Gourami pearl (Trichogaster leerii) – content, breeding

Gourami pearl (Trichogaster leerii) – a labyrinth fish of surprising color was discovered by the Dutch biologist Peter Blecker in 1852, and was brought to the USSR approximately in 1947-1949.

Habitat: lives in dense thickets of small reservoirs of India, Thailand, the Indonesian islands of Borneo and Sumatra, and the Malay Peninsula.

Description: compressed laterally, the elongated body of silver-violet color is dotted with light specks resembling pearls. The same spots are on the fins.

This feature of coloring and determined the name of the species. The back is yellowish-brown, and the fins are blue. Along the body is a dark stripe.

Breast and throat orange.

The abdominal fins, which are very sensitive organs of touch, are thin filaments. Anal fin extended from forked tail fin to anal opening.

Pectoral fins are colorless, transparent. The mouth is small.

The size Gourami pearl (Trichogaster leerii) in aquarium conditions does not exceed 11 cm.

The dorsal fin in males is longer and sharp; they are brighter and larger than females. The most noticeable sexual differences in the period of marriage games.

The pearls on the body of the male literally light up, and the chest and throat become scarlet.

Arrangement and parameters of the aquarium: A 60-liter aquarium will be enough for 7 individuals of pearl gourami. At the same time there should be more females to avoid the rivalry of males.

At the surface of the water, the air must be well ventilated and warm so that the fish will not catch a cold, therefore a lid is necessary.

Gourami prefers a bright light, but hitting the direct sun is undesirable. Coloring pearl gourami will play with side lighting.

As a soil for an aquarium, river sand of medium silting will suit.

The pearly gouram is a shy and shy little fish, for comfort it needs thickets of plants in which it can take refuge. For this fit valisneria, elodey and peristristis.

Floating plants, such as duckweed, are also permissible, but care should be taken that they do not cover the entire surface of the water, otherwise the fish will suffocate.

Water parameters: 25-27 ° C, PH 5.5-6.5, dH 5-10.

The substitution of the fifth part of the water is carried out weekly. Filtering is needed, but there should be no strong flow.

Gourami pearl (Trichogaster leerii) peace-loving, but it is quite difficult for him to find suitable neighbors in the aquarium. This is due to the special structure of its ventral fins, the strings of which other fish take for food, because of which gourami is attacked by species from the peaceful ones themselves.

Food: prefers live food, but from the dry and vegetable, too, does not refuse. At the heart of the diet – the pipeker, bloodworm, coretre, cyclop. Between spawning can be fed small crustaceans.

The fish have a very small mouth and the food must be crushed.

Reproduction: sexual maturity comes to 8 months, but fish older than a year may not give offspring at all.

To obtain full fry, dense plants of 20-40 liters with clear water are placed in a spawning aquarium and equipped with several shelters for the female.

Before spawning, future parents are kept separately for a week and feed on a pipe maker and a bloodworm.

The temperature in the spawning 28 ° C, pH 7, dH 4-8. Stimulates spawning by adding a third portion of distilled water.

In the aquarium for spawning, the male is first started, and after a few hours the female. The male builds a nest of pieces of Ricii and air bubbles, fastening the “building” with his saliva.

Then he invites the female to the nest and spawning begins. The male pops the eggs carefully into the nest.

Pearly gourami maloplodovity – no more than 200 eggs. Then the female leaves.

The incubation period depends on the temperature and lasts 24-48 hours. After a few days, the fry swim, and the male immediately settles, as he may confuse his offspring with food from starvation.

For fry, the water level drops to 10 cm before they form a labyrinth organ. You can install a light aeration, especially if a lot of fry.

At the initial stage, live dust and ciliates are taken; after 5 days, larger feed is acceptable.

Growth of pearl fry is fast but uneven, therefore large ones should be planted to avoid cases of cannibalism.

In aquarium conditions Gourami pearl (Trichogaster leerii) lives up to 7 years.
