I disagree with that. Some people simply throw in the feeders for entertainment. Whenever there are customers around the LFS
around here likes to throw some small goldfish in the oscar display just to have the people watch and they like it, which motivates them to buy an oscar themselves.
I believe feeders aren't very humane...it seems you're not doing the best for both the prey and predator. The prey is probably sick and lethargic from poor housing conditioins unless you raise them yourself. The predator will eat this and in turn will get the disease. It's like giving someone moldy sushi. They'll get sick and you're putting fish in pain. It seems more cruel than natural.
edit: Also wanted to add that sometimes feeders isn't always a good thing. Feeding feeders to arowanas all the time can possibly give them a condition called drop eye from all that protien and fat, and as they say, the damage is done.
