Ranchu Goldfish Overview
One of the most interesting features in identifying these fish is their lack of a dorsal fin. Instead, they grow a wen which is a large head growth. This affects their ability to control their bodies while swimming, making them slower-moving and sometimes requiring them to rest throughout the day in order to recover energy.
Because of their anatomy, they are among the most tranquil but handicapped goldfish. Due to their large and stocky bodies, they are more likely to develop swim bladder disorder than other slim-bodied goldfish.
They are not common in pet shops and should be ordered from a reliable breeder who breeds healthy genetic lines. To thrive, they need at least one compatible tankmate. They will feel more secure and social in a well-stocked and decorated tank.
Due to Ranchu’s delicate nature and body, extra care should be taken. They can become stressed if kept in an unfiltered and understocked tank. To avoid any health problems, these fish require a well-planned diet.
What is the cost of Ranchu Goldfish?
Non-competing fish can be purchased for between 5 and 25 dollars. Prices will vary depending on the source, availability, size, age, and source. Due to the high shipping cost of delivering live animals, buying from a pet shop will usually be more affordable.
The Typical Behavior and Temperament
They are peaceful and social fish that are slow-moving. You may see them foraging on the substrate looking for leftover food. They may also be seen hovering in the water or sitting down at the bottom. They love to investigate and are curious. Their charming swimming behavior, which includes wiggling around in the tank and an apparent eagerness to explore, will be obvious.
Appearance and Varieties
They come in many colors, with each one being unique and colored with metallic scales. Their colors can change over time. They can be multi-colored but they are more likely to be bi-colored with red, white, and gold, as well as white and white.
You may notice a raspberry-shaped growth on their head. Sometimes, it can cover their eyes and contribute to their inability to move.
Ranchu Goldfish Care
Habitat, Tank Conditions, and Setup
- Aquarium/Tank Size: A Ranchu fully grown Ranchu requires a minimum tank of 10 gallons. Each tankmate should have 5 gallons. Remember that the size of your tank will vary depending on the size and number of goldfish you have.
- Water Temperature and pH. Goldfish can tolerate a wide range of water temperatures, but it is not ideal. For goldfish, the best temperatures are between 65 and 77 degrees Fahrenheit. They need a pH of 7.2 to 7.6.
- Substrate: You can use sand or a suitable-sized gravel to fill your tank. As Ranchu like to forage for food, it is important that the gravel is not too large. It is essential to provide a safe and stable substrate for enrichment. Long-term, bare-bottom tanks are not the best.
- Plants can add variety and ornament to your aquarium. They can help maintain good water quality and enrich a fish’s diet. Ranchus will eat soft edible plants. If you don’t want Ranchus to eat these plants, then choose thick-leaved plants which are difficult to eat.
- Lighting: An aquarium light can be a great option if your aquarium is located in an area that doesn’t get enough light. Ranchu Goldfish require a night and day cycle. Make sure that they have at least 8-12 hours of darkness before going to sleep.
- Filtration: A suitable-sized filter is essential to maintain the tank’s water. It should be able to filter at least a few gallons more than the tank’s current capacity. Also, it should conduct water changes in accordance with the bioload and other parameters.
Are Ranchu Goldfish Good Tank Mates?
Ranchus aren’t the best tankmates for most fish, even fast-moving goldfish. Ranchus have difficulty moving due to their compromised body. Their wen can grow on their eyes, causing problems with their vision. This can make them unable to find food quickly, which can lead to stress and malnutrition.
They are not good community fish. They should not be paired up with any other fish species or slim-bodied fish due to bullying, fin nibbling, or competition for resources within the tank. They are good friends and can co-exist with similar-sized, slow-moving goldfish. This allows them to share food without being in danger of getting fin nipped.
How to feed Ranchu Goldfish
To be in good health, Ranchus need a varied diet. Ranchus are susceptible to swim bladder disorder. Avoid floating food as it may absorb too much air at the surface.
To maintain a healthy digestive system, and good body function, you should feed your pet good quality flakes, sinking pellets, or gel food.
Many goldfish die from poor nutrition, improper diets, and/or excessive portion sizes. This can easily be prevented with proper education.
We recommend The Truth About Goldfish as a best-selling book. It covers everything you need to know about goldfish nutrition, tank care, and illnesses. You can find it on Amazon.
To avoid rotten food and fouling the water, make sure you remove all unfinished food. This will prevent ammonia spikes. You should not give Ranchu too many calories, but ensure that each Ranchu has enough food. Limit the amount of food they consume in a matter of seconds.
Keeping Your Ranchu Healthy
Good water conditions are key to keeping your Ranchu healthy and happy. You need to keep the tank cyclic and have a good filter, and good aeration. Only make partial water changes if absolutely necessary.
A healthy fish will thrive on a well-balanced, high-quality diet. To avoid stress, keep them away from noisy noises, tank jostling, and frequent rapid movements. Your Ranchu should be kept in a peaceful, happy environment with compatible tank mates. Stress-free Ranchu means a happy and healthy one. This is possible only if you take the right care.
Breeding
Ranchu are wild breeders when the weather is warm and they have the right mates. If they are well cared for, goldfish can be bred between 1 and 2 years of age.
Males will display breeding stars to show that they are ready to breed. You’ll also see males following females and displaying goldfish breeding behavior.
The males should not be constantly chasing and stressing out the females. It’s best to put a tank divider in place and separate the genders if this happens. To avoid stress from mating behavior, ensure your tank is equipped with enough visual barriers.
Is Ranchu Goldfish suitable for your aquarium?
A Ranchu is a good choice if you have a tank that is the right size and has a steady stocking rate. You will enjoy Ranchu Goldfish as long as you maintain a tank with the right size and stocking rate, have smooth decorations and provide a healthy diet.

Do ranchu goldfish eat other types of fish?
Goldfish prefer to forage for food, consuming mostly bite-sized morsels of anything edible. However, if they come across small fish (e.g., baby goldfish), they do not discriminate and will eat it if they can catch it.
Can you combine all goldfish?
It is recommended to keep at least two goldfish in an aquarium for companionship and activity. Depression and lethargy can occur in solitary fish. Because goldfish are generally not aggressive, they can be kept with most community fish as long as the other fish are larger than the goldfish’s mouth.
How big can ranchus grow?
Aquarium Dimensions Ranchus, like any other goldfish, can grow to be 6-12 inches long. Over the course of decades, they can grow up to 18 inches long and a few pounds in an outdoor pond.
Ranchu is always at the bottom, why is that?
High ammonia, nitrites, nitrates, and a low pH all contribute to your goldfish sitting at the bottom of your goldfish aquarium. Poor water conditions, even if only for a short time, can cause permanent damage or even death.
How can you tell if your goldfish is content?
When your fish are happy and healthy, they: Swimming actively throughout the tank is preferable to hanging out or laying at the bottom, floating near the top, or hiding behind plants and ornaments. Eat on a regular basis and swim to the surface quickly during feeding times.
How long can a ranchu goldfish survive without eating?
Goldfish can survive for 8 to 14 days without food. They scavenge their aquarium and feed on algae during this time. Goldfish can go indefinitely without feeding in ponds, depending on the size and availability of algae and insects.
What size tank do Ranchu goldfish require?
These are large fish, so a tank of at least 10 gallons is required for one Ranchu, though we recommend starting with a 20-gallon or 30-gallon tank if you have the space in your home. Allow an additional 10 gallons for each additional Ranchu or other fancy goldfish you add to your aquarium.
