yes, it is quiet marvelious how differently you think about something when you are educated about it. you learn to see it from a different angle, instead of seeing fish as a pretty decoration you begin to consider its living conditions.
i remember this happened to me once time in a resturant, where they had an entirely empty tank with fish. sure it had light and was filtered, but no gravel, no plants (Not even fakes) no nothing. i'd sure not want to live there.
