Pearl gourami (Trichopodus leerii ) – a popular aquarium fish from the gourami family, also known as pearl gurami .


Mosaic gurami come from Asia . The species lives primarily in calm rivers and streams in Malaysia, Thailand, Borneo and Sumatra. There are now also populations living in Singapore and Colombia. Most of the fish traded come from farms in the Far East and Eastern Europe.

Characteristics and disposition

A very resistant and beautiful species, especially recommended for beginners. The spawning male is one of the most beautiful aquarium fish. Pearl gourami reaches 12 cm in length. Characteristic mosaic pattern bent on the body and fins. Body color between pink, orange and red shimmering silver with numerous bright spots spread all over the body.

Mature malescan be recognized by the more elongated anal (ending in threadlike appendages) and dorsal fins and the red discoloration of the throat. Calm fish, but males, however, during the spawning period are sometimes territorial and burdensome for the female, which should be provided with an appropriate number of hiding places. Fish have an additional organ – a labyrinth, thanks to which they can breathe the atmospheric air. Pearl gourami sometimes live up to 8 years.

Nutrition and feeding

They consume dry, live and frozen food.

They eagerly eat out of the aquarium, often undesirable hydra.


Pearl gourami feel best in a spacious aquarium, min. 100 liters. They like well-lit reservoirs with a low water level, heavily planted with vegetation and free space for swimming. They adapt quite easily to various water parameters, which, however, must be clean and regularly changed (10-15%).

It is necessary to use efficient filtration with a minimum forced water current so as not to damage the nest built among the plants. The mosaic gurami is one of the most peaceful of its kind. Perfect for a social aquarium. However, it is not advisable to combine it with much larger and aggressive fish.


Reproduction is easy.

The water level in the breeding aquarium should not be higher than 20 cm, and its movement should be moderate. Before the planned reproduction, the fish should be fed abundantly with live or frozen food. When the female becomes round, the male begins to build a foamy nest among plants, which are mostly floating. It creates foam for its construction by catching the air above the glass, which then spits out in the form of bubbles surrounded by mucus. After the construction is completed, he starts courtship in front of the female.

Then, together with the encouraged partner, it swims to the nest and spawns. The male embraces the female with his body, positioning himself under her and bending her body in the shape of the letter U. By maneuvering her pectoral fins, she turns with the female so that the female lies upside down under the nest. The male begins to hug the female and expels the milk onto the eggs she releases. The grains from the ground are collected by the male with his mouth and transferred to the nest, chasing the female at the same time.

When all the eggs are in the nest, the male lures the female again to perform another spawning act. Usually, during the entire spawning period, mosaic gouras lay about 200-300 eggs. After spawning, the female is chased away and should be separated. Hatching takes place after about 2 days, and after a few more days, the fry begin their independent journeys in search of food. During this time, the male should be fished out.

It is recommended to feed the young with protozoa, rotifers and micro-foods. Fish grow very slowly and are very sensitive to temperature fluctuations during the first 3 months.
