Male and female dwarf gourami


Many gourami species, especially dwarf gourami in nature, can be found in the waters of Bengal and Assam. They can reach a size of 6 cm or 2.5 inches. The body is dotted with small, alternating lines of blue, red, green, and yellowish hues. To distinguish between male and female dwarf gourami, continue reading.

Male and female dwarf gourami

Male and female dwarf gourami can be distinguished by the dorsal fin, size, and colors. In male dwarf gourami, the dorsal fin is elongated and pointy, and the female dorsal fin is smaller and rounded. Females are a bit shorter in size than males. Male dwarf gourami have more vivid and beautiful colors than females, especially during the spawning period.

The female dwarf gourami is much dimmer, in some cases-Gray, with slightly noticeable color features of these fish. The male has a pointed dorsal fin, while the female has a rounded shape. All fins except the pectoral fins are covered with red dots and lines.

You can breed the gourami both separately and in general aquariums. If you are going to increase the number of water changes and water temperature, you will stimulate dwarf gourami breeding.

Breeding Gouramis 2nd Time with Closeup of Eggs and Fry

Dwarf gourami

Many Anabantoidei are common in the waters of India. These are representatives of the family, whose peculiarity is the presence of a labyrinth organ allows fish to live in oxygen-poor water. Dwarf gourami fish catch air bubbles from the water surface through the mouth and then in the gill arches, in the System of mazes, the blood vessels of the mucous membrane are enriched with oxygen this way. This allows the dwarf gourami fish to usually exist in a low-oxygen environment and be moist in the air without water for several hours. In a closed container without access to the water surface, gourami can live a couple of hours.

Dwarf gourami are not born with a labyrinth organ. They develop it in the second or third week after the hatching from the eggs. The period of formation of the labyrinth in juvenile fish is the most difficult process for them during which the weak die. The care for adult fish is not difficult. In general, they feel good and develop fast in well-maintained aquariums, densely planted with plants, with an average light and water temperature of 73 to 81 Farenheight or 23-27°C.

These dwarf gourami’s body size and structure vary from 3 cm to 6 cm and 1.5 to 2.5 inches in length. All Labyrinth fish are similar in their spawning behavior. An increase in temperature and frequent water changes cause these fish to start breeding behavior.


To breed dwarf gourami, it is necessary to prepare a container for 5 to 8 gallons or 20 to 30 liters with a water level of 6 inches to 15 cm. If you want to breed dwarf gourami, you should have s separate spawning fish tank. Female dwarf gourami needs many plants or decorations to hide and some plants like duckweeds on the water surface so it would be easier for the male to build a nest. You can use the Java moss plant by tying a thin nylon thread to the edge of the aquarium so that it is in the upper water layer. Ensure the water current inside an aquarium is not strong enough to not destroy the nest.

Before spawning, the female dwarf gourami is kept separate from the male, and when her belly is noticeably plumper, planted in the spawning aquarium to the male. The spawning temperature should be increased to 82 to 84 Farenheight and 28 to 29°C. 

After putting a pair in a separate fish tank, the male begins to build a nest: the male blows bubbles with air and saliva and uses it to build a nest. Also, floating plant parts are collected with the mouth and transferred to the spawning site. Construction takes a long time, sometimes all day. The mating games start when the nest of plants and bubbles is finished. The male quickly jerks towards the female on the side, inviting her to spawn with peculiar movements. Driven by the male, the female gets under the nest, the male wraps around her, squeezes her body and helps to eject part of caviar. At the same time, fertilization takes place. It can take a couple of cycles for the female to lay full caviar.

After spawning, the female no longer obeys the male. The male can damage her, so it is better to deposit her away immediately. Otherwise, she can die. The male takes care of the eggs, jealously guards, and cares for the nest.

When fry hatch, they are extremely small. At this time, it is better to remove male dwarf gourami back to the general aquarium. Dwarf gourami fry are fed “live dust” or egg yolk. In the second week of life, you can feed them with small Cyclops. At the age of 8 to 10 months, the fish become sexually mature.
