How to care The Ceylon Killifish
The Ceylon Killifish (Aphyosemion ceylonicum) is a colorful and captivating species native to Sri Lanka, located in South Asia. It is highly valued by aquarists for its striking coloration, particularly the males, which showcase vibrant hues of orange, red, and blue, creating a beautiful contrast against the more muted female coloration. Males can grow up to 2.5 inches (6.5 cm), while females tend to remain slightly smaller. This species, like many other killifish, has a unique appearance that makes it a standout in an aquarium setting.
In the wild, the Ceylon Killifish is typically found in shallow, slow-moving streams and temporary pools. These habitats are usually rich in aquatic plants and organic debris, which provide both shelter and breeding grounds. The species is adapted to survive in these ephemeral water bodies by laying eggs in the substrate or plant matter, which will hatch when the water level rises after seasonal rains.
For aquarium care, the Ceylon Killifish requires stable water conditions to thrive. A minimum tank size of 10 gallons (38 liters) is sufficient for a small group, but larger tanks may be needed if you wish to keep multiple pairs or other species. The water should have a pH between 6.5 and 7.5, a temperature range of 75-80°F (24-27°C), and a hardness of 8-15 dGH. Keeping these parameters consistent is essential for maintaining the health and vibrancy of the fish.
The Ceylon Killifish is carnivorous, and its diet should consist mainly of live foods such as brine shrimp, bloodworms, and daphnia. High-quality pellets and flakes can be fed as supplementary food, but live foods are crucial for maintaining their optimal health and coloration. Due to their territorial nature, it is recommended to keep a 1:2 male-to-female ratio in the aquarium. This reduces the likelihood of aggression among males, especially during the breeding season.
Breeding the Ceylon Killifish is relatively simple, as they are prolific egg layers. The eggs are typically laid in fine substrates or among aquatic plants, and they hatch in about two to three weeks. The fry are small but grow quickly, making it easy for the breeder to raise them. With a lifespan of 2-3 years, the Ceylon Killifish can be a rewarding and long-lived addition to a freshwater aquarium.
This species is not commonly available in pet stores, but it can be sourced from specialized breeders or online retailers. With the proper care and attention to water quality, diet, and breeding conditions, the Ceylon Killifish can thrive and add vibrant color to your aquarium.
