Gourami moonfish labyrinth fish, so it can be in an environment with a low content of dissolved oxygen, but it is still better to provide a weak additional artificial aeration. The air pumped by the compressor through the water will moisten and heat. Thanks to this under the cover of the aquarium will accumulate moisturized warm air.

The water level should be about fifteen centimeters. Its temperature should be maintained between 24 and 26 degrees Celsius. The hardness should be about 10°dH. Reaction pH 7. On the surface of the water throw floating plants such as cassava, pistia, riccia. The male uses them to build a nest. The nest is usually large. Its diameter can reach fifteen centimeters, sometimes even more. The nest may rise about one and a half centimeters above the surface.

When the nest is ready, the breeders position themselves under the nest. The male wraps his body around the female’s abdomen and turns her over with her abdomen toward the nest. In this position, she hatch a portion of eggs. The male picks up the fertilized eggs with his mouth and places them in the nest.

This dance lasts for several hours. During this time, the female, depending on her readiness, can hatch from three hundred to five thousand eggs. After the end of spawning female should be removed. Further care of the offspring falls on the father. He takes care of the nest. Replaces the eggs that have fallen out. Adds air bubbles if necessary.

Caring for fry

Incubation lasts about two days, and after another two to four days the fry will swim. Now from the spawning ground should be removed and daddy. The water level should be lowered to ten centimeters. This level should be maintained until the fry have not formed a labyrinth, and they begin to breathe atmospheric air. Starter food for fry – infusoria, small zooplankton. As the young grow, they should be transferred to larger types of food, as well as sorted by size, so that the larger tomboys do not oppress their smaller brothers.

The moon gourami is a very beautiful fish. Despite its large size, can be kept in a common aquarium, as it has a fairly peaceful disposition. Still, it is better for him to equip a species aquarium, although it will require some additional space. I hope you liked the new acquaintance.
