The Complete Guide To Caring for Dwarf Gouramis: Tips for Healthy and Happy Fish

Dwarf gouramies (Trichogaster Lalius) are pretty freshwater fish native to Southern Asia (Bangladesh, Pakistan, and India). These tropical fish are formerly known as Colisa Lalia.

They are commonly found in rice fields, ponds, slow-flowing rivers, and lakes across Southern Asia. Now, these fish are available in almost all countries, including the United States, the United Kingdom, and Singapore.

These exotic fish have become popular among fish hobbyists, and many breeders crossbreed them to produce beautiful iridescent and patterned varieties.

Dwarf Gourami Appearance

These freshwater fish species can grow up to 3 ½ inches long (8.8 Cm). But, there’s a report that they can grow larger in the wild.

In the aquarium, male dwarf gouramies generally grow to only 3 inches. Meanwhile, females can reach 2.4 inches in growth. So, a nano aquarium is suitable for them.

In their habitat, male gouramies have diagonal stripes of alternating red and blue, while females are silvery. The male has pointed dorsal fins, and the female has curved or rounded dorsal fins. Selective breeding in captivity has increased the coloration of this tropical river fish. We found them in solid colors like powder blue gourami and red flame, as well as other dwarf gourami varieties, at the fish store.

These fish can live 4-6 years, but with proper care, they can live longer. They are labyrinth fish, which means they breathe air. So you will see them rise to the water surface to take air frequently.

Caring For Dwarf Gouramis

They are also suitable for aquascaping. You could put them in a tank with another freshwater fish species as a community.

At least use a 10-gallon (45 liters) aquarium to keep them with other small fish, such as mollies, tetras, guppies, ghost fish, loaches, platies, rasboras, assassin snails, ramshorn snails, and apple snails. If you want to keep them in the communities, use a larger aquarium.

10-20% weekly water changes are enough to keep these dwarf gouramies healthy and thriving.

The optimum temperature for these fish is between 22 to 27°C. Adding rooted aquarium plants, floating plants, and driftwood will create shady areas for these fish to hide and play.

Please don’t keep them together with large or aggressive fish, such as betta fish. It may intimidate or attack the dwarf gouramis.

They are a pretty hardy fish and can live in water with a pH between 6.5 – 7

Common Diseases Affecting The Dwarf Gourami Fish

Dwarf gourami iridovirus is one of the diseases commonly associated with them. This virus’s symptoms include loss of color, lethargy, lesions and sores, abdominal swelling, loss of appetite, and sudden death.

This infectious disease spreads quickly from one fish to another if you don’t quarantine the affected fish immediately.

Sadly, until now, there is no treatment for this deadly disease. Most dwarf gouramis infected by this virus eventually die.

But you can avoid it by maintaining water quality through a good filtration system and regular water changes.

Dwarf Gourami Feeding and Diet

The freshwater dwarf gourami is an omnivore. They tend to prefer meaty and algae-based food. In the wild, they commonly feed on small invertebrates, algae, and other smaller creatures.

You could feed them fish pellets or algae-based flakes, along with brine shrimp, tubifex worms, or freeze-dried bloodworms. It will offer these fish good nutrition.

How To Breed Dwarf Gouramis

Reducing the water level to 6-8 inches and raising the water temperature to 28-30 °C (86 °F) will trigger spawning.

The vegetation is essential at this point. The male gourami creates the bubble nest from aquarium plant materials, then binds it together with bubbles.

Their nests are very complex and robust. It can reach several inches across and an inch deep. Adding some Riccia Fluitans, Vesicularia Dubyana, Vallisneria Contortionist, and Limnophila to the tank breeding will be helpful. Adding some peat fiber can be a building material for them.

After the male builds the nest, generally in the afternoon or evening, he will start courting the female. When the female accepts the male to spawn, she will touch his back or tail with her mouth.

After that, the male will embrace the female, turning her first on her side and the last on her back. At this moment, the female will release the eggs, which the male will immediately fertilize.

Almost all of the eggs are floating up into the nest. At the same time, the male will collect the stray eggs and put them into the nest. If all the eggs are secured in the nest, they will spawn again.

If you keep more females than males in the breeding aquarium, the male gourami will spawn all of them. The spawning sessions usually take 2-4 hours and produce between 300 and 800 eggs.

Once the spawn is completed, the male gourami will place a smooth layer of bubbles under the eggs. It will provide greater security and ensure the eggs remain on the nest.

At this moment, you should remove the female dwarf gourami, as the male will be too aggressive, or vice versa.

The male will protect the eggs until they become fry. Eggs usually hatch in 12-24 hours. After 3 days, the fry will be free-swimming and leave their nest. At the same time, you should remove the male to avoid him consuming the young dwarf gourami.

The fry dwarf gourami could be fed infusoria, then brine shrimp or daphnia.
