Fancy Goldfish

orange orandaScientific Name Carassius auratus

Natural Habitat Fancies are not found in the wild. They are the result of selective breeding of the Common Goldfish which in turn was bred from the Crucian Carp around 1,000 years ago

Size Around 6 inches in aquariums although they are reports of Fancies growing to 18 inches in length

Temperment Peaceful with each other, will eat small subtropical fish

Aquarium 60 litres at least but the more the better

Comments Where would we be today without the odd Goldfish or two? The Fancies relative, the common goldfish, were the first fish to be kept around 1,000 years ago in China. Unlike today they were a sign of wealth and royalty, especially yellow strains such as the popular yellow canary Goldfish. So much so that it was illegal in China for anyone other then the Emperor to own the Yellow Goldfish.

Fancy Goldfish are far removed from these fish kept in ancient China however. Years of selective breeding have given the hobby many different shaped and colored Fancies. There are many strains of Fancies available such as the popular Oranda (above,) the Ranchu, Lionhead and Fantail. Most strains of Fancy Goldfish are considered to be rather resilient and the perfect fish for beginners. This is however not the whole case as Fancies grow very large and produce a lot of waste and so require weekly partial water changes and a good filtration system. If this can be provided then they are a wonderful fish to own but it should also be added that some species are not as resilient as others such as the Pearlscale Goldfish. It should also be mentioned that although many Fancies are resilient, they will not stand the cold temperatures of the garden pond as Common Goldfish can. This is due to generations of these fish being bred indoors.

Swimbladder disorder is also common in Fancies but this is easily corrected. Because Fancies have been bred to have a round body, this extra body mass puts a strain on the Fancie’s swimbladder and can result in any air becoming trapped in the fishes swimbladder for a period of time. To counter this simply feed your Fancies one of the many special Fancy Goldfish sinking food and the problem should soon correct itself. Fancies should never be mixed with the Common Goldfish as this may create many problems. The Common Goldfish may think that the Fancy is pregnant and chase it relentlessly.

The Fancy will not be able to hide as it is a far slower swimmer then the Common Goldfish. Such situations will lead to stress which may lead to the Fancy developing a disease such as white spot. It should also be mentioned that as the Common Goldfish is far faster then the Fancy Goldfish, it may eat the majority of the food you put in the aquarium and not leave enough for the Fancies. All in all, the Fancy Goldfish is a great fish to own but should be taken seriously and given a suitable aquarium with filtration rather then a small Goldfish bowl. If you want to own these animals then treat them with the respect it deserves because if it wasn’t for these fish we may not have the aquarium hobby that we all enjoy so much today!

Common Goldfish

Common GoldfishScientific Name Carassius auratus

Natural Habitat The Goldfish was bred from Crucian Carp in China during the time of the Tang Dynasty

Size 13 inches is an average maximum size although Goldfish have been known to grow to lengths as long as 23 inches

Temperment Peaceful, will eat fish small enough to fit in their mouth

Aquarium 125 litres

Comments The Goldfish was the first fish to be kept as a pet. It was bred from the Crucian carp over a thousand years ago in China and even today remains one of the most popular species in the hobby. Popular belief that the Goldfish is a small species that will live happily in a bowl couldn’t be further from the truth. The Goldfish is a hardy fish yet like all species poor conditions will cause it stress and eventually death.

These large fish should be kept in aquariums that suit its large size. An aquarium holding 125 litres is the minimum for three Goldfish although the bigger the aquarium the better. As you probably know already temperature is not a concern when keeping Goldfish so a heater is not neccessary. Many people keep Goldfish in garden ponds and if you ask me this is the best place for them unless you can supply them with a very large aquarium. You should also include an air pump for Goldfish as a lack of oxygen in the water will also cause them stress. Lastly and perhaps most importantly is providing a good filter.

Goldfish produce far more waste then other species of fish so correct filteration is a must. Weekly water changes of 25% to 40% are also needed to remove any waste from the aquarium and keep the water in good quality. There are not many species which can be kept with Goldfish. If you have a very large aquarium then it is possible to keep them with Weather Loach. I would not recommend keeping Common Goldfish with Fancy Goldfish however. Common Goldfish are far faster then the Fancy Goldfish due to there more streamline shape. Common Goldfish will thus eat any food you put into the aquarium before the Fancy Goldfish have a chance. Common Goldfish will also occasionly mistake Fancy Goldfish for being pregnant and take the oppertunity to chase and bully them. Feeding the Common Goldfish isn’t a hard, most fish stores should have a selection of granule and flake food which are purpose produced for the nutritional feeds of Goldfish. Feed Goldfish a small amount of food once a day and remove any food which is not consumed in 4 minutes.
