    Well…any tips? I was considering keeping the little crustaceans in two or three 3.78 litre/1 gallon jars with plants and putting a small handful of hay in once a month…the hay’s decay will produce bacteria and protozoans the daphnids should readily eat. Once a week I would perform a 25% water change on the jar, and the daphnids harvested during this would be fed to the paros (as you may imagine this would work best if the jars are not harvested on the same day). Would this method work well?

    Oh … at the moment I have given up Moina …. My last try was a disaster … The first time I had them, they where o.k. But they are rather precarious….
    At the moment I have a try with caridina parvidentata in the “society tank”. They are said to be very fruitful. But not for breeding tanks, because they shall be also very keen in hiding … At the moment I see nothing of them. After a while I will take out the Java moss in that tank to see …

    This subject has been discussed here many times, – and I think theres a lot of information if you searched forum. Also theres an article in our link section in english (look under live food articles, theres one on dafnia)
    I too have for the moment given it up, its possible, but I think there are many different ways, and each person seems to find their own way in which they are able to keep the cultures for at least some time.
    My own experience is that you need to be careful not to use tap water, but use aquarium water. Then lightning is important, as well as regular change of water (not tap). Then its really difficult to say what is the right amount of food, – I always use yeast, – I have tried many other things, – but yeast seems to be the one working for me.
    Hay 🙂 .. well, it may be theoreticly true, but I think it will not work in this kind of setting, – a culture of dafnia will not get enough food from that, – and also, in my experience it will make it really difficult to seperate dafnia from all the hay stuff when you want to use the dafnia.

    But again, – look around here, or other places on the internet, – it should be possible to find information about it.
    And then of course, I think theres quite a difference between dafnia (ordinary) and moina. Moina are real difficult. What I am talking about here is Moina.
    Ordinary dafnia, I have that in large containers in my garden, and I do nothing to feed or change water, – that is all done by nature and works quite well.
    But moinas are a different thing

    If you want to read about culturing daphnia try going to the American Killifish site. I believe there is a great article including the photos showing the culturing setup. The hobbyist lives in Florida (year-round warm weather) and the setup is outside and maintained year round. Sorry, I don’t have the actual link to the article.

    Daphnia not such a good idea, then? OK. Any other suggestions for an aquatic live food source? (Anything terrestrial, like grindal worms, will get my parents upset…I am already hatching brine shrimp but would like an additional food source for the winter months where I can’t culture mosquito larvae)

    You can feed them with yeast and algea water or ¨green water¨ as we call it around here.

    To obtain said water take a clear container with at least a good part aquarium water.

    put in a few drops ofr coffeemilk in it (teh stuff that coms in those litle cups. Put it in a sunny place maybe use an airstone and wait for the magic to happen.

    You can also use bloodmeal a single grain of the stuff usually is. sufficient.

    we (my brother in law and i) always used aquarium water. However you coul duse part aquariumwater and part tapwater depending on where you are. In large parts of the world that si not a good idea over here it can be done due too the high quality of Dutch tapwater.
