When farm raising Fathead minnows, after the minnows spawn is it necessay to seperate the adault breeders from the new hatch, are they a canabalistic? I want to build a pond to raise Fatheads as a feed source for my larger pond. Any help is appreciated, Thank you!

I've raised fathead minnows myself, and have found that they are extremely fond of pelleted feed. In the pond they were raised, I never separated the adults from the fry and it didn't prove to be a problem. They are so prolific, that even if there is a small amount of cannibalism it would prove to be insignificant, especially if there is a lot to eat in the form of pellets.
