Successful breeding is only possible in a separate spawning aquarium. This will protect not only the fry from potential predation in the community tank, but also other inhabitants who may suffer from an aggressive male Flame Gourami fiercely guarding the clutch. A spawning tank of 20 liters or more will be sufficient, and the water parameters in it should be identical to the conditions of the community tank. The standard set of equipment for a spawning tank includes a lighting system, an aerator, a heater, and a simple sponge filter. The setup must include rooted and floating plants with small leaves. The stimulus for spawning is enhanced feeding with meat products: bloodworms, insect larvae, or frozen food should be added to the daily diet. Under favorable conditions, the female will begin to fill with eggs, which will manifest as a noticeable increase in her abdomen; at this point, she is transferred to a separate tank. The male is introduced only on the second or third day. All transfers are recommended to be carried out in the dark to minimize stress for the fish. While the female is developing eggs, the male begins to build a nest on the water's surface. The Flame Gourami approaches this process thoroughly, using not only air bubbles but also various aquarium materials (small twigs, pieces of leaves, roots, etc.). Upon completion of construction, the mating ritual begins: the male swims around his chosen partner, inviting her to the nest and touching her with his mouth. The female can lay up to 800 eggs, after which she should be immediately returned to the community tank. The male remains near the nest to guard the clutch, and at this time becomes quite aggressive, even towards the female. The fry hatch within 24 hours and begin to swim freely on the third day, which signals the removal of the male from the spawning tank.
