The Lionhead Goldfish develops a fleshy growth that looks somewhat like a lion's mane... hence the name "Lionhead"!

The Lionhead Goldfish is by far the most popular and well known of the dorsal less goldfish. Rather than having the long slender body of the Common Goldfish or the Shubunkins, the Lionhead Goldfish is one of the more rounded or egg-shaped fancy gold fish.

Lionhead Goldfish have a double caudal (tail) fin and a double anal fin. This goldfish variety is very similar to the Ranchu Goldfish, a variant that was highly developed Japan.The Lionhead can be distinguished by a less curved contour shape to its back. Also, its caudal fin is quite similar to that of the Fantail Goldfish, while the Ranchu has a tail fin that splays out to the sides, often being almost horizontal.

This goldfish was bred in China to develop a "hood" that depicts the image of the mythical Chinese lion-dog. The distinctive raspberry or lion's mane appearance of the Chinese Lionhead Goldfish have led to its common name 'Lionhead' Goldfish. The amount of head growth differs for each fish. For some the broad head, except for its eyes, mouth and nostrils, can become completely covered with fleshy growth (sometimes impeding their vision) while others will develop hardly any head growth at all.

Lionhead Goldfish, Carassius auratus

These goldfish are available in a variety of colors. The solid metallic types include red, orange, chocolate, blue, and black. The nacreous types can be calico, bi-colored combinations of red and white or red and black, or tri-colored combinations in red, white, and black. There is also a red-capped variety with a bright red head and white body. Though pretty rare, there is also a long finned variety.

The Lionhead Goldfish is considered a rather delicate fish and is not recommended for beginners. Its swimming ability is cumbersome because of its rounded body which is further diminished by the lack of a stabilizing dorsal fin, a trait that is also seen in the Water-Bubble Eye Goldfish and the Celestial Eye Goldfish. Many of the elongated goldfish varieties like the Common Goldfish, Comet Goldfish, the Shubunkin, are not really good companions for the Lionhead Goldfish because they are fast swimmers and too competitive during feeding time. Better tank mates would be the similarly handicapped but less hardy Water-Bubble Eye Goldfish, Telescope Goldfish, and Celestial Goldfish. It won't win any races, but if kept with other slow-moving varieties the Lionhead Goldfish should get plenty to eat and do well.

Habitat: Distribution / Background

The goldfish of today are descendants of a wild carp fish, known as the Prussian Carp, Silver Prussian carp, or Gibel Carp Carassius gibelio (syn: Carassius auratus gibelio) which was described by Bloch in 1782. For many years it was believed that goldfish had originated from the Crucian Carp or Golden Carp Carassius auratus auratus described by Linnaeus in 1758, but more recent research is pointing toward the former.

These wild carp originated in Asia; Central Asia (siberia). They inhabit the slow moving and stagnant waters of rivers, lakes, ponds, and ditches feeding on plants, detritus, small crustaceans, and insects. In the early 1500's these fish were exported first to Japan and then to Europe and were developed into the wonderful colors and forms of gold fish we see today.

The Lionhead Goldfish, or Chinese Lionhead Goldfish, is one of the older varieties of fancy goldfish. In China this fish was bred to develop a "hood" that depicts the image of the mythical Chinese lion-dog. Its ancestor and precursor is the Eggfish, known as Maruko in Japan. The Lionhead and all other dorsal less fish resulted from developments of this egg shaped fish. The Eggfish itself is not popular in the United States. Although it can be found in the orient, it is very rare in the US and would be expensive. Today there are more than 125 captive bred fancy varieties.

  • Scientific Name: Carassius auratus auratus
  • Social Grouping: Groups
  • IUCN Red List: NE - Not Evaluated or not listed - There are no wild populations of this captive bred variety.


The Lionhead Goldfish is an egg-shaped variety of goldfish. The body is short and stubby and they have a double caudal (tail) fin and a double anal fin. Their most distinctive feature is the head, which except for its eyes, mouth and nostrils, can become completely covered with fleshy growth. These fish mostly have short fins, but there is a long-finned variety that is rather rare.

  • Goldfish colors
    Available color varieties include the solid metallic types in red, orange, chocolate, blue, and black; nacreous types can be calico, bi-colored combinations of red and white or red and black, or tri-colored combinations in red, white, and black. There is also a red-capped variety with a bright red head and white body.
  • Size - Weight
    Lionhead Goldfish will generally reach about 5 inches (13 cm), though some hobbyist report their Lionhead's reaching more than a whopping 10" (25 cm).
  • Goldfish lifespan
    The average goldfish lifespan is 10 – 15 years, though living 20 years or more is not uncommon in well maintained goldfish aquariums and ponds.
  • Size of fish - inches: 10.0 inches (25.40 cm) - This fish will only reach ten inches in the best of conditions, the Lionhead Fancy Goldfish usually reaches around five inches.
  • Lifespan: 15 years

Fish Keeping Difficulty

Lionhead Goldfish are some of the more delicate species of goldfish. Unlike the flat-bodied types of goldfish, they have a lower tolerance for pollution. They will need good care and plenty of space. When it comes to feeding, they will not thrive well with fast competitive tank mates.

Many people will keep goldfish in small one or two gallon goldfish bowls with no heater or filtration. But for the best success in keeping goldfish, provide them the same filtration, especially biological filtration, that other aquarium residents enjoy.

  • Aquarium Hardiness: Moderately Difficult - The Lionhead Fancy Goldfish is compartively very weak relative to other Fancy Goldfish. The Wen is prone to infection, if the aquarist notices any rawness or irritation it is wise to treat right away.
  • Aquarist Experience Level: Intermediate

Foods and Feeding

Since they are omnivorous, the Lionhead Goldfish will generally eat all kinds of fresh, frozen, and flake foods. To keep a good balance give them a high quality flake food everyday. To care for your Lionhead Goldfish, feed brine shrimp (either live or frozen), blood worms, Daphnia, or tubifex worms as a treat. It is usually better to feed freeze-dried foods as opposed to live foods to avoid parasites and bacterial infections that could be present in live foods. Due to their fleshy head growth they can have poor vision and a harder time seeing their food, so need extra time to feed.

  • Diet Type: Omnivore
  • Flake Food: Yes
  • Tablet Pellet: Yes
  • Live foods (fishes, shrimps, worms): Some of Diet
  • Vegetable Food: Some of Diet
  • Meaty Food: Some of Diet
  • Feeding Frequency: Several feedings per day

Aquarium Care

Regular weekly water changes of 1/4 to 1/3 is strongly recommended to keep these fish healthy. Snails can be added as they reduce the algae in the tank, helping to keep it clean.

  • Water Changes: Weekly

Aquarium Setup

Setting up an aquarium in a manner that will keep your fish happy and healthy is the first step to successfully fish keeping. Here are aquarium parameters to consider in choosing goldfish aquariums, filtration, lighting, and decor as well as temperature and water movement.

  • Minimum Tank Size / Length:
    The shape and size of the goldfish aquarium is important and depends upon the number of fish you are going to keep. Goldfish need a lot of oxygen and produce a lot of waste. Keep the tank size and shape in mind when you are buying your fish.
    • Tank Shape
      A large surface area of water will help minimize goldfish suffering from an oxygen shortage. Surface area is determined by the shape of the tank. For the same volume of water, an elongated tank offers more surface area (and oxygen) than a tall tank. In a goldfish bowl, filling the bowl to the middle offers more surface area than filling the bowl to the top. Always provide the maximum amount of surface area.
    • Tank size
      It's best to start with a 20 - 30 gallon tank for your first goldfish and then increase the size of the tank by 10 gallons for each additional goldfish. Providing a large amount of water per fish will help dilute the amount of waste and reduce the number of water changes needed
    • Formula: # of fish per gallon of water
      A general rule of thumb, but only for young fish, is 1 inch of fish (2.54 cm) per 1 gallon of water. This rule applies only to young fish and is not adequate as they grow. Larger gold fish consume much more oxygen than young fish so maintaining this formula for growing fish will stunt them, and can contribute to disease and even death.
    • Fish: size and growth
      To allow for growth, either buy fewer fish than the maximum number of fish (based on the formula above) or be prepared to get a larger tank. Larger gold fish consume much more oxygen than young fish so maintaining this formula for growing fish will stunt them, and can contribute to disease and even death
  • Aquarium Lighting
    Most aquariums come with a cover that includes lighting. A cover for the tank is desirable as it reduces evaporation and though they are not prone to jumping, on occasion some gold fish will jump out. Lighting is not essential for goldfish, but does make the aquarium a nice show piece and lighting will help if you have live plants.
  • Filtration
    Goldfish produce a lot of waste. Good filtration, especially biological filtration, is very helpful in maintaining the water quality of the aquarium. Filtration systems remove much of the detritus, excess foods and waste. This helps keep the tank clean and maintain the general health of the goldfish.
  • Substrate
    Provide a gravel substrate to help create a natural and comfortable environment for your fish. A medium sized gravel works best..
  • Aquarium Decor
    You can add some decor, but make sure that all ornamentation is smooth with no protruding points or sharp edges. Smooth rocks or driftwood, should be used sparingly if at all.
    Aquarium plants would be the best choice of aquarium decor for goldfish, but unfortunately these fish are diggers. Consequently live plants may be uprooted. Artificial plants make a good substitute and silk plants are safer than plastic ones.
  • Temperature: Goldfish are a cold water fish and will do best at temperatures between 65 - 72° F (18°- 22° C). Unlike the flat-bodied types of goldfish, the Lionhead has a lower tolerance for pollution and cannot tolerate temperatures much below 60° F (16° C).
  • Water Hardness: 5 - 19° dGH
  • ph: 6.0 to 8.0
  • Water Movement: Moderate.
  • Water Region: These fish will swim in all areas of the aquarium.
  • Minimum Tank Size: 10 gal (38 L) - Ten gallons is the absolute minimum required to house this type of fancy goldfish. It has high oxygen requirements, produces a lot of waste, and will have very stunted growth if it is kept in a smaller aquarium or bowl.
  • Suitable for Nano Tank: Sometimes
  • Substrate Type: Any
  • Lighting Needs: Moderate - normal lighting
  • Temperature: 65.0 to 72.0° F (18.3 to 22.2° C)
  • Range ph: 6.0-8.0
  • Hardness Range: 5 - 19 dGH
  • Brackish: Sometimes - Goldfish are freshwater fish, but they have some tolerance for slightly brackish water. Yet any salinity for C. auratus must be kept below 10%, a specific gravity of less than 1.002.
  • Water Movement: Moderate
  • Water Region: All

Social Behaviors

Goldfish are very social animals and thrive in a community. Not only are they a great community fish but they are great scavengers as well. It is really not necessary to add other scavengers or other bottom feeders to the aquarium when you have goldfish.

When choosing tank mates, keep in mind the physical traits of the Lionhead Goldfish. Like the Telescope Goldfish and the Celestial Goldfish, the Lionhead can be visually handicapped. Further its swimming ability is cumbersome because of its rounded body and the lack of a stabilizing dorsal fin, a trait that is also seen in the Water-Bubble Eye Goldfish. While the Lionhead cannot readily compete for food with fast swimming types of goldfish, these similarly handicapped varieties can make good companions.

  • Venomous: No
  • Temperament: Peaceful
  • Compatible with:
    • Same species - conspecifics: Yes
    • Peaceful fish (): Safe
    • Semi-Aggressive (): Threat
    • Shrimps, Crabs, Snails: Safe - not aggressive
    • Plants: Threat - Goldfish will eat many kinds of aquatic plants, and their constant search for food can end up uprooting plants that they don't eat.

Sex: Sexual differences

Although is it impossible to sex Goldfish when they are young and not in breeding season, the male is usually smaller and more slender that the female. In the breeding season the male has white prickles, called breeding tubercles, on its gill covers and head. Seen from above the female will have a fatter appearance as she is carrying eggs.

Breeding / Reproduction

Lionhead Goldfish are egg layers that spawn readily in the right conditions. See Breeding Freshwater Fish - Goldfish for more information on breeding Goldfish.

  • Ease of Breeding: Moderate

Fish Diseases

Goldfish are subject to the same diseases as tropical fish. A couple of the more common problems are Ich, Swim Bladder Disease, and external parasites including flukes, lice and anchor worms.

The Lionhead Goldfish is readily available in fish stores and on-line, and is inexpensive

Our lionhead was a very active tankmate with our fantails but recently has started to hide in the vegetation, she or he is breathing normal but not swimming. mostly stays in one spot. Do you think she could be pregnant? She seems to have become very rounded. Please comment.

  • Clarice Brough - 2014-02-16
    It's possible she could be pregnant.
  • Ineke - 2014-08-21
    Why doesn't any body see that these poor things are basically handicaspt, they are totally bred out of proportion.

I have gotten 2 lion head fish and 2 black moore. They are so cute and I love them a lot. When I bought them they were in the same tank so I figured it would be fine to keep them together. They are all very active and seem to enjoy each other. Their names are (lionheads) R2 and D2; (black moors) Yoda and O-bee. They make great entertainment for everyone who sees them!

I have two goldies, Gibson and Flash, that are housed with three Dojo loaches. I have seen no agressive activity, unless you are here at dinner time.. and all I can say is "piggy, piggy, piggy! I first bought the goldies when they were 2.5 inches they are now about 4 inches and look like they are going to keep growing. Being the considerate fishkeeper that I am I first made internet inquiries about housing, feeding and life expectency. I have the group in a 50 gallon with two filters, one canister (rated for 125 gallon) and a sponge filter (rated for 125 gallon). I have several plants with my goldies... Anubias, Vals, swords, momosa ball and Cryptocornye Wendetti. They love to munch on Duckweed! Which is good because I have an abundence in my other thanks. I do not recommend them for first time fishkeepers, they need really clean water and large tanks. Most people can't figure out why they can't keep them in a 10 gallon, they are high waste producers and will end up killing them selves with out the proper care. These fish are a great source of entertainment and attention! As long as you treat them well they will have healthy happy lives.

I personally love lionheads!! I have one now that I have had him (im assuming)for about 3 years. His name is Squeegy and he is extremely active. He has grown to about 5 inches long, and does not look like he is going to stop growing any time soon. I have noticed that he is quite fond of fresh peas, and is a pig when it comes to feeding time. I highly recommend this type of fish for anybody who loves goldfish. Lionheads are beautiful and they are funny to watch and raise.

  • Vadiraj - 2010-05-14
    I had beautiful lion head goldfish which died due to lack of oxygen. . . She was stunning to look and was always very active but today i forgot to check my aquarium before leaving to office and my air pump had stopped working. Some how male fish survived but my beautiful little jenny died:( i am feeling so sad for her. . . My bad:(

I have three lionheads, one black, one orange, one gold and black. Also a black moor and a calico. They are all adorable. I am concerned for my big orange, as her head scales are growing down over the top of her eyes and she will soon be almost blind. Can the scales be cut back without hurting her? Does anyone know if there is anything I can do for her? She's my favorite!

  • Clarice Brough - 2014-03-09
    I don't know if they can be 'cut back', that sounds a little intrusive to me. It may just be her genetic makeup. These fish are breed for a number of things, with a large cap being one of them. I hope she will be alright, but I don't know that you can physically alter this. Perhaps another reader can give you a better idea.
  • DeeDee - 2014-03-27
    I currently have two lionheads in a 28 gallon tank. They are both about 2 inches. I'd like to add one more but I am concerned about stunting them. They are so adorable, just like all the others say.
