Species Summary

If you’re thinking about adding a yoyo loach to your aquarium, it’s important to know as much as you can about this species. Here’s everything you need to know:


Yoyo loaches are native to Southeast Asia, specifically the rivers and streams of India, Indonesia, and Malaysia. They are a popular choice for aquarium enthusiasts due to their unique appearance and playful behavior.


On average, yoyo loaches can live for up to 10 years when cared for properly. However, their lifespan can be shortened if they are not provided with a suitable environment or proper nutrition.


Yoyo loaches have a distinct appearance with their black and yellow striped bodies. They also have a pair of barbels on their mouths that they use to search for food. When they feel threatened or stressed, their colors can become more muted.


Yoyo loaches can grow up to 6 inches in length, making them a medium-sized fish. However, they can also vary in size depending on their environment and diet.

Growth rate

The growth rate of yoyo loaches can vary depending on their environment and diet. However, they typically grow at a moderate pace and reach their full size within a few years.

Behavior & Temperament

Yoyo loaches are known for their playful and active behavior. They are also social creatures and thrive in groups of 3 or more. However, they can be territorial and may become aggressive towards other fish if they feel threatened or stressed.

Personally, I’ve found that yoyo loaches are a joy to watch in my aquarium. They love to play hide-and-seek and will often swim through the caves and tunnels in my tank.

However, I’ve also noticed that they can become aggressive towards other fish if they feel threatened. It’s important to provide them with plenty of hiding spots and a suitable environment to prevent any aggression.

Habitat and Tank Requirements

Tank Size

Yoyo loaches are active fish that need plenty of space to swim around. A 30-gallon tank is the minimum size recommended for a group of yoyo loaches.

However, if you plan on keeping more than 3-4 yoyo loaches, a larger tank is recommended. I personally keep my yoyo loaches in a 55-gallon tank and they seem to be thriving.


Yoyo loaches do not have any specific lighting requirements. However, it is important to provide a regular light cycle to maintain a healthy environment for your fish.

I recommend using a timer to ensure that your aquarium light is on for 8-10 hours per day.


Good filtration is essential for keeping yoyo loaches healthy. They produce a lot of waste, so you will need a filter that can handle the bioload.

I recommend using a canister filter or a hang-on-back filter. Make sure to clean your filter regularly to prevent any build-up of debris.


Yoyo loaches need a well-oxygenated environment to thrive. Aeration can be achieved through the use of an air stone or a powerhead.

I personally use a sponge filter in combination with a powerhead to provide both filtration and aeration.


Yoyo loaches are tropical fish and require a water temperature between 75-82°F. A reliable heater is essential to maintain a stable water temperature.

I recommend using a heater with a thermostat to ensure that the water temperature remains constant.


Yoyo loaches are bottom-dwelling fish that like to dig and burrow. A sandy substrate is ideal for these fish as it allows them to sift through the sand and search for food.

I recommend using a fine sand substrate with a depth of at least 2-3 inches.


Yoyo loaches enjoy having hiding places in their tank. You can provide this by adding rocks, caves, and driftwood to your aquarium.

However, make sure that the decorations are smooth and do not have any sharp edges that could harm your fish.


Yoyo loaches do not eat plants, but they may uproot them while digging in the substrate.

If you want to keep live plants in your aquarium, I recommend using hardy plants such as Anubias or Java Fern. These plants are easy to care for and can withstand the digging of yoyo loaches.

Water Quality

Water temperature

Yoyo loaches are tropical fish and require a consistent water temperature between 75°F and 82°F. Any fluctuations beyond this range can cause stress, illness, and even death.

Invest in a good quality heater and thermometer to ensure the temperature is always within the desired range.

Water pH

The ideal pH range for yoyo loaches is between 6.5 and 7.5. A pH level that is too high or too low can cause stress and weaken the immune system of your fish.

Test your water regularly and adjust the pH level as needed with a pH adjuster solution.

Water Hardness

Yoyo loaches prefer moderately hard water with a range of 8-12 dGH. If the water is too soft, it can cause stress and even lead to stunted growth.

If the water is too hard, it can cause problems with their kidneys and other organs. Test your water regularly and adjust the hardness level as needed with a water conditioner.

Water Changes

Regular water changes are essential for maintaining good water quality for your yoyo loaches. Aim to change 25% of the water in your tank every two weeks.

This will help remove any excess waste, chemicals, and debris that can accumulate in the tank and cause harm to your fish.

When doing a water change, make sure the new water is at the same temperature and pH level as the old water to avoid any shock to your fish.

Personally, I have found that maintaining good water quality is key to keeping my yoyo loaches happy and healthy. I make sure to test my water regularly and adjust the pH and hardness levels as needed.

I also do regular water changes to keep the tank clean and free of harmful chemicals. By following these simple steps, I have been able to enjoy my yoyo loaches for many years.

Tank Maintenance

Maintaining the tank for your yoyo loach is crucial to ensure their health and happiness. Here are some tips to keep in mind:

Clean the Tank Regularly: I personally clean my yoyo loach tank once a week. This includes removing any uneaten food, debris, and waste from the bottom of the tank. I also do a partial water change of about 25% to 30% of the tank’s water. This helps to keep the water clean and free of harmful chemicals.

Check the Water Parameters: It is important to keep the water quality in check. You should check the pH, ammonia, nitrite, and nitrate levels regularly. I use a test kit to check these parameters every week. If the levels are not within the safe range, I take appropriate measures to correct them.

Inspect the Equipment: The equipment in the tank, such as the filter, heater, and air pump, should be checked regularly. I make sure that they are working properly and replace them if needed. A malfunctioning equipment can harm your yoyo loach.

Keep the Tank Decorations Clean: Tank decorations, such as rocks and plants, can accumulate algae and debris. I clean them once a month to keep them looking good and to prevent any potential harm to my yoyo loach.

By following these simple tips, you can keep your yoyo loach healthy and happy in their tank. Remember, a clean and well-maintained tank is essential for the well-being of your yoyo loach.



Yoyo loaches are omnivorous fish and have a varied diet in the wild. They eat insects, crustaceans, worms, and algae.

In captivity, it is essential to provide them with a balanced diet that mimics their natural diet. You can feed them a combination of flakes, pellets, frozen or live foods, and vegetables.

I have found that my yoyo loaches enjoy live food the most. They go crazy for bloodworms and brine shrimp.

I also give them a variety of vegetables like cucumber, zucchini, and spinach. It is crucial to provide them with a balanced diet to ensure their health and longevity.

Feeding Schedule

Yoyo loaches are active fish and require frequent feedings. I feed my yoyo loaches twice a day, once in the morning and once in the evening.

I give them small amounts of food each time, so they do not overeat. Overfeeding can lead to health problems like obesity and swim bladder disease.

It is important to monitor their feeding habits and adjust the amount of food accordingly. If you notice that they are not eating or are eating too much, adjust the amount of food you give them.

Yoyo loaches can be picky eaters, so it may take some trial and error to find the right food for them.

Overall, feeding yoyo loaches is not difficult, but it does require some attention to detail. By providing them with a balanced diet and monitoring their feeding habits, you can ensure that they remain healthy and happy.

Behavior and Temperament

Social Behavior

Yoyo loaches are social creatures that thrive in groups. They are playful and active fish that enjoy exploring their environment.

They are known for their curious nature and will often investigate anything new in their tank.

When kept in groups of 6 or more, yoyo loaches will establish a hierarchy within the group. This is normal behavior and should not be a cause for concern.

It’s important to provide plenty of hiding places and territory for each fish to establish their own space.

Compatibility with Other Fish

Yoyo loaches are generally peaceful fish that get along well with other non-aggressive species. They are not known to be fin nippers and are compatible with most community fish.

However, it’s important to avoid keeping yoyo loaches with very small fish, as they may see them as prey. Additionally, they should not be kept with aggressive or territorial fish, as this can lead to stress and conflict.

How Many Yoyo Loaches Should be Kept Together

Yoyo loaches are social fish and should be kept in groups of 6 or more. Keeping them in smaller groups can lead to stress and aggression.

It’s important to provide enough space for each fish to establish their own territory and avoid overcrowding.

Personally, I have kept a group of 8 yoyo loaches in a 55-gallon tank and they have thrived. They are active and playful fish that provide endless entertainment.

Health and Disease

Common Health Issues

Yoyo loaches are generally hardy fish, but they can still be susceptible to various health issues. One common problem is ich, which is a parasitic disease that causes white spots on the fish’s body.

Another issue is fin rot, which is caused by bacterial infection and can cause the fins to deteriorate.

I have personally experienced my yoyo loach suffering from swim bladder disease, which caused him to float upside down. This can be caused by overfeeding or poor water quality.

It is important to monitor your fish’s behavior and health regularly to catch any issues early on.

Prevention and Treatment

The best way to prevent health issues in yoyo loaches is to maintain a clean and healthy environment for them. This includes regular water changes, proper filtration, and a balanced diet.

It is also important to quarantine any new fish before adding them to the tank to prevent the spread of disease.

If you do notice any health issues in your yoyo loach, it is important to take action quickly. Treatments for ich and fin rot include medication and raising the water temperature.

For swim bladder disease, fasting the fish for a few days and then feeding a small amount of boiled peas can often help.

Remember to always follow the instructions on any medication and consult with a veterinarian or experienced fish keeper if necessary.

Signs of a Healthy Yoyo Loach

When it comes to keeping yoyo loaches, it is important to know the signs of a healthy fish. Here are a few things to look out for:

  • Bright and vibrant coloration
  • Active and energetic swimming behavior
  • Clear and bright eyes
  • Smooth and shiny skin with no signs of discoloration or lesions
  • Healthy appetite and regular feeding behavior
  • Clear and clean water in the tank

As an avid yoyo loach keeper, I have found that paying close attention to these signs has helped me maintain a healthy and happy shoal of loaches in my aquarium.

Whenever I notice any changes in their behavior or appearance, I take immediate action to address the issue.

One thing to keep in mind is that yoyo loaches are social creatures and thrive in groups. Keeping them in a shoal of at least 5-6 individuals can help reduce stress and promote a healthy environment.

Overall, by regularly monitoring the signs of a healthy yoyo loach, you can ensure that your fish are happy, thriving, and a joy to watch in your aquarium.

Signs of a Sick Yoyo Loach

As a yoyo loach owner, it is important to keep a close eye on your fish and be aware of any signs that they may be unwell. Here are some common signs of a sick yoyo loach:

  • Loss of appetite
  • Erratic swimming behavior
  • Clamped fins
  • Visible spots or discoloration
  • Gasping at the surface of the water
  • Scratching against objects in the tank

If you notice any of these symptoms, it is important to take action quickly to prevent the illness from spreading to other fish in your tank.

One of the most common causes of illness in yoyo loaches is poor water quality, so be sure to test your water regularly and perform regular water changes as needed.

When I first got my yoyo loaches, I noticed that one of them was swimming erratically and seemed to be struggling to stay upright.

After doing some research, I realized that this was a sign of swim bladder disease, which can be caused by overfeeding or poor water quality.

I immediately adjusted their feeding schedule and performed a water change, and within a few days, my loach was back to swimming normally.

Remember, the key to keeping your yoyo loaches healthy is to be observant and proactive. By taking action at the first sign of illness, you can help ensure that your fish live long, happy lives.


Breeding yoyo loaches can be a challenging but rewarding experience. Here are some tips on how to successfully breed your yoyo loaches.

Breeding Setup

To begin breeding yoyo loaches, you will need to set up a breeding tank. This should be a separate tank from the one your yoyo loaches are currently living in.

The breeding tank should be at least 20 gallons in size and have plenty of hiding places for the fish.

I personally found that using a bare-bottomed tank with a few pieces of PVC pipe worked well for my breeding setup. The PVC pipes provided ample hiding places for the yoyo loaches to lay their eggs.

Breeding Process

Once you have set up your breeding tank, it’s time to introduce your yoyo loaches. You will need to have both male and female yoyo loaches in the tank to successfully breed.

I found that feeding the yoyo loaches live or frozen brine shrimp and bloodworms helped to stimulate breeding behavior.

The male yoyo loaches will begin to chase the female yoyo loaches around the tank, and this is a sign that they are ready to breed.

The female yoyo loaches will lay their eggs on the walls of the PVC pipes or other hiding places in the tank.

It’s important to remove the adult yoyo loaches from the breeding tank once the eggs have been laid, as they will eat the eggs.


Once the eggs have been laid, it’s important to take good care of them. The eggs will hatch in about three to five days, depending on the water temperature.

I found that keeping the water temperature around 78°F helped to promote healthy egg development. Once the eggs have hatched, you will need to feed the fry small amounts of food several times a day.

Overall, breeding yoyo loaches can be a fun and exciting experience. With the right setup and care, you can successfully breed your yoyo loaches and watch the fry grow into healthy adult fish.
