Description
Austrolebias nigripinnis is a small, annual killifish native to temporary pools in South America. Males display iridescent blue-green bodies with black spots and fins, while females are more subdued. They are known for their unique breeding cycle involving eggs that can survive dry periods, and males can be territorial towards each other.
