I hear this topic come up often about minnows and gold fish not being health for fish, and granted a fish food like Massivore has suppplments that enhance the fish health and color I'd assume, but has anyone actually had issuse they could prove was the fault of goldfish or minnows killing their fish? I only ask because I have been rasing fish for many years ( probably more than 75 % of people on here) and have even breed a few dfferent species in my time and have never had an issue with bait store minnows or pet store goldfish. In fact I have run across some of those fish that would only eat live feeders and grew to great sizes and live for years this way. So where does the idea that they are not health or have no benefit for your predatory fish come into play? After all, it is natures way for recycling itself.... Some one school me on proof of this nutritional value or lack of should I say, as well.
Now just for the record, I do feed fish food because I believe it has some vitamins effects, plus it cheaper than buying feeders every few days....
