Oh, my mistake. It's OK for them to eat small fish in the wild, but if we feed them "feeders" (and I don't mean feeder goldfish, there are other "feeders", saltwater included) then we're evil evil people.
I'm sorry, but I fail to see how that logic makes ANY sense.
I see your point from a nutritional standpoint, and agree wholeheartedly with that. I was assuming that the saltwater predators were being fed things they would eat in the wild - you know silversides and other small "baitfish". But, I fail to see how watching them eat is somehow evil and wrong. If you don't want to see your big fish eat littler fish (exactly what they do in the wild) then get smaller nicer fish, ot don't watch them eat. I like to watch them eat - it's fascinating. And I can't fault someone else who likes to watch them eat.
My point was that watching them eat is not evil and wrong. It can certainly be fascniating. Watching an animals behavior and even how it eats is how many scientists have come to understand many creatures, not just fish, in the world. Isn't it the poitn to not only keep fish but to learn more about them? If we don't watch them eat, how well they eat, how often they like to eat, and what they prefer to eat, how are we supposed to know what to feed them? Sure, there are books out there, but how do you think the people who wrote those books found that out? They didn't just wake up one day going, "hey fish like to eat other fish" - I'm pretty sure about that.
I'm sorry, but some fish are natural predators. If you don't want to see a predator do it's job, then don't keep them in your tank, or don't feed them live food. Some of us like to watch them eat live food and hunt it, provided it's good for them to eat.
That's my opinion on the matter.
