Ryukin Goldfish

Ryukin Goldfish

The Ryukin Goldfish is a type of a goldfish that is egg-shaped. It has a short body which is stubby. They grow to a length of about 6 inches (15cm) although lengths of up to 10 inches (25 cm) have been reported in some cases. They can live for 20 years or more when well maintained, although most live for 10-15 years on average. There are two types of Ryukin Goldfish, namely:-

• Calico Ryukin Goldfish
• Tri-color Ryukin Goldfish

The Ryukin is a Japanese version of the Fantail Goldfish. Both of these goldfish will generally reach about 6 inches (15 cm), though some hobbyists report their Ryukins reaching up to a whopping 10″ (25 cm). The average goldfish lifespan is 10 – 15 years, though living 20 years or more is not uncommon in well-maintained goldfish aquariums and ponds.
Ryukin Goldfish are one of the hardiest species. This means that they are not prone to effect of water changes and the other tank conditions like temperature. For this reason, even a beginner can comfortably keep them without any fatalities. Apart from that, they can do well with the other species as long as they are not competitive. Also, they can survive in most environment such as a pond as long as safety is assured.

Ryukin Goldfish Diet

Ryukin Goldfish are omnivorous and hence they will feed on most kinds of food whether fresh, frozen or even flake foods. Ensure that you however strike a balance on the foods. Frozen food is recommended as opposed to live foods as this ensures that parasites are frozen to death before the food is fed to the Ryukin Goldfish. Ensure you also feed them with well despite the type of food even though they are not too demanding on the number of times in a day.

Fish tank

Ryukin Goldfish are hardy and easy to keep in a well-maintained tank. Minimum tank size is 10 gallons, so make sure water changes are frequent in such a small tank. Regular weekly water changes of 1/4 to 1/3 are strongly recommended to keep these fish healthy. Snails can be added as they reduce the algae in the tank, helping to keep it clean.
Ryukin Goldfish Diseases

If the fish tank is well maintained any disease that can affect the Ryukin Goldfish can easily be contained. However, in a scenario where any illness occur, it should be treated in a timely manner. Moreso, Ryukin Goldfish are hardy and most times they don’t end up dying if they are treated after an illness as long it is done in a timely manner. Another critical thing is that you should ensure sick fish should always be isolated for treatment and care. The quarantine tank should have no gravel or plants.

They include flukes, which are flatworms that infest the gills or body of the fish, fish lice (Argulus) that attach themselves to the body of the goldfish and anchor worms that resemble threads protruding from the fish.

3. Dropsy. This is a bacterial infection in the kidneys that can be fatal if not treated quickly. Other common bacterial infections include Fish Tuberculosis whose symptom is an emaciated (having a hollow belly) fish, Tail/Fin Rot and so on.
