Just because that may be true for you, does not mean it is true for everyone. I get much more enjoyment from the scientific aspect or fish keeping than the aesthetic aspect (although I enjoy that, too). Fish keeping is much more to me than just arranging stuff inside a glass box to make it look pretty (if that is the only reason you keep fish, then what inspired you to get into fishkeeping rather than something else, like flower arranging?). The things I like most about this hobby are observing the fish's behavior and how they interact with eachother, learning about different species just for the heck of it, and learning about chemistry through first hand experience (as opposed to just reading a book about it, or something). And judging by the number of votes for "Science," I'm pretty sure I'm not the only one who feels this way.
