You are bidding on a juvenile pair of Japan Blue Double Sword tail guppies. The Japan Blue Gold Double Sword Guppy (Poecilia reticulata "Japan Blue Gold Double Sword") is a relatively new color strain that has only very recently become available. Its vibrant coloration and outgoing personality make it a great addition and centerpiece fish for almost any community aquarium. Its sky blue and yellow coloration is nearly unrivaled. While it is rare, the Japan Blue Gold Double Sword Guppy has quickly become a popular fish for the nano or planted aquarium, particularly due to its small size, which makes it an excellent cohabitant for adult dwarf shrimp.
