yeah, lowcel should have said it in a different way, but what he was trying to get across was how aquanero put very well, feeder gold fish especially have almost no nutritional value being mainly fat and most carry parasites due to the poor conditions they have been kept in. if you really want to do feeders, then use something like guppies or platys and it should only be a supplement to a main diet of pellets, and they should be quarantined and treated for parasites. also i dont use feeder fish, i use insects and IMO its just as interesting to watch if thats what your going for, and you dont have to worry about them transferring anything to your fish. frozen foods, worms, mealworms, crickets, and the random grasshopper i catch outside is what my fish get but this is only a few times a week to supplement their pellet diet
