The Black Moscow Guppy (Poecilia reticulata var. “Black Moscow”) is one of the most striking and popular guppy varieties. This beautiful guppy displays solid black coloration with elegant, long tails in males and is sure to be a standout in any aquarium! We are pleased to now offer male/female pairs of this fish so that you can start your own little colony if you wish. Females of this variety are rare and can often command a hefty price.
