The aquarium should be equipped with a loose-fitting lid or glass. The space under which should be well ventilated. Since the fish constantly need fresh atmospheric air. Glass or cover will prevent the entry into the above-water space of cold air swallowed which fish can get sick. The recommended distance to the lid centimeters five to eight. Lighting likes bright. It does not matter natural or artificial. Coloration in bright light is greatly benefited.


As a soil it is better to use coarse river sand of medium siltation. It is better to pour the sand in a layer of about five centimeters, so that any plants feel well.

It is necessary to constantly monitor, if they are interested in modified pelvic fins of our Nitenosets, it is better to drop them off.


It is better to feed live food. But it also eats dry food. The main thing is that the feed should be small.

Because of its anatomical features trichogaster can not consume large food. The best delicacies for him small moths, cut trubichnik. Between spawning, you can treat small crustaceans. However, it should not be accustomed to such food.

Pearl gourami breeding

In general, Trichogaster leerii breeding is the same as other trichogasters and spawners in general. But there are some peculiarities. At elevated temperatures in a common aquarium, they can start spawning right there. The entire litter is likely to be subsequently eaten by neighbors and the producers themselves. But such spawning is still a positive side, namely, the female will avoid the formation of cysts, which preserves her ability to reproduce.

To obtain a normal litter, its preservation for spawning should certainly be prepared. In gourami pearl breeding is best provoked in late spring or early summer, when feed will be easily available. Especially small – infusoria, live sifted dust.

Training of producers

A week to two weeks before the proposed breeding males are separated from females. During the pre-spawning period, they are abundantly fed live feed – moths, trubichnik. Crustaceans (live daphnia) before spawning should not be fed. The habit of chasing after the pudgy little thing can end up eating eggs, and then fry.

Preparing the spawning ground

For spawning is suitable aquarium for 20 – 40 liters. The bottom is desirable sandy, on which it is desirable to arrange several cozy shelters in which the female could hide from overly persistent courtship of his beau. These shelters can be built from large stones or from the shards, not used pottery pots. The spawning ground should be densely planted with plants, among which the female can also find shelter, if necessary.

There should be a bunch of riccia floating on the surface. The future daddy uses it to build the nest. The slightest stress factor can drive the daddy to frenzy in a burst of which he is able to destroy the nest together with the offspring. Therefore, it is obligatory to have a heater with a thermostat. That would prevent temperature fluctuations. All sight glasses, near which sharp movements are possible, are closed from the outside with paper. Water should have a hardness of 4 to 8 °dH. The total hardness can be lowered by adding one-third part distilled water. The water should be clean, freshly tempered. pH – 7.

Pearl gourami Spawning stimulation

Spawning is stimulated by increasing water temperature to 28 ° C. In the spawning tank prepared in this way, first settle the male, and a few hours later planted to him his girlfriend. Set the thermostat heater at 28 – 30 ° C. Finding himself in the middle of such a “gouramyeh paradise”, the male acquires a bright mating color and in this parade form is taken for the construction of a nest of air bubbles using plates of richchia. Construction lasts about a day. Sometimes becoming a long construction, can stretch to three days. The lady does not take part in the construction, she controls the process from afar.

After the nest is ready, the cavalier invites the female under the nest, where the spawning begins. It lasts about two hours. During this time the female hatches up to two hundred eggs, which the father, having fertilized with his milk, places between the bubbles of the nest.

After that, the care of the offspring falls on the father. If the mother is allowed, she can help him, but if the father shows aggression towards her, it is better to carefully fish her out and drop her off.

The care of the fry falls to the aquarist

The incubation period lasts 24 – 48 hours. And after two to three days, the fry will swim and spread throughout the aquarium. Daddy must be urgently removed. Starving (during spawning male almost nothing to eat), starting to get nervous because of the ungrateful behavior of children, he can lose the paternal instinct. Nothing good will come out of this.

After you drop off the male, the water level should be lowered to 10 centimeters. Maintain it this way should be about three weeks, until the fry will form a maze. If there are a lot of fry it is desirable to establish low-flow aeration. The first three to five days fry should be given infusoria or the smallest living dust. The next week they can be transferred to larger feeds. Temperature can be lowered only after a month and a half. Under good conditions, abundant feeding fry grow quickly, but not evenly. Be sure to sort them by size.

Trichogaster leerii is a rather fastidious fish. But its magnificent coloration and majestic appearance make it very attractive to many amateurs and professionals. It is difficult to pick up her neighbors. It is very heat-loving, not many species will withstand such a constant heat. Those who can exist at such temperatures can begin to oppress the peaceful trichogaster, chasing his pelvic fins – whiskers.
