Gourami fish are popular among aquarium enthusiasts due to their vibrant colors and unique personalities. However, many people wonder whether these fish can live alone or require other fish’s company to thrive.

The answer to this question is not straightforward, as it depends on several factors.

Firstly, it is important to consider the species of gourami fish in question. Some species, such as the Dwarf Gourami, are known to be more solitary and can live alone without issue.

On the other hand, other species, such as the Three-Spot Gourami, are more social and may become stressed or lonely if kept alone.

Additionally, the size of the aquarium and the amount of hiding places available can also impact whether a gourami fish can live alone.


Can Gourami Fish Live Alone?


While gouramis are social creatures, they can live alone as long as their basic needs are met. However, it’s important to note that some gourami species, such as the dwarf gourami, are more social than others and may prefer to be kept in groups.

When keeping a gourami fish alone, providing them with adequate space and a suitable environment is essential.

A tank of at least 20 gallons is recommended for a single gourami, with plenty of hiding places and plants for them to explore.

It’s also essential to maintain the water quality in the tank, as gouramis are sensitive to changes in water chemistry.

Regular water changes and monitoring ammonia, nitrite, and nitrate levels are essential for keeping gourami healthy and happy.

In summary, while gourami fish can live alone, it’s essential to consider their social needs and provide them with a suitable environment.

A single gourami can thrive in a home aquarium with proper care and attention.


Factors Affecting Gourami Fish Solitude

Tank Size


Gourami fish are known to be peaceful and relatively easy to care for, but they do require a certain amount of space to thrive.

One of the most important factors affecting whether or not gourami fish can live alone is the size of their tank.

Gourami fish are relatively small but require a lot of swimming space. Generally, a single gourami fish should have at least a 20-gallon tank.

You’ll need an even larger tank if you keep multiple gourami fish.

In addition to the size of the tank, it’s essential to consider the shape and layout of the aquarium. Gourami fish prefer tanks with plenty of hiding places, such as plants, rocks, and driftwood.

A well-planted tank can help reduce stress and aggression in gourami fish, making them more likely to thrive alone.


Species Type


Another essential factor to consider when determining whether or not gourami fish can live alone is their species type.

There are many different types of gourami fish; some are more solitary than others.

For example, dwarf gourami fish are known to be relatively solitary and can often be kept alone in a tank.

On the other hand, some types of gourami fish, such as the kissing gourami, are more social and may require the company of other fish to thrive.

It’s essential to research the species of gourami fish you plan on keeping to determine whether or not they can live alone.

In some cases, keeping multiple gourami fish together may be necessary to ensure their well-being.

Overall, the size of the tank and the species type are two important factors to consider when determining whether or not gourami fish can live alone.

By providing a suitable environment and understanding the needs of your fish, you can help ensure they live a happy and healthy life.


Benefits of Solitude for Gourami Fish


Gourami fish are known to be peaceful creatures that can coexist with other fish species. However, there are several benefits to keeping them alone in a tank.

  • Firstly, solitary Gourami fish are less likely to experience stress and aggression. Gourami fish may feel threatened when kept with other fish, leading to anxiety and aggressive behavior. This can result in the fish becoming territorial and attacking other fish in the tank.


  • Secondly, keeping Gourami fish alone allows them to establish their territory and swim freely without competition. This can improve health and well-being, as they are not constantly competing for food or territory.


  • Thirdly, solitary Gourami fish are easier to care for. They require less maintenance and attention than when kept with other fish. This is because they do not produce as much waste, and there is no need to monitor their interactions with other fish.


In conclusion, while Gourami fish can coexist with other fish species, there are several benefits to keeping them alone in a tank.

Solitude can lead to reduced stress and aggression, improved health and well-being, more accessible care, and the opportunity to observe unique behaviors and personalities.


Potential Risks of Living Alone


While gourami fish can technically live alone, there are potential risks associated with doing so. Here are a few things to consider:


Stress and Loneliness


Gourami fish are social creatures that thrive in groups. They may experience stress and loneliness when kept alone, leading to health problems.

For example, a lonely gourami may become lethargic, lose its appetite, and become more susceptible to disease.




While some gourami species are peaceful, others can be aggressive, especially alone.

Without other fish to interact with, solitary gourami may become territorial and aggressive towards other tank inhabitants, including shrimp, snails, and smaller fish.




Gourami fish are intelligent and curious creatures that need stimulation and enrichment to thrive. Without other fish interacting with and exploring their environment, solitary gourami may become bored and exhibit undesirable behaviors, such as fin nipping or glass surfing.


Increased Maintenance


When kept alone, a gourami tank may require more maintenance than a tank with a group of fish. This is because a solitary fish produces more waste relative to the amount of water in the tank, which can lead to poor water quality and health problems.

In conclusion, while gourami fish can technically live alone, it is not recommended due to the potential risks associated with doing so. Keeping gourami fish in groups is always best to ensure they are happy, healthy, and thriving.


Tips for Keeping a Solitary Gourami Fish

Proper Feeding


When keeping a solitary gourami fish, it is essential to ensure they receive a balanced and nutritious diet. This can be achieved through various foods, including pellets, flakes, frozen or live foods. It is recommended to provide a mix of these different types of foods to ensure that the fish receives various nutrients.

It is essential to avoid overfeeding the gourami fish as this can lead to health problems such as obesity and poor water quality.

A good rule of thumb is to feed the fish in small amounts two to three times a day, only providing what they can consume within a few minutes.


Maintaining Water Quality


Maintaining good water quality is essential when keeping any fish, especially a solitary gourami fish. It is recommended to perform regular water changes of 10-20% every week to keep the water clean and free of harmful toxins.

It is also essential to monitor the pH and temperature of the water, as gourami fish prefer a slightly acidic pH of 6.5-7.5 and a temperature range of 75-82°F. A good filtration system is also crucial to keep the water clean and healthy for the fish.

In summary, providing a balanced and nutritious diet, avoiding overfeeding, performing regular water changes, monitoring pH and temperature, and having a sound filtration system are all critical factors to consider when keeping a solitary gourami fish.
