Many fish owners may wonder if their gourami fish is pregnant or overweight. This is a common question for those who have female gourami fish, as they can develop a rounded belly that may appear to be a sign of pregnancy.

However, this is not always the case.

Determining whether a gourami fish is pregnant or fat can be challenging, but certain clues can help fish owners make an informed decision.

One of the most significant indicators is the size and shape of the fish’s belly.

Pregnant gourami fish will have a rounder belly that is more prominent than usual, while overweight fish will have a larger belly that may appear more elongated.

Additionally, pregnant gourami fish may exhibit other signs, such as a change in behavior or appetite, while overweight fish may not display any other symptoms.

To provide proper care and avoid potential health issues, fish owners must understand the differences between pregnant and overweight gourami fish.

In the following paragraphs, we will explore the signs of pregnancy and obesity in gourami fish, as well as the steps that can be taken to ensure their health and well-being.


Identifying a Pregnant Gourami Fish

Physical Changes


Gourami fish can exhibit several physical changes when they are pregnant. One of the most noticeable changes is the distended belly.

Pregnant gourami fish will have a rounder and larger belly than their non-pregnant counterparts. The belly may also appear to be swollen or bloated.

The gravid spot, a dark spot near the vent, may also be more prominent in pregnant fish.

Another physical change that can be observed in pregnant gourami fish is the appearance of a protruding vent. This is caused by the enlargement of the ovaries and the pressure they exert on the vent.

The vent may also appear reddish or pinkish.


Behavioral Changes


Pregnant gourami fish may also exhibit some behavioral changes. They may become more territorial and aggressive towards other fish in the tank.

This is because they are protecting their eggs and offspring. Pregnant gourami fish may also become more reclusive and spend more time hiding or resting in plants or other decorations in the tank.

It is important to note that some physical and behavioral changes can also be caused by other factors, such as overfeeding or illness.

Therefore, observing the fish and looking for multiple signs before concluding that a gourami fish is pregnant is essential.

In summary, identifying a pregnant gourami fish can be done by observing physical changes such as a distended belly and protruding vent and behavioral changes such as increased aggression and reclusiveness.

However, it is essential to consider other factors causing these changes before concluding that a gourami fish is pregnant.


Distinguishing Between Pregnant and Fat Gourami Fish

Comparing Physical Traits


When determining whether a gourami fish is pregnant or just overweight, it is essential to compare physical traits.

Pregnant gourami fish will have a more rounded abdomen, while overweight fish will have a larger overall body size. The abdomen of a pregnant gourami fish will also be firmer to the touch than that of an overweight fish.

Another physical trait to consider is the color of the abdomen. Pregnant gourami fish will have a darker, more pronounced color in their abdomen, while overweight fish may have a lighter, less pronounced color.


Observing Eating Habits


Observing the eating habits of a gourami fish can also help determine whether it is pregnant or simply overweight.

Pregnant fish may have a decreased appetite, while overweight fish may continue to eat normally. Pregnant gourami fish may also become more aggressive toward other fish regarding feeding time.

It is important to note that these physical traits and behaviors are not always definitive indicators of pregnancy or overweightness. It is recommended to consult a veterinarian or experienced fish keeper for a more accurate diagnosis.


Physical Trait Pregnant Gourami Fish Overweight Gourami Fish
Abdomen Shape Rounded Larger overall body size
Abdomen Firmness Firmer Softer
Abdomen Color Darker, more pronounced Lighter, less pronounced
Eating Habits Decreased appetite Normal appetite
Aggressiveness More aggressive towards other fish No change in aggressiveness

Addressing Overfeeding Issues

Preventing Overfeeding


Establishing a feeding schedule and sticking to it to prevent overfeeding is vital.

Gourami fish should be fed twice daily, with only the amount of food they can consume in 2-3 minutes. It is important to avoid feeding them more than they can eat, as uneaten food can lead to water quality issues.

Another way to prevent overfeeding is to avoid feeding fish treats or snacks. While it may be tempting to give them extra food, it is essential to remember that their health is the top priority.


Correcting Overfeeding


Correcting the issue as soon as possible is essential if a gourami fish has been overfed. Overfeeding can lead to health problems like bloating, constipation, and swim bladder disease.

One way to correct overfeeding is to reduce the food given during each feeding. It may take some time for the fish to adjust to the new feeding schedule, but it is essential to be patient and consistent.

Another way to correct overfeeding is to fast the fish for one day a week. This allows their digestive system to rest and can help prevent health issues caused by overfeeding.

In conclusion, preventing and correcting overfeeding is crucial to maintaining the health of gourami fish. Establishing a feeding schedule, avoiding treats, and reducing the amount of food given during each feeding can help prevent overfeeding.

Fasting the fish for one day a week can help correct overfeeding and prevent health issues.


Caring for a Pregnant Gourami Fish

Proper Diet


When a gourami fish is pregnant, providing it with a well-balanced diet is essential.

This will ensure that the fish receives all the necessary nutrients to maintain its health and the health of its offspring.

A pregnant gourami fish should be fed various foods such as live or frozen brine shrimp, bloodworms, and high-quality flake or pellet food.

Feeding the fish smaller meals throughout the day rather than one large meal is recommended to prevent overfeeding.


Appropriate Tank Conditions


Proper tank conditions are essential for the health and well-being of a pregnant gourami fish. The tank should be spacious enough to allow the fish to swim freely.

A minimum tank size of 20 gallons is recommended for a single gourami fish. The water temperature should be maintained between 75-82°F, and the pH level should be 6.0-8.0.

Keeping the water clean and free from harmful chemicals or toxins is essential. Regular 25-50% water changes should be done weekly to maintain water quality.

In conclusion, providing a pregnant gourami fish with a balanced diet and appropriate tank conditions is crucial for the fish’s and its offspring’s health.

Following these simple guidelines ensures that your gourami fish remains healthy and happy throughout its pregnancy.




In conclusion, determining whether a gourami fish is pregnant or just fat can be challenging. However, some critical differences between the two can help fish owners make informed decisions.

Firstly, pregnant gourami fish will have a swollen belly more pronounced towards the back of their body. This is because their eggs are developing and growing in this area. On the other hand, if a gourami fish is simply overweight, their belly will be more evenly distributed throughout their body.

Another factor to consider is the behavior of the fish. Pregnant gourami fish are more reclusive and may spend more time hiding in plants or decorations. They may also become more aggressive towards other fish in the tank. In contrast, overweight gourami fish will not exhibit these behaviors and generally act like their usual selves.

It is important to note that other factors can contribute to a gourami fish appearing overweight, such as overfeeding or lacking exercise. Therefore, it is essential to maintain a healthy diet and provide plenty of opportunities for exercise and play.

In summary, determining whether a gourami fish is pregnant or just fat requires careful observation of their physical appearance and behavior. By paying attention to these factors, fish owners can make informed decisions about how to care for their fish and ensure their long-term health and happiness.
