Japanese Blue Sword Guppy

The Japanese Blue Swordtail Guppies are sold only as males since we cannot get the Thai breeders to ship us females. However, mate this impressive variety with diamond or blue delta female guppies and a few offspring will feature the distinctive swordtail. In a couple of years, maybe AquariumFishSale can buy the females from you.

Swordtail guppies do not get as large as some of the other varieties. These exotic aquarium fish stay closer to endler size.

Quick Facts

Care Guide

Tank setup: Give them a heater, a gentle filter and plenty of plants. Guppies like slightly hard water.

Feeding: Feed a quality flake or small pellet once or twice a day, only as much as they eat in a couple of minutes. They also enjoy frozen foods like bloodworms and brine shrimp.

Tankmates: Male guppies get along with other small, peaceful fish such as platies, mollies, corydoras, small tetras and rasboras. Avoid fin-nippers like tiger barbs, which go after their long tails, and larger fish that could eat them.

Good to know: Swordtail guppies have a pointed extension on the tail, like a small sword.
