Without the benefit of a microscope, I really don't know if what I am doing 
makes sense, but.....

I have been

    * dipping a BBS net several times into my daphnia culture,

    * putting the contents into a small amount of culture water,

    * running that water though a doubled standard green fish net, to seive 
out the daphnia. These get fed to adult fish.

    * taking the water that remains and putting it in with fry.

The hope is that they get baby daphnia and other infusoria from the daphnia 
culture.

There does seem to be some biomass in the net.  No idea if I'm  wasting my 
time here, except that very tiny gourami fry seem to be surviving and 
growing.  But maybe they're just grazing on the fauna in the  java moss.

I need a microscope.
