I have no objection to eating tropical fish as such. It's just that it would hardly be a very economical proposition, given my large expensive tank and tiny fish.
As for being fond of your animals and eating them- that is a dilemma that farmers have had to deal with for millennia. And before that hunters often got emotionally involved with animals they were pursuing. It is not just about exotic travel and different culture- there are still farmers in the UK and the US, and some of them probably get quite fond of the piglets they are rearing. People's horrified reactions do seem to me mainly a sign of how far urbanism has been carried these days, to an extent where most of us are happy to eat meat, but relatively few can cope with the idea of animals being killed.
The idea of eating a living animal for a dare seems to me in dubious taste though. I think there is a strong case to be made out for the kind treatment and humane killing of any animal intended for food.
I was raised on a farm, and have both witnessed animals been killed as well as killed them myself, so this is my take on things as far as the farmer and animal relationship goes;
From a young age, i kept miniature bantam chickens as pets- i kept both hens and roosters.
When a hen raises her chicks, and the chicks eventually mature into adults, a lot of the time at least 60% of the chicks mature into males.
This is a problem because roosters can be quite vicious to each other, particularly when there are few hens to go around, the roosters can also be particually aggressive towards the hens as well (like guppys, if there are too many males to the female ratio, male guppys will not only become very agressive towards each other but will also over-harass the females).
The second problem is that you don't want the chickens to inbreed with each other, which they will often do if both brother and sister hens are raised together.
The third problem is that male roosters do not enjoy being on their own or only in the company of other males, they literally become depressed or will even sometimes try to rape each other, so you cannot really keep male roosters in all-male groups or on their own when they are fully mature as they will not be happy this way. It is possible to keep young roosters together, but this is only really a short term solution.
So obviously you have to do something about the male roosters. Like many farmers raising relatively small quantities of chickens, we killed and ate the excess roosters born once they matured.
The system i had was to have 2-3 mature male roosters who were not genetically related to the bulk of the females, and these particular roosters would not be killed/eaten. The male offspring from these male roosters and hens would however be killed to prevent the problems listed above. Hens would never be killed unless there was an extreme excess of them.
It is generally advised to have at least 4-5 females per rooster, although we often had far more than this (usually 10-20 females per male). During much of the year, the roosters spend their time trying to impress females to persuade them to join their group of existing females (they will try to impress females by fighting other roosters, finding good nesting sites or food for the females, or simply by displaying their good looks in front of the females).
Young females in particular will often spend a lot of time going from one males group to another- young males usually don't start building up a decent group of loyal females until they are a couple of years old.
All of the chickens were completely free range- they had a pair of joined ex-cattle stables they lived in, but the stables were always open to the chickens to go in and out of as they wished (the door for the chickens to go in out of opened out into a pen, but the pen fences were designed so that foxs could not get in, but the fences were short enough for the chickens to fly over).
The chickens never strayed from the farm and always came back to the stables on their own accord every night when they choose to, so i am sure they enjoyed living on the farm otherwise they would have simply run away.
We killed the roosters by ringing their necks i.e. by breaking their necks, which is a humane form of euthanasia which kills the chicken pretty much instantly if done correctly.
And like my brother and mother, we ate the chickens that were killed on the farm.
Its difficult to describe what it is like- you see the chicks hatching from their eggs, you see them wander their first days outside, you see them go from the cute fluffy stage to the scruffy-looking teenage stage where their fluff is replaced by feathers, you see them mature into fine adults and court their first partners etc.
But one day you kill them, you see their last breath as their body goes limp, and not long after, they end up nicely cooked on your plate with some vegetables, and you enjoy eating them. You give the leftover bones for the pet cats to eat, or make them into a stock, or simply put the remains onto teh compost heap to be turned into fertile soil etc.
Many people here i am sure could not posibly dream of eating any animal they knew, however i did and i felt no regrets over doing such a thing.
Perhaps it is because you know that the animal led a good life, and was killed humanely, and that its meat was not wasted. You know that it is the cycle of life- you understand that as a human being, it is just as natural for you to eat meat as it is for the chickens to eat caterpillars or worms.
You can appreciate that animals life, and know it lived well in the time it spent on this earth, it never had to fear predators or fear starving to death or dying or horrible deseases etc. Its nothing personal between you and the animal, yet at the same time it is.

Anyways...
I think its a shame how distanced so many people are becomming from their food. Its also because of this distance that people allow (and often don't think of) such farming attrocities as battery, intensive, 0 grazing etc types of farming (which are horribly inhumane and offer the animals a very cruel quality of life, also needless to say, the products produced from these farming methods tend to be of poor quality and not environmentally friendly at all.
Hundreds of good small farm 'farmers commit suicide every year due to the hardships these mass-produced farming method farms impose on them, lowering food prices to levels too low to posibly compete with. The ill animals these immoral farms often produce often spread deseases like cow TB which are becomming all too common for most good farms to cope with.
Perhaps we should get back in touch with our food, and learn what exactly it is and where it comes from, how it lives, how it breeds, and how it dies? I think so. Some children now days do not even know that milk comes from cows, instead they assume it comes from cartons/bottles. The object is not to humanise or de-humanise animals, the object is to appreciate/respect them and what you eat.
And back to the fish eating debate- i don't have a problem with it in general with my other points taken into consideration. However i would advise that if you decide to raise aquarium or pond fish or critters, you should avoid losing compassion for them completely, but at the same time do not allow yourself to become too emotionally attached to them etc.
I would also advise anyone deciding to raise their own food to learn how to humanely kill it- killing an animal humanely often takes at least a certain degree of skill and knowledge. If you cannot bring yourself to chop off or bash in a fishes head, or do not know how to do it efficiently and quickly, then raising animals which you yourself will sooner or later have to kill is probably not for you unless you come to terms and learn these things, or find someone experienced and skilled to do them for you.
