Natural habitat
Aphyosemion australe is a peaceful killifish native to marshy areas and shallow waters in Gabon, thriving in soft to medium hard water. They adapt easily to various water conditions, favoring subdued lighting and heavily planted aquariums.
Where they are found
These fish are often found in shallow waters where they feed on microinvertebrates. The dense plant life offers both food sources and protection against predators.
Aquarium care
Aphyosemion australe is well-suited for community tanks, preferring gentle water flow and slightly acidic to neutral pH levels. It requires a cover on the tank to prevent accidents but is not known to jump. Maintenance includes regular water changes and careful monitoring of water hardness to promote breeding success.
Feeding
A varied diet is essential for Aphyosemion australe, including high-quality flakes, frozen foods, and live foods. Juveniles particularly benefit from frequent, small feedings to promote healthy growth. Overfeeding should be avoided to prevent water quality issues.
Compatibility
Aphyosemion australe is peaceful and can coexist with similarly sized species like small tetras and rasboras. Care should be taken to avoid aggressive tankmates, which may harm the long fins of the males.
Breeding
Lyretail Killifish are egg layers, often spawning among dense plant cover. To encourage breeding, maintain separate spawning tanks with soft water and provide plenty of vegetation for eggs to cling to.
