Grasshoppers contain chemicals that could potentially harm fish if fed too often, along with beetles, moths, spiders, etc. If you were to feed insects as a snack, stick with the simple store bought crickets (and not the wild black ones).
All you really need, would be some larger flake food, freeze-dried krill, bloodworms, and pellets. I used to feed them feeder fish also- euthanize the fish (rosey red, etc.) and dangle it at the top of the water, and it might go after it. You should be feeding it around twice a day, in small amounts. Not a pellet every 3 days xD.
