Can't help you with this one. I just tossed a few into a gravel bottom 46g bow front and a few months later I had about 250 of the little suckers. I do know that Jack T keeps all the fry in a floating container so they're easier to feed, collect and segregate. I don't know how he catches them in the first place.
He gave brought me some new additions last week, including some calico's, Green Dragons and Super Reds. Looking forward to growing them out...
