Breeding and reproduction of Belontia hasselti

The breeding and reproduction of Belontia hasselti, also known as the Red Belonti or Red Indian Fighter, is a fascinating process that can be quite rewarding for fish enthusiasts. Belontia hasselti is a species of gourami native to the freshwater rivers, streams, and ponds of Southeast Asia. In this blog post, we will explore the various aspects of breeding and reproduction in Belontia hasselti and provide some valuable tips for successfully breeding these beautiful fish.

Belontia hasselti has a unique reproductive behavior compared to other gourami species. During the breeding season, males will display vibrant colors and develop an elongated dorsal fin. They become territorial and fiercely protect their chosen spawning site. The females, on the other hand, become plumper and display a rounder belly. To encourage breeding, it is essential to maintain ideal water conditions and provide suitable breeding setups.

One key aspect of breeding Belontia hasselti is the selection of compatible pairs. It is crucial to provide a balanced ratio of males to females in the breeding tank to prevent excessive aggression and stress. The tank should have plenty of hiding spots, such as rocks, caves, or dense vegetation, where females can seek refuge if needed. The use of floating plants like Amazon frogbit or Indian Water Fern can create shaded areas and mimic their natural habitat, promoting spawning behavior.

During the breeding process, the male Belontia hasselti builds a bubble nest on the water’s surface using saliva and plant material. The female will then be enticed by the male’s elaborate courtship display, which includes flaring fins, vibrant colors, and chasing behavior. Once the female is ready to deposit her eggs, which can range from 100 to 300 eggs, she will join the male under the bubble nest.

After the female releases the eggs, the male will quickly fertilize them, and they will float up into the bubble nest. The male will guard the nest diligently and ensure that any fallen eggs are carefully placed back into the nest. It is crucial to remove the female from the breeding tank after spawning to prevent her from eating the eggs. Maintaining optimal water conditions, including appropriate temperature and water quality, is vital for the successful development of the eggs.

Within 24 to 48 hours, the eggs will hatch into fry, and they will remain in the bubble nest for several days until they become free-swimming. At this point, the fry will need to be fed with appropriate size and nutritious food, such as newly hatched brine shrimp or commercial fry-specific diets. Regular water changes and monitoring of water parameters will help ensure the healthy growth and development of the fry.

In conclusion, breeding Belontia hasselti can be a rewarding experience for aquarium hobbyists. By understanding their natural behaviors and providing suitable breeding setups, enthusiasts can successfully breed and raise a new generation of these beautiful fish. It is essential to pay attention to water conditions, tank setup, and compatible pairs to increase the chances of successful breeding. With proper care and attention, you can witness the remarkable process of life unfold within your own home aquarium.
