so i guess it rains pellets in the amazon everyday... what goes in the feeders goes into fish. if you feed high quailty flake, pellet, ect for about 2weeks getting your feeders nicely gut loaded you will be fine. dont even bring up "Oh well feeders blah balh give your fish fatty liver disease". since when has a fish lived long enough to get that???? if it happening your fish would die of old age insted of fatty liver. feeders should be the 3rd choice if all else fails or if your tank/pond is to big for your fish to even find the food. should be 1st pellets/flakes 2nd freeze dried/frozen 3rd feeders. i have gars & channel cats feeding perfectly on rosys, mosquito fish, guppies, goldfish, and freeze dried shrimp. Growing rapidly and strong still.my florida gars are growing rapidly along with the channel cats and are PERFECTLY healthy. so the statement your just purposed is false.
