Yes, this is exactly how I do it, too. I have an extremely long plastic pipette and feed very small amounts og BS naupli under the catappa leaves where the paros like to hang out. Any surplus naupli from a hatching is evenly distributed in all my cory tanks. They go wild 🙂
I now have a good culture of Moina naupli to harvest, too. Breeding them is even simpler…fresh water, no air, just light and food. And they live on in the tank until they’re eaten. I use exactly the same pipette method, and the Moina naupli tend to swim near the bottom…very convenient !
