Daphnia Help

Hi everyone

We've got a pond outside with no filter or fish. Basically just a tub of water with plants and algae. I caught something fro the pond today which I think is daphnia. I plant to feed it to the fish.
Are there any bugs which look similar to daphnia and can harm fish? I'd like to start feeding my fish live foods but I really don't want to harm them.
Also is daphnia good for fry?

Thanks

 

unlikely its harmful. if it's tiny white specks; then probably daphnia and good for as a feeder

 

Thanks Kasshan!

 

i went down to a local pond in central california myself and collected the some samples to seed my tanks with micro orgs, like daphnia, when i restarted the hobby 5-6yrs ago

 

Cool. How do you keep daphnia in captivity?

 

I would like a but more information on seeding a tank if you have a moment? I would love to seed a Scarlet Badis tank.
