[Killietalk] Re: moina, Japanese daphnia

Hello Lynn,
     The Moina I purchased from Florida Aqua Farms are very tiny, maybe 3 
times the size of a period. I have a tank of guppies that have what I think are 
Daphnia in it, and they are much larger, the size of a sesame seed. I said what 
I think are Daphnia because they just appeared in the tank one day. I had 
been feeding that tank freeze dried daphnia and I suspect maybe some eggs 
hatched. I have observed them attacking guppy fry, so I don't know what they are for 
sure. Looking at them under a stamp loupe, they seem to be Daphnia. Haven't 
had that problem with the Moina, but they are a bit difficult to keep from 
crashing. They need to be fed algae every day and protected against the pH dropping 
out suddenly ( maybe from too much co2 from thousands of the little 
beasties?) . Best bet seems to be to set up a new culture a couple times a week.
