Hey all I wondering what in your opinion is the best feeders for native fish. I have two Redfins now and I plan on getting a chain or northern once my DIY tank is finished. I try to keep my selection to fish that are only native to their natural habitat. Right now I feed mainly fathead minnows also called rosy reds (same fish species however some hatcheries have bred for the red gene) also small crayfish from time to time. My main concern is I have read conflicting reports of using fatheads as a staple of their deit. Some say it's great others say they are to high in fat. Another option which I have not done is tadpoles. I would think that they would be high in some very essential nutrients. Frog's are a staple of many fish diets so one would think tadpoles would be of the same benefit in the aquarium setting. All my feeders of course go in a q/tank for three weeks prior to consumption. I keep all my feeders on a healthy deit alternative the foods they receive daily to maximize nutritional value. They say you are what you each, so what is everyone's thoughts and or suggestions?
