easy food culture

I currently have black worms living in my Elassoma tanks, but in one tank they seem to be stripping all the leaves off of my bacopa. There are a whole lot more worms in this tank than I had thought.
I have daphnia living outside in tubs of green water, but not getting the large numbers I was hoping for and cyclops seem to always find their way in which I have read kill daphnia.
I do not get enough cyclops to be a constant food source.
What else can I grow in my tanks to keep them in a food source?
This particular tank is also being overrun by least killies. I am eventually going to separate them.

I am sceptical that blackworms are damaging your Bacopa. I suspect something else is hurting it, and the blackworms are just in the wrong place at the wrong time.

Have you considered rotifers? I have not tried to culture them myself, but there are tried-and-true propagation strategies out there. They are raised extensively in the aquaculture industry to feed larval fish and invertebrates.

Yeah, it occurred to me that it might be snails or ? and the black worms that are all over the plants when the lights are out just look like the culprits.
I am interested in culturing rotifers. I googled it, but did not get the info I was after. My time is short today...
I will check out this book.
Thanks

I feed my daphnia yeast, i fix up three teaspoons of yeast in a gallon jar and add two tablespoons of sugar, stir it up good in warm water and let it sit two or three hours and pour it into my daphnia tubs. Seems to work really well and I get lots of nice orange daphnia.

Ah, I had read about feeding yeast and put some yeast in the container and all the daphnia disappeared. I did not mix it up and let it sit. Maybe that's the key?

How often do you feed them?
Mine are in greenwater, so I am not sure if I should be adding extra food or not?
I do grind up fish food into a powder and give them that sometime.

How long have your cultures been set up? I feed mine even if the water is green but you have to be careful about the water fouling. If it begins to stink I drain away 50% or more of the water and replace it with clean water. I doubt they are eating the ground fish food, it might be generating bacteria they can eat but be careful, if the water fouls the daphnia will not do well and may die. I usually don't harvest until the culture is heavy with daphnia and I take care not to harvest more than a small fraction of the daphnia at one time, maybe 25 to 33 percent. I feed after harvesting. Which daphnia are you growing? Daphnia magna can be harvested by only harvesting the adults with a regular green mesh fish net...
