The lionhead goldfish is quite common, but not always recognized. You may have asked yourself ‘What is lionhead goldfish’ after hearing about this kind of fancy goldfish online or otherwise. Indeed, the lionhead isn’t as common as some other goldfish types in the average pet store. Therefore you may wonder how they differ.

The easy answer is the lionhead goldfish is a fancy goldfish with a raspberry-shaped growth, or ‘wen’ on the top of its head, and an egg-shaped body. These two traits mean it is more sensitive than some other goldfish and is thus not for beginners. To go further, the lionhead originated in China, where the very first fancy goldfish with similarly shaped bodies were also developed.

Nobody knows when the first goldfish with the wen, or growth on the head, appeared. However, we do know that the lionhead eventually found its way to Japan, where it was then taken to America and popularised worldwide.

You may also have heard of the ranchu goldfish, which is a descendant of the lionhead but is not the same fish. Likewise, the lionchu is a cross between ranchu and lionhead goldfish. Read on to find out more about the mysterious lionhead.

Lionhead goldfish can come in a variety of colors from red to white, calico, black blue, and silver. Some of these don’t necessarily describe what the fish looks like.

On the flipside, your fish won’t do well with sharp objects. This is because they can damage their delicate bodies and the hooded growth on their head.

Likewise, because of their poor swimming ability, they need room to maneuver. Even though they enjoy some hiding spots in between plants, they need enough space to swim freely. Therefore, don’t add anything too narrow where they can get trapped.

Plants For A Lionhead Goldfish Tank

Lionhead goldfish can be prone to digging up plants. Yet plants really do help keep the water clear and clean for these sensitive fish. Plus, a well-planted aquarium looks great and can keep your fish happier by offering them places to hide and feel safe.

Protein can increase the vibrancy of your fish. However, feed it in moderation because it also encourages the growth of the wen. if this gets too big, it can obstruct the eyes of your fish or even the gills.

However, that doesn’t mean they don’t enjoy exploring their environment. It’s cruel to keep any fish in a bare tank and a lionhead goldfish is no exception.

You will notice these quirky and eye-catching fish swimming through every part of their tank. They often go from foraging on the substrate and amongst the roots of plants to swimming with each other and interacting.

Occasionally they need to take a break, which can mean floating near the top of the tank or sitting near the bottom. In the latter case, this can sometimes just mean your goldfish is asleep! However, unusual lethargy or change in their usual inquisitive behavior indicates that they may be sick.

1. Dropsy

Dropsy is a disease that affects the kidneys and thus your fish’s water retention. In fancy goldfish like the lionhead, it may not be immediately apparent due to their egg-shaped body. What is lionhead goldfish body shape when healthy? Your fish’s body should be egg shaped, but not swollen.

Furthermore, you can notice dropsy if your fish rolls from side to side in the water, or its scales are sticking out, giving it a shape like a pinecone. Dropsy can be serious and hard to cure, so it’s best to prevent it in the first place by maintaining clean water conditions.

2. Bacterial Infections

These can take a number of forms but one of the biggest to look out for in lionhead goldfish is an infection of the wen. This can happen if your fish injures it on something, or if your fish gets food stuck between the folds of the wen. If this is the case, you’ll have to see a specialist aquatic vet, as this is such a sensitive area of the fish.

3. Ich/White Spot Disease

Ich or white spot disease is pretty easy to identify as true to its name, it causes the appearance of lots of white spots all over your fish’s body. It is caused by a protozoan parasite.

It can be treated with over-the-counter medications but always remove the fish to a new aquarium first and change the water in the old one. It’s also best to test for ammonia and nitrates too as dirty water increases your fish’s susceptibility to parasites.

4. Black Spot Disease

Black spot is rarer than white spot disease but still possible and causes lots of small black spots to form on your fish. This can be one reason why your goldfish is turning black. It is caused by a parasitic fluke that lives part of its lifecycle in fish and part in snails. To clear it up, give your lionhead goldfish a saltwater bath in a separate tank to prevent the parasite from continuing its lifecycle.

5. Hole-In-head Disease

Hole-in-head disease is a serious parasitic infection that can look shocking due to the way that small circular holes appear in your fish’s head. Though it can more commonly affect oscar fish and other cichlids, as well as discus fish, it’s important to know about it to distinguish it from normal variations in your fish’s wen.

Hole-in-head is caused by a parasite called hexamita. To treat it you need medication to kill the parasite, as well as cleaning the water and potentially transferring your fish to a new tank, plus dietary supplements to help your fish heal.

6. Swim Bladder Disease

Swim bladder disease is caused by either a parasitic or bacterial infection which means your fish can no longer use its swim bladder to stay afloat. You may see your fish struggling to maintain position in the water, and ultimately this is a sign that the water is dirty.

Remove your fish to another tank and this can be treated with an over-the-counter medication, although it’s best to see a specialist aquatic vet if you are unsure of the cause of the infection.

7. Wen Overgrowth

Lastly, wen overgrowth is not a disease. It is simply the instance when the wen of your lionhead grows to cover its eyes or gills so it cannot see or breathe.

It’s very important therefore to do something about it quickly. However, this involves clipping the wen which many first-time owners are unable to do at home. Therefore, with this one, it’s best to get specialist advice.

Breeding Your Lionhead

You will also need to lower to water temperature to 54 F/12 C.

Breeding a lionhead goldfish should only be done if you’ve got a good amount of experience breeding other, less sensitive fancy goldfish such as the fantail. Therefore, this breakdown assumed you’re already familiar with the specifics of how goldfish mate.

  • Breeding The Lionhead Naturally

To breed your fish naturally, you’ll have to set up a separate tank and provide a breeding mop or spawning mat. Goldfish spray over a thousand eggs at any one time and these need something to stick to.

When your fish are ready to breed you will see that the female has a slightly rounded abdomen. This is where she is carrying the eggs, and the male has white tubercles on his gills.

You will also need to lower to water temperature to 54 F/12 C or so. Then, you can raise it again to between 60-74 F/15-23 C to instigate spawning. This mimics the natural water temperature increase in spring when the wild ancestors of these carp would have bred.

Now comes one of the most spectacular parts of the process! You will see your fish begin to chase each other around the tank. This happens with the male pursuing the female, until she drops the eggs. After this, the male will fertilize them.

  • Breeding By Hand

If you can’t induce your female to drop her eggs, or the male isn’t chasing the female but she is still carrying eggs, there are other options. Did you know you can actually massage your fish’s abdomen to encourage her to release them?

A word of warning! This isn’t suggested for first-time fish breeders because of the risk of hurting your lionhead in the process.

It’s best for experienced aquarists. However, if you have bred goldfish before and can tell the female is ready, this is an option. The process is similar for the lionhead like with any other hardier goldfish – just make sure you’re careful of their wen!

  • Breeding Healthy Lionhead Goldfish

Sometimes, these fish can suffer due to their egg-shaped body and the pressure this puts on their swim bladder or digestive system.

After breeding you may, unfortunately, have to cull some of your fish. Otherwise, the number is simply unsustainable. In this case, it’s best to choose fish to cull that are on the shorter side in terms of body shape. These are less likely to survive and thrive to adulthood anyway, due to how it affects their internal organs.
