Honey gourami – Breeding and rearing

The honey gourami, honey gourami, originally comes from the mineral-poor waters of India. To impress the female, the male performs many tricks during the mating dance in the aquarium. This fish, which is suitable for beginners, impresses with its interesting behaviour.

A small, densely planted aquarium is required for keeping and breeding the fish. An additionally darkened back wall and several floating plants give the fish a feeling of security. For breeding, the water level is reduced by half. The temperature of the aquarium water must be increased up to 28 to 30 degrees Celsius.

In order to prevent cooling on the surface, the aquarium is covered with a glass pane. The ventilation is also turned off. The water should be soft and slightly acidic. If the conditions in the aquarium are optimal for breeding, the male fish will build a nest of bubbles and plant parts. The nest, which can be up to 40 cm in size, remains particularly stable if it is built directly under a floating leaf.

Environmental conditions for breeding

  • small aquarium with 10 cm water level
  • soft water
  • PH value 6,5 to 7,5
  • Temperature 28 degrees Celsius
  • Soil and floating plants

The courtship behavior

The male begins to hunt the female. Again and again he stands upright with his head pointing upwards, waves his body and swims in the direction of the foam nest. Once the male has lured the female into his nest, mating takes place.

Spawning behaviour

Once the female has been successfully lured to the foam nest, she is embraced by the male. The spawning occurs. The fish lay up to 500 eggs, which are 1 mm large and yellowish in colour. Through an oily film on the surface, the eggs rise to the foam nest in the water. After 24 hours the black fish larvae hatch.
As soon as the foam nest has been removed, the male starts a new nest building. The fish are permanent spawners

Breeding care and feeding

If the male is left in the rearing tank, he guards the foam nest for another four days until the small fish leave it. In order to raise the young fish, the foam nest can be carefully skimmed off and placed in a separate rearing tank. In order to make the rearing tank easier to clean, there should be no bottom gravel. For cleaning, snails are placed in the rearing tank and the food residues are removed. The excrement of the snails can be carefully sucked off with an air hose. The first three days after hatching the young fish feed on the yolk sac. Afterwards they have to be fed. At the latest three days after hatching, the parent fish must be removed from the tank, otherwise they will eat the young fish.

Rearing of young fish

If the young fish swim around freely, liquid feed, slippery paramecia and microfine rearing feed are used for feeding. After one week the young fish will also eat food with larger components. The fast-growing young fish can be fed with pond food and artemia nauplii.
