B Bug,
I am sure we have some experts on the forum about breeding and raising fish in tanks. However, I do not typically see much discussion in that area on Pond Boss.
However, I do see a lot of discussions in the aquarium forums on those topics. I have read discussions on how to get the broodstock fish to successfully spawn, how to feed the fry, when to separate the parents (or other adults) from the fry, etc.
Perhaps, you might have more success if you tried to copy their methods and scaled UP to your tank operations, rather than trying to scale down the "pond" methods of raising forage fish?
Good luck on your project! Also, if you do mostly follow the "aquarium people", I believe many people on Pond Boss would still love to read about your results and offer suggestions, improvements, etc. And of course, learn from you.
