I have a daphnia culture; it's going very well

The daphnia culture originally came with cyclops which I've separated to a 2 liter coke bottle. I left it alone. They seem to be surviving. I separated them because I've read that cyclops will attack daphnia and small fry. But I've my doubts. A few daphnia is surviving amidst a huge crowd of cyclops.

I want to use the cyclops as live food. What I am afraid of is that the cyclops might overpopulate if my fish aren't interested in them or that my fish aren't fast enough to catch them. I have guppies, cories, and a pair of cherry barbs in my tank. Can I use cyclops as live food?

If unsure, whip the fish up in preparation for feeding (do whatever you do to let them know food is coming) and then offer a small amount of cyclops to determine if they are interested/able to eat them. They are shelled, but anything that is mouth-sized should be fair game.

I wouldn't try them for fry food.

cichlids like cyclops.
