Dwarf gourami fish do not get pregnant in the traditional sense, as they are egg-layers that reproduce through external fertilisation. However, female dwarf gouramis do become gravid, meaning they swell with eggs and can be bred under the right conditions.
To identify if a female dwarf gourami is gravid, look out for the following signs:
- A rounded, swollen belly, as if the fish has swallowed a marble
- Changes in colour patterns, such as becoming more pale
- Changes in behaviour, such as swimming close to the male with their bodies touching
- The presence of a bubble nest, which the male dwarf gourami will build after mating with the female

Dwarf gourami females don't get pregnant in the traditional sense, but they do become gravid with eggs
Unlike other fish, Dwarf gourami females don't get pregnant in the traditional sense. Instead, they become gravid with eggs, which means they swell with eggs that will be fertilized externally. This process is known as spawning, and it's important to distinguish it from pregnancy, as it involves different care requirements and considerations.
Identifying a gravid Dwarf gourami female can be tricky, as the physical signs are often subtle and can be mistaken for other conditions. However, there are some telltale signs to look out for. Firstly, you may notice a rounded belly, as the female's belly becomes more pronounced and boxy. Secondly, the female may exhibit changes in behaviour, becoming more reclusive or territorial as she prepares for the arrival of her fry. She may also show less interest in food. Finally, you may observe changes in colour patterns, such as more vibrant and intense colours or the development of dark spots on their bellies.
If you suspect your Dwarf gourami female is gravid, it's important to provide a safe and stress-free environment, a nutritious and varied diet, and properly monitor her health and behaviour. A suitable breeding partner and a proper tank setup are also crucial for successful and stress-free spawning.
- Swelling in the belly, particularly underneath the front of her belly, as if she has swallowed a marble.
- Expanded belly in one area, which is usually more towards the front.
- Stretched and slightly paler scales.
- Increased isolation and hiding behaviour.
- Loss of appetite.
To ensure a healthy breeding process, it is recommended to provide a balanced diet with high-quality flakes or pellets, live or frozen foods, and vegetable matter. Feed the female gourami more frequently, as she needs to provide nutrition for herself and her developing fry.
In conclusion, while Dwarf gourami females don't get pregnant in the traditional sense, they do become gravid with eggs, and it's important to provide them with the necessary care and conditions for successful spawning.

Signs of a gravid dwarf gourami include a rounded belly, changes in behaviour and colour patterns
In addition to physical changes, a gravid dwarf gourami may exhibit behavioural changes. She may become more reclusive or territorial as she prepares for the arrival of her fry, showing less interest in food. Her colour may also become more vibrant or develop dark spots as she prepares to lay eggs.
It is important to distinguish between a gravid dwarf gourami and one that is bloated. Bloating will cause more generalised swelling around the belly, and the fish may exhibit sluggish behaviour and a lack of appetite. If you suspect your gourami is bloated, you should take steps to address this issue, such as adding peas or frozen daphnia to their diet.
To confirm that your dwarf gourami is gravid, look for the following signs:
- Swelling in the belly, particularly underneath the front of her belly
- Stretched and pale scales
- Changes in behaviour, such as increased reclusiveness or territoriality
- Changes in colour patterns, such as more vibrant colours or dark spots on the belly

Gourami fry should be removed and put into their own tank immediately upon hatching
As soon as the gourami fry are swimming, they should be moved away from the male and placed in their own tank. This is to prevent the male from eating the fry, which is a real issue that can result in many of the fry not surviving. It is recommended to have a separate spawning/breeding tank for the fry, with water conditions similar to the community tank. The water level in the breeding tank can be dropped to about two-thirds full, making it easier for the male to pick up the fallen eggs and bring them back to the bubble nest.
The breeding tank should be smaller than the display tank, without any substrate on the bottom but with some floating plants at the water surface. A few small clay pots laid on their sides at the bottom of the tank will provide hiding places for the female, in case she needs to escape the attention of an overzealous male. The water temperature in the breeding tank should be maintained at around 78 to 80 degrees Fahrenheit. Filtration for the breeding tank is best provided by a mature air-driven sponge filter.
When moving the fry to the new tank, it is important to take your time and be gentle, as it can be tricky to move them. Leave them for about 30 minutes to acclimatise. If the pH, temperature, and other parameters are the same, the fry should be able to be gently added directly to the new tank. It is crucial to act quickly but carefully, as taking too long will stress the fry and could be fatal.
To ensure the best chance of survival for the gourami fry, it is important to provide them with the right food. Their first food should be infusoria, which can be grown at home by keeping small pieces of lettuce in jars of water and placing them in sunny areas. It takes a few days for the water to turn cloudy and then clear again, at which point the infusoria can be fed to the fry in small amounts. After about six or seven days, when the fry have grown a bit, microworms can be included in their diet, along with newly hatched brine shrimp nauplii. As the fry continue to grow, they can be gradually weaned onto crushed flake foods, but it is important to feed sparingly to avoid polluting the water.
In addition to providing the proper food and water conditions, it is also important to protect the gourami fry from potential predators. Ideally, gourami should be bred in separate breeding tanks without other tank mates. If this is not possible, a tank divider can be used to keep the fry separate from the adult fish.

To breed dwarf gouramis, you'll need a separate tank, a healthy breeding pair, and a water temperature of 82°F
To breed dwarf gouramis, you'll need to set up a separate breeding tank with specific requirements. Dwarf gouramis are bubble nesters, so the male will need space to build his bubble nest. Here are the steps to breed dwarf gouramis successfully:
Setting Up the Breeding Tank
Firstly, you'll need a separate breeding tank. This tank can be smaller than the display tank, around 10 gallons, with a water depth of about 6-8 inches. The water temperature should be maintained at around 80-82°F, which is slightly warmer than the typical temperature range for dwarf gouramis. Use a sponge filter to provide gentle filtration and add floating plants such as floating water sprite to reduce surface agitation and give the male a foundation to build his bubble nest. Some breeders also cover the tank with plastic cellophane to increase humidity for proper labyrinth organ development in the fry.
Conditioning the Adults
Before introducing the pair to the breeding tank, condition the adults by feeding them a diet rich in live food for about 7-10 days. This will ensure the female is ready to spawn and produce healthy eggs. During this time, you can also start infusoria cultures to feed the fry once they hatch.
Introducing the Pair
Once the male has constructed his bubble nest, it's time to introduce the female to the breeding tank. Within a day or so, the male will start courting the female by flaring his fins and displaying his brightest colours. The female might need some hiding places, such as small clay pots, to escape the male's attention during this time.
Spawning
When the female is ready to spawn, she will approach the male and touch him on the back or tail with her mouth. The male will then embrace the female, turning her on her side and then her back, at which point she will release her eggs, which the male will fertilise. The pair will repeat this process several times, with the male collecting any stray eggs and placing them in his bubble nest. After spawning, remove the female from the tank, as the male will guard the eggs aggressively.
Caring for the Fry
The eggs should hatch within 12-24 hours, and the fry will continue to develop within the protection of the bubble nest. After about three days, the fry will become free-swimming. At this point, remove the male from the tank, as he may consume the young. Feed the fry with tiny foods such as infusoria, powdered fry food, or vinegar eels for the first couple of weeks, and then switch to baby brine shrimp to promote healthy growth.
Other Considerations
It's important to note that finding a female dwarf gourami can be challenging, as most stores carry mainly male fish. Additionally, dwarf gouramis are susceptible to diseases, especially the Dwarf gourami iridovirus (DGIV), so ensure you purchase your fish from a reputable breeder and maintain excellent water quality to keep your fish healthy.

Female dwarf gouramis are very rare, so you'll likely need to buy from a breeder or place a special order.
When buying dwarf gouramis, it's important to observe them to ensure they are healthy. Healthy males will be sparring or observing other males. Ensure the fish you select do not have any ulcers on their bodies and that all fins, including the long feelers, are intact.
It's easy to tell the difference between male and female dwarf gouramis. The male is colourful, with a bright orange-red body and turquoise-blue, vertical stripes. The female, on the other hand, is not nearly as colourful, remaining a duller, silvery blue-grey. The male's dorsal fin is slightly longer and more tapered, compared to the rounder tip on the female.
When selecting a male and female pair, it's important to buy them from the same source, especially if they are going to be used for breeding.
If you are interested in breeding dwarf gouramis, you will need more than one fish aquarium. One aquarium is needed to hold the adult parent fish when they are not breeding, and another smaller aquarium can be used for breeding and rearing the fish.
Dwarf gouramis are generally peaceful fish, well-suited to smaller aquariums and community aquariums with other small, peaceful fish. They require plenty of vegetation, including floating plants that cover only part of the water's surface, as they need to access the surface to breathe air.

Frequently asked questions
Dwarf Gouramis do not get pregnant in the traditional sense, but they do become gravid with eggs. If the female's belly appears swollen, especially in one area underneath the front of her belly, this is a sign that she is carrying eggs. Her scales may also appear stretched and pale.
Pregnancy in Dwarf Gouramis is more localized in the front area of the belly and looks like a protruding marble or golf ball that has been swallowed. Bloating will create more swelling all around the belly.
A female Dwarf Gourami may become more reclusive or territorial as she prepares for the arrival of her fry. She may also show less interest in food.
Provide a safe and stress-free environment, a nutritious and varied diet, and monitor its health and behaviour. Ensure a suitable breeding partner and a proper tank setup to help prepare for successful spawning.
