The following is cut and pasted from the aquatic plants forum on the topic of moina. Moina sounds like it has good possibilities as a live food for apistos (which is why I have been trying to locate some). beginning of paste: Mike Variano wrote: I know this ins't the right place for this question, but with all this talk about green water and daphnia I had to ask. Does anyone have or know where to get Moina? it's very similiar to Daphnia, but has lots of advantages. According to my microalgae culture manual anyway. Hi Mike! A friend of mine once cultured Moina. He kept it solely as a fish food. I'll tell you, I have never seen fish in such beautiful colors as was his. It is well known fact Moina poseses the highest protein content of all commonly available and cultured critters. There are several advantages of raising Moina as opposed to other Daphnia varieties. One of the most important is surely abundance of proteins(75% of dry matter)and amino acids for which we know are not stable and usually break down within hours of the death of the host (daphnia) in our case. Resistance to extreme temperatures is another (it will do well from 5 to 35 degrees Celsius).In fact one can easily keep them in the fridge for a few days. They will be just fine perhaps a bit hungry :-) that is all. There are other advantages which I can elaborate on, if there is more people interested. I have heard, that more and more commercial fish hatcheries are using Moina as opposed to brine shrimp. Since I moved from Vancouver, I have lost contact with the above mentioned friend, but I'd love to get my hands on a small culture.
