Tosakin Goldfish Care Guide (Tank, Food, Water, Filter)

Tosakin Goldfish is one of the rarer species of goldfish. They are quite delicate and need extensive care, mainly because of their tail structure.

Read on to find out more about how to care for Tosakin Goldfish.

How Long Do Tosakin Goldfish Live?

The average lifespan for a Tosakin Goldfish is 10-12 years. However, they can live for more if they are well cared for.

There are many factors that can affect the lifespan of a Tosakin Goldfish, such as water quality, diet, and tank mates.

Tank Requirements for Tosakin Goldfish

Let’s have a look at the ideal tank conditions that will give your Tosakin Goldfish to live a long and healthy life.

Ideal Tank Size

The recommended tank size for each Tosakin Goldfish is 10 gallons.

However, you can still have 2 Tosakin Goldfish in a 10-gallon tank, provided there are no other fishes with them.

It is important to have a larger tank if you plan on keeping more than one Tosakin Goldfish because they are very active swimmers and need plenty of room to move around.

Filtration & Aeration

Since Tosakin Goldfish produce a lot of waste, it is important to have a good filtration system in their tank.

A canister filter or an external hang-on-back filter will work well. It is also important to have strong aeration in the tank, as Tosakin Goldfish are sensitive to low oxygen levels.

Experts recommend that your filtration system should filter the water four times every hour at the very least. For best usage, you should have both biological and mechanical media in your filter.

Substrate for Tosakin Goldfish

Tosakin Goldfish prefer a soft, sandy substrate in their tank.

Not only does it increase the water quality of your tank, but it also allows some beneficial bacteria to grow.

Plants & Décor for Tosakin Goldfish

You can put live plants in a Tosakin Goldfish tank. You can also use fake plants, driftwood, and rocks to decorate the tank.

Just make sure that there are no sharp edges that could injure the fish.

Floating plants like water lilies or water hyacinth can also be included in the water tank. They will also improve the water quality of your aquarium.

Lighting Conditions

Tosakin Goldfish prefer a dimly lit tank.

Bright lighting can cause stress and may even affect their coloration. You can use fluorescent, UV, or LED lighting.

What to Feed Tosakin Goldfish?

Tosakin Goldfish are omnivores; hence they can eat both plants and animals. Good quality goldfish pellets or flakes can be used as their base food source.

You can supplement their diet with live, frozen, or freeze-dried foods.

Some good options for feeding Tosakin Goldfish include:

  • Brine shrimp
  • Bloodworms,
  • Daphnia,
  • Tubifex worms
  • Kale

It is important to feed Tosakin Goldfish several small meals per day rather than one large meal. This helps to prevent them from becoming overfed and developing health problems.

Ideal Water Conditions for Tosakin Goldfish

Tosakin Goldfish prefer soft, slightly acidic water.

The ideal temperature range for Tosakin Goldfish is 68-74 degrees Fahrenheit. The pH levels of the fish tank should be between 6.0 and 7.8.

It is recommended to perform a 25% water change every two weeks for Tosakin Goldfish.

However, if your Tosakin Goldfish are kept in a well-maintained aquarium with high-quality filtration, you may only need to perform a water change once per month.

Do Tosakin Goldfish Require a Filtration System?

No, Tosakin Goldfish do not require a filtration system. However, it is still recommended to have a filter in the tank as it will help to keep the water clean and clear.

Aquarium filters come in a variety of types and sizes. The type of filter you choose will depend on the size of your aquarium and the number of fish you have.

For a small aquarium with a few Tosakin Goldfish, a hang-on-back filter or an internal filter would be sufficient.

For a larger aquarium, canister filters are the best option as they provide greater flow and filtration capacity. Canister filters are also less likely to become clogged, making them easier to maintain.

Common Diseases in Tosakin Goldfish

Now that we have looked at the ideal tank conditions and diet for Tosakin Goldfish, let’s also quickly learn about some of the common disease they can get.


Ich is a common disease that can affect Tosakin Goldfish. Ich is caused by a parasite that attacks the fish’s skin, resulting in white spots on the body.

Ich can be treated with medication, but it is important to remove any carbon from the filter before using medication, as this can make it less effective.

Columnaris is a bacterial infection that affects the gills, fins, and skin of Tosakin Goldfish. Columnaris can cause the fins to disintegrate and turn white or brown.

It can also lead to gill damage and difficulty breathing.

Columnaris is often fatal if left untreated. Treatment for Columnaris typically involves antibiotics or adding chemicals to the water.

Tail Curling

Tail curling is a condition that can be caused by a number of factors, including poor water quality, infection, or genetics.

Tail curling can be treated with medication, but it is important to identify and correct the underlying cause of the condition.

Swim Bladder Disease

Swim bladder disease is a condition that affects the swim bladder, which is a sac located in the fish’s abdomen that helps to control buoyancy.

Swim bladder disease can be caused by a variety of factors, including poor diet, infection, or genetics.

Symptoms of swim bladder disease include buoyancy problems and abnormal swimming patterns. This disease can be treated with medication and maintaining water quality.


Flukes are parasitic worms that can infect Tosakin Goldfish. Flukes attach themselves to the fish’s body and feed on their blood.

Flukes can cause various symptoms, including lethargy, appetite loss, and difficulty breathing.

Flukes are typically treated with medication, but it is important to remove any carbon from the filter before using a medication, as this can cause the medication to be less effective.

How to Prevent Tosakin Goldfish from Getting Sick

Tosakin Goldfish should be quarantined for two weeks before being introduced to a new tank.

A quarantine tank is a smaller tank that is used to house new fish until it is determined that they are healthy and free of diseases.

During the quarantine period, observe the Tosakin Goldfish closely for any signs of illness. If you notice any signs of illness, treat the fish immediately and consult a veterinarian if necessary.

It is also important to make sure that your Tosakin Goldfish are compatible with the other fish in your aquarium.

Some fish are known to be aggressive towards others, which can lead to fighting and stress. To avoid aggression, do not keep Tosakin Goldfish with larger fish or with fish that have similar coloring.

What Is the Typical Behavior of Tosakin Goldfish?

Tosakin Goldfish are peaceful fish that do well in community tanks. They are slow swimmers because of their rounded bodies.

You will often find them floating around the tank, unlike other fishes who prefer hiding in cracks or crevices.

What Type of Company Should Tosakin Goldfish Have?

Tosakin Goldfish are social fish that do well in groups. They should be kept with other peaceful fish that are similar in size.

Tosakin Goldfish are not recommended for community tanks with larger fish or aggressive fish.

It is also important to keep Tosakin Goldfish with fish that have similar coloring, as they may be bullied by fish with brighter colors.

Because of their tail structure, Tosakin Goldfish can not flee from their attackers that easily.

Differentiating Between Male and Female Tosakin Goldfish

Tosakin Goldfish are notoriously difficult to sex.

However, there are a few methods that can be used to determine the gender of your Tosakin Goldfish.

One method is to look at the shape of the fish. Male Tosakin Goldfish tend to have a more slender body shape, while female Tosakin Goldfish tend to be rounder.

Another method is to look at the fins. Male Tosakin Goldfish usually have longer and more pointed fins than females.

You can also check for the presence of eggs. Female Tosakin Goldfish will often have small white eggs visible on their underside, while males will not.

If you are still unsure about the gender of your Tosakin Goldfish, it is best to consult a veterinarian or an experienced fish keeper.

How to Breed Tosakin Goldfish

Breeding Tosakin Goldfish is a relatively easy process once you have correctly sexed them.

To breed Tosakin Goldfish, you will need to set up a breeding tank. The breeding tank should meet all the requirements of the tank that are ideal for Tosakin Goldfish.

Make sure the water quality and pH levels are optimum.

Their breeding usually takes place in warmer water, so you should increase the water temperature slightly.

It is also important to add plenty of plants and hiding places to the breeding tank, as the female Tosakin Goldfish will have a sort of anchor to lay her eggs on.

Once the breeding tank is set up, you will need to introduce a male and female Tosakin Goldfish. The male Tosakin Goldfish will chase the female around the tank until she is ready to lay her eggs.

Once the eggs are laid, the male Tosakin Goldfish will fertilize them.

The eggs will hatch within 10-14 days. The fry (baby fish) will be free-swimming within a few days and will be able to eat baby brine shrimp or powdered goldfish food.


Tosakin Goldfish are quite rare, which makes them a lot more valuable than other goldfish species. Because of their delicate nature, they require a lot of care.

Those who are new to fishkeeping should avoid having them as pets until they have gained more experience.
