The first fish-keeping was practiced by cavemen who wanted to supplement their hunting and gathering diet with a constant food source. Lack of aquarium heaters posed a problem during the Winter months, but led to the invention of the first TV dinners. While maintenance was time-consuming, these pioneers discovered that keeping and breeding increasingly fancy and colorful fish would impress their wives and get them laid, which was the foundation for the hobbyist fish trade we know today.
When considering entering the fish hobby, you must make special considerations regarding equipment selection and placement. Fish are living creatures and require direct sunlight to thrive and show their natural beauty. Place your tank in front of a South-facing window, under a skylight, or in a Solarium. This replicates outdoor conditions, which enhances photosynthesis and helps to clean the glass.
When selecting a tank, be sure to make sure it is at least as long in one direction as the desired fish. For example, with a 10" goldfish, a tank measuring 8" x 8" would not be large enough (unless it is at least 10" tall). Fish need very little room to swim, as they will look just as pretty when stationary. Much like the effect of windows and mirrors on interior decorating, the clear glass tank walls give the fish the illusion of complete freedom and keep them content. Even if a fish discovers that it is confined, it will inevitably forget its problems after three seconds.
You should be sure to add your fish to your tank as soon as possible after purchase so as to keep long-term shock to a minimum. You will know when you have reached the desired stocking level if the cover to your tank is frequently knocked loose. When this happens you should find a heavier cover. When satisfied that the tank is full stocked, you may add tap water up to the brim.
For a designer effect, be sure the try the latest European craze with beer aquariums! These premium kits are somewhat costly to set up initially, but have natural antibacterial properties to keep your fish healthy. The attractive gold and amber colors will emphasize the beauty of your fish, and the inebriating effects allow for the most interesting and entertaining stunt-swimming patterns that (until recently) couldn't be seen outside of Mexico.
