Breeding and reproduction

Aphyosemion calliurum, commonly known as the Redtail Notho, is a fascinating species of killifish that inhabits the rivers and streams of West Africa. In this blog post, we will be exploring the breeding and reproduction habits of this beautiful fish. Breeding in Aphyosemion calliurum is an intricate and delicate process, which requires specific conditions and techniques to be successful.

The breeding season for Aphyosemion calliurum typically occurs during the rainy season when the water conditions are optimal. The males of this species are known for their vibrant colors and impressive tail fins, which they use to attract females. During courtship, the male will display his colorful fins and perform a series of courtship dances to capture the attention of the females.

Once the female is receptive, the male will guide her towards a suitable spawning site, which is usually a dense vegetation or moss. The male will then position himself next to the female and begin the spawning process. As the female releases her eggs, the male will simultaneously release his sperm to fertilize them. This synchronized release ensures a higher rate of successful fertilization.

After the eggs have been fertilized, the female will carefully deposit them in the chosen spawning site. Aphyosemion calliurum is an egg-laying species, meaning that the eggs will be left to develop on their own. The eggs are typically small, around 1-2mm in size, and will adhere to the vegetation or moss with adhesive threads.

Once the eggs have been deposited, it is important to provide the appropriate conditions for their development. The water temperature should be maintained around 73-77°F (23-25°C) and the pH level should be slightly acidic, around 6.0-6.5. It is also important to keep the water clean and well-oxygenated to ensure the best possible conditions for the eggs to hatch.

Breeding and reproduction:
Breeding season: Rainy season
Courtship behavior: Male displays colorful fins and performs courtship dances
Spawning process: Synchronized release of eggs and sperm, male guides female to spawning site
Egg deposition: Female carefully deposits eggs on vegetation or moss
Development conditions: Water temperature: 73-77°F (23-25°C), pH: 6.0-6.5

The incubation period for the eggs of Aphyosemion calliurum is approximately 14-21 days, depending on the water temperature. During this time, it is important to closely observe the eggs and ensure that they are healthy and free from any signs of fungus or contamination.

Once the eggs have hatched, the young fry will start feeding on small live or frozen foods such as micro worms, newly hatched brine shrimp, or finely crushed flake food. As they grow, they can be gradually transitioned to larger food sources. It is important to provide a varied and nutritious diet to support their growth and development.

In conclusion, the breeding and reproduction process of Aphyosemion calliurum is a fascinating aspect of this species’ life cycle. By understanding their breeding habits and providing the right conditions, hobbyists can successfully breed and raise these beautiful killifish. With their vibrant colors and unique behaviors, Aphyosemion calliurum is truly a captivating addition to any aquarium.
