Introduction-

Goldfish are one of the best known of all freshwater fish. Chances are as a child each one of us kept a goldfish in a bowl. Well, goldfish are much more than just another pretty fish. Goldfish live wild in the waters of Asia (mostly China) where they are known as the Gibel Carp. They inhabit rivers, streams, ponds, lakes and ditches in China. They are known as a very hearty fish because of their ability to live in different types of water conditions, from almost freezing cold to warm water, and from fast running to stagnant water. Goldfish also known to be the first ever domesticated pet fish. The domesticated type has been around for over 1700 years. It all began in the Chang Dinesty when the classic gold colouration of the goldfish was created. This was done by a form of genetic mutation. As new varieties were created there began to be more world interest in goldfish. They were first brought to europe in the late 17th century where they could only be kept by the most. The breeding of goldfish then began to occur in europe. In 1874, goldfish finally reached north america.

Debunking the Myth: Can Goldfish Live in bowls?

It has always been thought that goldfish can live in bowls. Well they can live in bowls it does not mean that they should. Goldfish produce a large amount of waste which we all know is a source of ammonia. Ammonia being an ittitant to the fish. Ammonia turns into nitrite which is a poison to the fish. Large tanks with good filtration systems keep ammonia and nitrite in check, while in a bowl, they goldfish is left to suffer. Also, common and commet goldfish get very large, up to 2’ long. A small bowl is not a suitable home for a fish which grows so large. Keeping such a fish in small quarters will cause growth defects of the fish.


Varieties- (PICTURES COMING SOON)

There are endless varieties and colour variations of goldfish. Just some of the varities are:

Common- These are the more classic looking goldfish. When young, they are commonly marketed as feeder goldfish. This variety is gold to orange in colouration. Sometimes seen in black or white colouration.

Keeping Goldfish In the Home Aquarium and Pond

Goldfish do great in both ponds and aqariums. There are plusses and minuses to both. One of my favorite things about seing goldfish in a tank is getting to see the whole fish, rather than just the top of a fish like when kept in a pond. For the larger goldfish varieties, it is not very practical to keep them in an aquarium, so for Shubnkins, commons, and comets, i would say they are best kept in ponds enless you have a large enough system to keep them indoors. Most fantail varieties of goldfish stay under 8" and are perfectly suited for aquariums, but still do great in ponds. For one or two goldfish with a fantail a 20 gallon tank with good filtration is suitable. No heater is needed for a goldfish tank, although i would personally recommend one to hold a constant temperature (set it to about 72F). For each additional goldfish with a fantail, add another ten gallons. Therefore, two or three goldfish will be fine in a 30 gallon, or three or four in a forty gallon. This is the safest way to do things to avoid overstocking.

Keeping goldfish in a pond is an awsome way to enjoy them aswell while providing a very decorative flare to any backyard. Goldfish are also more likely to breed in ponds, which brings us to:

Breeding Goldfish

In my experience, goldfish breed more when their pond is neglected. It is said goldfish will only breed in outdoor ponds if they are kept outside for the winter. Well, my goldfish have spawned numerous times even though i have brought them inside my house every winter. They seem to like mud on the bottom of the pond, and lots of algea. Many plants in the water helps aswell. The fish will spawn on the roots of the plants. Make sure you have a male and female of the same species and they will pretty much do the rest. Goldfish must be over three years old to be sexually mature. My goldfish only ever spawn if my water is green with algea. Over 1000 eggs will be laid, and hatch hatch within 2-3 days. Feed the fry baby brine shrimp and eggyolk, aswell as other micro foods. Temperature also has a big part to do with the spawning of goldfish. Water must be warm in the day 65-75F and cold at night 48-58F.

Diet

Like most fish a varied diet is best. A mix of meaty foods a and vegitables are good. Feed peas, broccili, spirulina, bloodworm, brine shrimo, mosquito larvea, flake food, or pellet food regularely. Do not overfeed as Goldfish are very suceptable to bloat and swim bladder disorder, which brings us to:

Common Diseases of Goldfish
