Habitat: inhabits shallow mountain rivers, rice fields and silted puddles of Cambodia, South Vietnam, Laos, Thailand and Sunda Islands.

Description: elongated body is compressed from the sides, body height is much lower compared to other types of gourami. Color bluish-green, light belly.

From the eyes to the tail there is a dark stripe, slightly above the row of dark specks almost merging into a stripe.

The shape of the fins is pointed, and the dorsal is sail-like. All fins, except for transparent ventral and chest, blue with a scattering of tiny red dots, on the edge is a blue edging.

Eyes with red and blue highlights. The mouth is large, on the gill covers of the notch.

The labyrinth of the dwarf gourami is poorly developed.

Males have a bright color, large size and elongated fins – anal and dorsal.

The size of the fish usually does not exceed 3-4 cm.

Arrangement and parameters of the aquarium: the timid nature of the dwarf gouries requires keeping a flock of 8 individuals in small tanks of 20-25 liters with thick-leaved plants, for example, Anubias and cryptocoryne, bark logs and a sufficient number of shelters. As with all labyrinth aquariums, be sure to cover with a lid to maintain warm air at the surface.

The soil should be dark, shallow and slightly silted. The lighting is bright, but indirect, diffused light helps to create floating plants. Such species as ichiya and duckweed should be limited to floating contours, otherwise they will grow to the entire water surface and the fish will suffocate.

Lateral illumination emphasizes color Dwarf Gourami (Trichopsis pumila).

Pumilus are very thermophilic and at low temperature or its vibrations begin to ache, losing appetite and becoming sluggish. Often colds cause the death of fish.

Save the situation can be enhanced nutrition and a gradual increase in temperature.

Water parameters: 24-28 ° C, pH 6-7, dH 5-12.

A third of the water is replaced with fresh weekly. Filtration is desirable, but moderate, dwarf gourami does not like water fluctuations.

Neighborhood with the same tiny and peaceful neighbors gives Pumil confidence. Comfortable for dwarf gourami will be content with characteristic fish, honey gourami and shrimp.

Nutrition: It is necessary to make ration of dwarf gourams from live feeds – moth, cyclops, corets, microplankton, tubule. Fish also do not refuse dry food, the main thing is to chop them thoroughly, because the pumil has a very small mouth.

Reproduction: spawning is stimulated by the separate content of producers for 2 weeks, feeding with live food and increasing temperature.

Water parameters in the spawning aquarium: 26-30 ° C, dH up to 10 °, pH 6.5-7.0.

The water level in the 15-liter spawning should be a maximum of 20 cm, large-leaved and floating plants are needed, the soil is not required.

Male builds a foam nest not under the surface, but under a large sheet. The female is not very prolific, capable of sweeping no more than 400 eggs, mostly much less – up to 150.

After spawning, it settles.

A unique feature of spawning of dwarf gourami is the egg pack, which contains 4-6 eggs of white-yellow color. Father’s task is to open all the packages and place the eggs in the nest.

Incubation lasts approximately 36 hours. After hatching the fry, the male transports them closer to light and heat, and returns them to the nest in the evening.

The father’s instinct disappears from his father for 2-3 days, he leaves the nest and at this moment it must be planted.

The fry were dark-colored, very tiny (1.5 mm) and sedentary. Able to swim and eat on the 4th day.

Initial feed: rotifers, egg yolk, ciliates. Grown fry can be fed with nauplii cyclops and artemia.

The main condition for the successful cultivation of dwarf fry is to maintain the temperature without hesitation and regular feeding.
