Japanese Blue Lyretail Guppy
A perfect starter fish for beginners, the Japanese Blue Lyretail Guppy is a peaceful and social species ideal for community tanks. These livebearing fish release live fry rather than laying eggs, making them a great choice for those interested in breeding.
Known for their elegant lyretail fins, these guppies display a striking electric blue hue that contrasts beautifully with their silver or tan front bodies. The body may feature spots in red, green, or black, adding visual interest.
It is recommended to keep more females than males to avoid stress, as males may exhibit persistent mating behaviors that can be overwhelming for females.

The guppies are vibrant and active. I kept 5 fish with a 3:2 female-to-male ratio, and they’ve been peaceful. The blue tails stand out in the tank and the fry appeared after a few weeks. Easy to care for and a great addition to a community setup.

Beautiful fish with strong colors. I noticed the spots on their bodies vary slightly between individuals. I kept more females to avoid male aggression, and it worked well. They seem healthy and active in a 20-gallon tank.

Perfect for beginners. The electric blue lyretails are eye-catching. I didn’t expect them to breed, but I saw live fry after a month. The tank remains balanced and the fish don’t fight much with the right ratio.
