and daphnia...

It has no filter no electric light no heater plants and cherry shrimp and tons of snails....

I have never added anything but the plants a few snails and the cherrys and they all made it through the winter......

Im not familiar with what kind of Daphnia they are but they are about the ~1mm around and lighter colored....

I thought it was an amazing thing to watch with the whole little "bio" thing going on in a stagnant water aquarium. I never thought that the whole thing would last through the winter as cold as it was.......

I've had the best luck with the swwet potato baby food. Yeast gave marginal results.

I grow them in several large plastic kitty litter containers.

I'll probably take you up on your offer for daphnia next weekend or whenever I can find some free time.

Live food for my fish is always a good thing.

I used to culture this stuff. Don't use dogfood. I got lazy with the yeast/fish food mixture, and started using dogfood. Without aeration, dogfood made a layer of crap on the top and killed the culture. Now I don't have any... They were so cool too! Gotta get me some again.
