Ranchu Goldfish is a species of domestic goldfish from Japan. It belongs to the crucian carp family and should not be confused with the ranchu, and Asian gazelle.
A breeder developed them for this specific purpose to produce goldfish that could adapt quickly to changing environments.
As such, they are bred for their high resistance and tolerance to a wide range of water conditions, including low oxygen levels. They are also adaptable to slightly different temperature, salt, and pH ranges.
Ranchu Goldfish are bred as a common carp (Cyprinus carpio) hybrid. The ranchu gene is inserted into the common carp genome (CYPRUS CARP), giving these unique fish characteristics.
While they still possess a coloration similar to that of normal goldfish, they have an elongated body and special fins.
Characteristics of Ranchu Goldfish
Here are the Best 10 Characteristics of Ranchu Goldfish
1.The fins of the Ranchu Goldfish are larger than those of a common goldfish. The ranchu has a very long dorsal fin, and it constitutes almost a third of the fish’s body length.
The caudal fin is slightly larger than normal, but it is not as large as the wakin goldfish. The tail is often elongated and thus can be longer or shorter depending on the specific ranchu goldfish’s genes.
2. Ranchu goldfish have an elongated body with a double tail. Their fins are also very different from other goldfish breeds.
They feature a single long and narrow wing-like caudal fin (the single long fin on the bottom of goldfish used for propulsion) instead of two fused shorter fins seen in other goldfish varieties. Unlike normal goldfish, they also have highly specialized fins, which have either three or two fins.
3. Although also known as ‘silvers’ or ‘silvery,’ Ranchu goldfish are not silver but rather a silvery-gold color. They are still considered a genetic mutation since this color is extremely rare in the common carp (Cyprinus carpio) goldfish family and is only found in a handful of ranches strains.
4. The Ranchu Goldfish are very calm and gentle. They are considered a “garden variety” and are less likely to jump out of their tank than other goldfish varieties.
5. They have an average lifespan of 8–10 yrs, which is slightly higher than that of other goldfish.
6. The ranchu is a domesticated version of the wakin goldfish. This was thought to be achieved in the early 20th century by cross-breeding two different types of goldfish species: common carp (Cyprinus carpio) and wakin (Carassius auratus).
7. The origin of ranchus is controversial, with one theory stating that they were not developed in Japan but rather from the Chinese Carassius auratus. This is based on the fact that ranches were first introduced in Japan in 1997.
8. These goldfish are not very resilient to varying water conditions. They will die if kept in a very oxygen-depleted environment, such as a tank with low oxygen levels.
However, they can tolerate slower-oxygen tanks because of their high tolerance to anaerobic conditions.
9. Ranchu goldfish can be bred by carefully selecting healthy fish and regular cross-breeding. For example, the offspring will be the common variety when a female ranchu and male common carp are crossed.
10. They do not like strong currents or fast water flow in their tanks, although they can tolerate it longer than many goldfish breeds.
The harshness of the water current tends to shorten their lifespan because of the stress it causes them.
They also dislike sudden changes in water temperature and prefer stable conditions rather than varying temperatures.
The appearance
Ranchu Goldfish is unique due to the characteristic shape of their tail and fins, but not as unique as the wakin variety.
The arrival in Japan of wakins in 1882 led to a desire to develop a domesticated version of the fish, which led to ranches.
Compared to other goldfish varieties, Ranchu Goldfish have brains that are 20 percent larger. They have a larger brain-to-body ratio than any other fish known, including humans.
These fish are bred in Japan as ornamental fishes, but they have gained popularity because of their intelligence and personality. It has been said that ranches allow their owners to converse with them.
Breeds
The ranchu has three types (strains). The first is the Beni-Suitai Ranchu which boasts a red belly and brassy fins. Another strain is the Shiro-Suitai Ranchu which combines deep red fins with a white belly.
The third and most common strain is the Kohaku-Suitai Ranchu which has the same white belly as the Shiro-Suitai and red fins.
While this fish looks very similar to the common goldfish, it can be distinguished by its deeper body shape, longer dorsal fin, and elongated caudal tail. The ranchu has almost double the height of the common goldfish, which their different colors and unique eyes can easily recognize. The colors of the Ranchu Goldfish are a brassy yellow-gold color with a red belly on males and females.
Since this fish’s appearance is so similar to the common goldfish, it is not difficult to train both breeds from an early age. The only difference between its appearance and that of other fish is its elongated body.
Food of Ranchu Goldfish
As with other goldfish, the ranchu goldfish are omnivores and thus eat various foods. They enjoy live and frozen foods, including worms, shrimp, bloodworms, and brine shrimp. They love eating flakes and pellets made from commercial fish food.
Tanks of Ranchu Goldfish
Ranchu goldfish do well in a relatively small tank with a capacity of around 20–30 gallons (76–114 L). The tank should be placed on a sturdy stand to prevent tipping over.
The water should have a pH of between 6.0 and 7.0, with hardness at around 5-20 ° dGH (how hard is the water).
In larger tanks, the fish prefer soft sand as a substrate, and in smaller tanks, they do not like clay sand or gravel.
The environment should be at room temperature, and the fish can tolerate temperatures ranging from about 68-75 °F (20-24 °C).
The environment should be well-lit but not too bright, and the fish should not be exposed to direct sunlight.
Habited of Ranchu Goldfish
The ranchu goldfish prefers aquariums with a freshwater environment. Since it can be kept in both salt and brackish water, it is often found in combination tanks with various other fishes. It does well when kept in groups, as this helps to keep the water as clean as possible.
Diet of Ranchu Goldfish
Ranchu goldfish are omnivores and thus eat a variety of foods. They enjoy live and frozen foods, including worms, shrimp, bloodworms, and brine shrimp. They love eating flakes and pellets made from commercial fish food.
Care of Ranchu Goldfish
The ranchu goldfish is an omnivore and enjoys snacking on various foods. They may also eat other small fish in the tank if they are not fed enough. The ranchu goldfish is considered stress-resistant and can live for about 8 years if properly cared for.
The behavior of Ranchu Goldfish
The ranchu goldfish is a peaceful fish and gets along well with other fish. However, if they are not given the proper care, they can be aggressive toward other goldfish.
The ranchu goldfish is known for its bizarre behavior in which they suck on gravel and eat their tank mates. For example, a young ranchu ate small fry given to him by his owner on one occasion.
He had to be separated into another tank because he kept eating everyone else up. The ranchu goldfish is also known to jump out of the tank.
These fish may enjoy having a tank mate with them, although that varies depending on their personality.
How much does it cost a Ranchu Fish?
The ranchu fish is mostly known for its price, ranging from $7-$80. The cost for the ranchu fish depends on their size, color, and where you buy them from. You can find them in hobby stores and online stores.
Where Get Ranchu Fish?
Ranchu can be bought in some online stores and some tank shops. You can also find them in any Pet shop. The Ranchu Fish is a very beautiful fish with an interesting and unusual appearance.
The Ranchu fish is a natural hybrid of the common goldfish and red-finned tilapia, created by cross-breeding these two species in Japan.
Conclusion
The Ranchu fish is a very beautiful fish with an interesting and unusual appearance. The rancu fish is an omnivore or a carnivore.
The picture of the rancu fish resembles a common goldfish, which may lend to its nickname: the ‘common goldfish with red fins.’
In other words, it’s not just that they look like a common goldfish, but they also act like one! The rancu goldfish is not unique in appearance but also personality.
