Gourami marble (Trichogaster trichopterus) – content, breeding

Marble gourami (Trichogaster trichopterus “cosby / opaline”)

Marble gourami – a decorative look, obtained as a result of the crossing of blue and spotted gourami. Fishes with an unusual “marble color” were first discovered by an American Cosby.

It was he who brought the current view.

Habitat: Marble gourami is not found in nature, but its ancestors – blue gourami – inhabit the stagnant and slow-flowing waters of Indonesia, Thailand, Vietnam and Sumatra. Small fishes prefer reservoirs with dense, tangled vegetation through which the sunlight practically does not penetrate.

Description: The body of a marble gourami is oblong, oval, slightly compressed on the sides. Freakish dark specks of various shapes are scattered on the main silver-blue background, which give the fish a resemblance to a pattern on marble.

The ventral fins of a very peculiar form are threadlike in the form of tentacles. They went to marble goura from ancestors living in nature in dark and muddy water, where touch is necessary for survival.

The anal, caudal and dorsal fins are dark gray in color and are dotted with many yellow spots, the pectoral almost transparent.

It is difficult to distinguish a male from a female to puberty. In an adult male, the dorsal fin is sharper and elongated back; it is larger than the female.

Arrangement and parameters of the aquarium: for a pair, a 20-liter capacity is enough, but the content of 5-7 individuals in an oblong aquarium from 50 liters is preferable, always with a lid.

Gourami marble (Trichogaster trichopterus “cosby / opaline”) They look much better against a dark ground: small pebbles, granite chips, coarse sand. At the bottom there are several shelters made of clay shards, stones or snags.

Plantings should be very thick, but the foreground should be left open for swimming and viewing. Marble gourami suitable peristristis, elodeya, cryptocorynes, wallisneria, rogolopolnik, ekhinodorusy, Thai fern.

From floating plants – duckweed, riccia, pistis, salvinia.

Water parameters: 22-27 ° C, pH 6-7.5, dH 6-20.

Filtration with aeration is not a necessity, but gourami prefers clean water and the installation of the equipment is still desirable. Replacing 1/5 of the water is weekly.

Marble gourami are peaceful, calm and get along well with all other types of similar size.

Nutrition: food is not picky and takes all kinds of feed. Of the living – daphnia, bloodworm, brine shrimp, flies, coretra, tubule. From dry – Gammarus, Cyclops.

Marble gourams will eat bread and oatmeal crumbs, lettuce leaves and filamentous algae as vegetable components.

Reproduction: for spawning marble gourai will need an aquarium of 30-50 liters with plants (Thai fern, peristristist, ricia, duckweed), but without soil. To stimulate spawning, the temperature of the water in it rises by several degrees, the hardness 10, the acidity 7. The viewing glass closes.

A few weeks before spawning, manufacturers are kept separately and fed with live food.

The male builds a nest of about 8 cm in size from pieces of plants and air bubbles. Then he invites a female to him and, wrapping her around with his body, squeezes several eggs into the nest.

In a few hours of spawning, the female can sweep from several hundred to 2 thousand eggs.

During the incubation period, which lasts about 24-36 hours, the male takes care of the eggs and does not eat anything.

It is very important to monitor the stability of the temperature, as with its change, especially lowering, the male is able to destroy both the eggs and the nest.

Hatching fry can swim and eat on the 3rd day. At this stage, the hungry father’s parental instinct fades away and should be set aside. The water level drops to 6-10 cm until the development of the labyrinth organ in the fry.

We need a weekly substitution of half of the water and light aeration. You can start feeding infusoria, nauplii, rotifers.

Marble fry grow unevenly and are prone to cannibalism, so regular sorting is necessary.

Fish reach sexual maturity by 8-10 months.

Under favorable conditions Gourami marble (Trichogaster trichopterus) can live in an aquarium for a long time – up to 7 years.
