Description
Austrolebias nigripinnis is a beautiful annual killifish from South America, known for the males' striking iridescent blue-green bodies and dark fins. These fish are adapted to temporary pools, laying eggs in substrate that can survive dry periods. They are best kept in a species-specific setup due to their unique life cycle and temperament.
