I feed at least once a day usually Moina. If there are moinas still swimming in he tank, I do not feed since I think it is good to let the fish do a bit of hunting and clean them up. I have no idea what is best since paros are new to me, but as a long time fish keeper, it seems to me that feeding can vary from everyday to at least everyother day and sometimes even less. In he wild, fish do not normally get a full meal everyday so I usually don’t worry much about constant food available…depends on the moina cultures. For breeding I think a bit more is better and also a variety of foods.
As long as water parameters remain good, feeding is ok.
To “overfeed is up to you but generally be sure they eat it all and food
is not laying around in the tank spoiling… that is all your call….since yu know your tanks and fish.
As a successful breeder I would say yoour techniques are good!!
