This is my favorite post thus far. I had no idea being munched by teeth in the throat and tongue was quicker and less painful than being munched by incisors. I'm sure it would be news to any feeder fish as well.
Congrats, you've officially gone off the deep end. Seriously, you're just being ridiculous. Are people a primary food source for bears? No. Are fish a primary food source for other, larger carnivorous fish? Yes.
And I'm sorry. Whether or not a feeder gets chewed to death by the front teeth or the back teeth - a difference to the feeder, it makes not. You can freeze or gas the little guys all you want, but if they suffer by being eatin while alive, they're gonna suffer as they're being frozen or suffocated. And ipso facto, if they're not gonna suffer from being frozen and suffocated, then they're not gonna suffer from being hunted and eaten.
Look, I'm against animal cruelty just like the next guy, but you people who seem to think that if a predator eats another fish in the wild, it's somehow more noble than one who eats a fish in a captive tank, are in a league of denial I've never seen before. And you keep coming up with these same moronic arguments: the fish was too big, the fish should be frozen first, no creature should kill and eat another creature ever, it's not fair, the piranha should only be able to chew the goldfish with his back teeth (my favorite), the fish should be from a grocery store and cleaned and diced before throwing it in the tank, the fish should be ground up and formed into pellets first, it should under no circumstances be recorded... blah, blah, blah. Can't you see how crazy you all sound?! Fish eat fish. Fish will continue to eat fish well after you all are dead and something is eating you. Get over yourselves and go watch your fish swim.
