Description
The Bluish-tail Pearlfish, or Rachov's Killifish, is a stunning annual killifish known for the male's vibrant blue-green fins and iridescent spotted body. These short-lived fish typically live less than a year and are highly sought after by killifish enthusiasts for their unique breeding cycle. They require specific care due to their annual nature and preference for soft, acidic water.
