First of all, you'll want to get a real history of fish keeping, so that you will know the best ways to tend to the species of fish you are interested in caring for. Fish keeping is believed to have begun thousands of years ago in Asian countries such as Japan and China, as well as several sections of Europe. Pools of carp were kept in ponds of the wealthy in Europe, mainly to be used as a meat substitute during religious holidays when meat was not allowed.
Asian fish keeping focused more on keeping the fish as pets than food. The tropical fish hobbyist was able to raise domesticated forms of the koi and goldfish in Asia, and you can still see varieties of these fish in man-made fountains and ponds at Chinese restaurants in your area. These tropical fish are especially enjoyable to look at, since they are usually very bright in color and have a peaceful temperament.
If you think you may want to be a tropical fish hobbyist for a living, you should also know how this hobby will work for you once you turn it into a business. Fish keeping is a booming business all over the world, and is a multi-billion dollar industry. The United States is actually the largest world market for this industry, since there have been almost 10 fish per household across the country in recent years.
As a tropical fish hobbyist, you should also know the technical sides of caring for the fish you’ve chosen. For instance, maintaining a clean and safe aquarium for your fish is important.
The water must be kept at a certain temperature for tropical fish--which is usually very cold--and other factors must be taken into consideration when setting up the tank, such as the water conditions.
The water must be virtually bacteria free, and some tropical fish will need water with more sodium, or sand at the bottom of the tank in order to simulate the ocean. If you want to find out how you can be a tropical fish hobbyist in your area, you can always ask your local pet store for details on fish breeders and hobbyists in your area.
