The Japan Blue Double Sword Endler’s Livebearer is a vibrant and elegant Endler strain prized for its metallic blue coloration and distinctive double sword tail. Males display an iridescent electric-blue body contrasted by bright orange, yellow, or black accents depending on the line. The elongated upper and lower tail extensions create a graceful “double sword” appearance that adds constant movement and visual interest to planted aquariums. Active, peaceful, and full of personality, this strain is highly appreciated by nano fish and livebearer enthusiasts alike.
