Description
The Blackfin Pearlfish is a striking annual killifish known for its iridescent blue spots on a dark body, native to temporary pools in South America. Males display vibrant coloration and can be territorial towards each other, especially during breeding. They have a short lifespan, typically less than a year, and require specific care to thrive and reproduce.
