I wouldn't say its wrong whatsoever as most fish food has fish in it and as said already someone else just does the killing for you. How many cod get pulled out of the sea everyday and put on plates? so its not cruel to buy a frozen fish for dinner and neither is it wrong to feed live fish to your fish thats just my opinion anyway.
Yes fish have the chance to escape from predators in the wild but depriving a predator from hunting i would consider to be more wrong than using live food.
