Japanese Blue Mosaic Guppy | Poecilia Reticulatus

Japanese Blue Mosaic Guppy

The Japanese Blue Mosaic Guppy (Poecilia reticulata) is a stunning freshwater fish that is sure to grab attention in any aquarium. As one of the most visually striking guppy varieties, males exhibit a dazzling mosaic of blue, purple, and silver colors across their body and flowing fins. Females are less ornate but still beautiful with steel blue and silver hues.

Japanese Blue Mosaic Guppies are peaceful community fish that do best when kept in schools of 6 or more. Males can be kept together, but it's best to maintain a ratio of 2 females per male to disperse male aggression. They make an excellent addition to larger community tanks of 20 gallons or more that are well-planted and have plenty of swimming areas. Their small size of only 1-2 inches also allows them to be housed in desktop nano aquariums.
