gore? about as gory as a Big Mac.....love my fish but i'd chop their heads off if needed!
As a vegetarian I would agree with you on that.
lol, as a fellow vegetarian I was just thinking the same thing!
The purpose of pain as I understand it is to try to make you realise that what is happening is damaging to you and make you want to get away from it/stop what is happening. It has to be painful and horrible to invoke a quick reaction out of you and get you to protect yourself. It is a kind of biological preservation measure I think. If any species ever evolved without it, I'm pretty sure they would have become extinct pretty quickly. Therefore I would think that fish must feel some kind of pain for so many of them to still be around and for them to want to get away from what I would consider painful situations the way most of them do.
Maybe they don't feel pain in the same way that we do or with the same intensity that we do, but they must feel something unpleasant as a survival instinct. If you can get close enough to one of you fish to stick a pin in it, it would swim away quickly because it has felt something it doesn't want to feel. Whether it comes in the realm of discomfort or pain I don't know, but I strongly believe it is there.
