We will discuss their big forehead; why this is so special, their origins and history, the type of oranda goldfish you can keep, and how to take care of them. We will also address typical health issues, the arrangement of the best tank set up and the reasons why Oranda goldfish has been so popular among aquarists. Afterwards you will be in a good position to make a decision on whether to buy a big forehead goldfish to your home aquarium or not.
The Earliest History of the Big Forehead Goldfish.
The Oranda goldfish was first known in the 15th to 16th century and it was thought that they had been selectively bred in China and refined in Japan. The most iconic thing about the Oranda is its wen, the fleshy lump that appears on its head and face. Most fans refer to it as a huge forehead or a bubble-like crown.
Interestingly, the oranda did not exist in the wild. It is an artificial breed that has been developed by centuries of meticulous breeding. The wen was an object of allure and status mostly in Asian cultures, where Orandas were commonly given as gifts to rulers and placed in museums as living art. They remain very popular in the world today not only in home aquariums or in the competitive fish shows.
The Unique “Big Forehead” (Wen).
The large fleshy growth that covers the head of the Oranda is the characteristic feature of the animal. This wen is usually formed at an age of approximately 3-4 months of age, and this keeps rising as the fish grows. When an Oranda grows up, the wen may envelop all the top of its head, occasionally even about the cheeks and plates of the gills.
Though this might appear strange to novices, the wen is not a bad thing provided it is well taken care of. It is actually one of the most desired characteristics of the fish. Nevertheless, when the growth is too large, it may impair vision or expose the fish to bacterial infections. That is the reason why aquarists should give special attention to the quality of water and the food to maintain the wen in a good health and shape.
Fun fact: There are also orandas that are sometimes referred to as the lionhead with a dorsal fin since even though they look like lionheads in terms of the shape of their wen, they still have their dorsal fin unlike lionheads.
Types of Oranda Goldfish
Oranda goldfish have been bred in a wide range of beautiful varieties each having different color scheme and development of the wen. The following are the most popular types:
1. Red Cap Oranda
The most famous form is the Red Cap Oranda which is a bright white body with a bright red wen, which makes it look capped.
2. Black Oranda
This is very deep black everywhere, including its wen, and makes a gorgeous and dramatic effect.
3. Blue Oranda
One of the rarer types is the Blue Oranda which has shades of silver-blue with a weak wen, and this is much sought after by the collector.
4. Calico Oranda
Calico Orandas with their multicoloured patterned speckles are playful and lively and they often blend into the patchy scheme of colour.
5. Chocolate Oranda

Personality and Behavior
Oranda goldfish are docile and quiet creatures despite their weird looks. They do well in community tanks together with other like tempered species but may not do well when put together with fast and aggressive fish that may out compete them.
Their motion in the water is very still and smooth and they frequently move slowly because of their rounded bodies and soft flowing wings. Orandas are also very social and thrive in small groups and go on to be very attached to the tank mates and even acknowledge their owners with time.
There is also one thing, which is: Since their wen and their tender fins, Orandas are no strong swimmers. This does not imply that you should keep them in tanks where the currents are high or incomprehensible decorations that will harm them.
Tank Preparation of the Big Forehead Goldfish.
Being an Oranda, it takes more than a bowl, he requires a large well-kept aquarium to flourish. The following are the major setup requirements:
- Tank Size: 20 or more, 30 or more, depending on how many Orandas you are keeping, an extra 10 gallons of water.
- Filtration: A powerful and mild filtration is essential to ensure the quality of water without forming severe currents.
- Substrate and Decoration: smooth gravel or sand is preferable, and ornaments and vegetation which will not hurt their wen or fins.
- Water Requirements: Orandas like 65 72 F (18 22 C) of temperature, 6.5 7.5 of pH and low ammonia/nitrate content.
- Lighting: They have moderate lighting, which facilitates the exhibition of their beautiful colors and leaves the fish not stressed.
To enhance and increase oxygenation, it can also be nice to add live plants, although make sure to select hardy plants that cannot be dislodged easily, such as Anubias or Java Fern.
Diet and Nutrition
Orandas should eat a healthy diet to develop a strong level of immunity and retain their wen. They are omnivores, i.e. consume plants as well as animal food.
Recommended diet includes:
- Goldfish pellets of high quality sinking.
- Blanched (peas, spinach, zucchini) vegetables.
- Treats that are filled with protein such as bloodworms or brine shrimp.
- Fruity snacks (bites of orange or apple) occasionally.
The food intake should be 2-3 times a day in a small portion. As Orandas are susceptible to digestive problems such as swim-bladder disorder, flakes are not used, instead sinking ones are used to minimize air intake.
The Health issues in Oranda goldfish.
Orandas are beautiful, but delicate too, in comparison with other goldfish. Their body and shape place them at a risk of some health complication:
- Wen Infections: Bacteria or fungi can infect the folds of their wen if water quality is poor.
- Vision Impairment: Overgrown wens may obstruct their eyes, making it hard for them to compete for food.
- Swim Bladder Problems: Their round bodies make them more prone to buoyancy issues.
- Parasitic Infections: Like all goldfish, Orandas can suffer from ich, flukes, or other parasites if not quarantined properly.
Regular water changes, a balanced diet, and prompt attention to early symptoms are the best ways to prevent health complications.
