You all should get off your high horses. We all keep fish in our tanks that don't belong there. So just because this guy is a moron does not make you somehow more humane than he is.
I could never eat a shark, their too amazing in my eyes.
I just don't get how ignorant someone could possibly be to think they could keep a shark, and even then a black tip. Maybe not the biggest of sharks but still, its inhumane for such a beautiful creature.
In saying that I believe no creature we keep in an aquarium is better off than it is in the wild. The idea we are providing them food/protection (Which I'd argue we do not protect them as many get sick or beat to death, or give them their natural food source) is a BS standpoint. While we all keep fish we should not try and convince ourselves we are doing any of them any favors.
What does this mean? I/most of us keep nothing in my/our tanks that does not belong there...so, yes, it does make us more humane...most of us consider our tank sizes, fsih size, growth rate etc BEFORE adding any new live stock...a few do not consider tank size, fish size, growth rate, etc. and that is why you end up with a black tip in a tank that is way too small...that is not cool...
