Goldfish Days: Zen Aquarium

■ Turn Your Drawings and Photos into Swimming Goldfish!

What if your cat became a goldfish?
What if your child’s doodle started swimming?

Kingyo Biyori is a relaxing aquarium game where you can create one-of-a-kind goldfish from your own drawings and favorite photos.

Watch your creations swim around the tank, grow over time, make friends, and even have offspring of their own.

Build a peaceful aquarium filled with goldfish that exist nowhere else in the world.

■ Create Your Own Original Goldfish

Design goldfish with the built-in drawing tools, or import your favorite photos.

Pets, illustrations, landscapes, food—almost anything can become a goldfish.

Share your creations on social media and show off your favorites to friends and family!

■ Every Goldfish Has Its Own Personality

Collect over 16 varieties of goldfish, including Common Goldfish, Black Moor, Ranchu, Comet, and more.

Each fish has its own unique personality, behaviors, and preferences, making every one feel special.

■ Raise and Care for Your Goldfish

Feed them, pet them, and watch them grow.

Even when you're away, your goldfish will continue swimming happily in their aquarium.

■ Watch New Generations Be Born

When two goldfish become close friends, they may produce a Friendship Egg.

The baby goldfish inherit traits and appearances from their parents, creating new and unique combinations.

Grow your own family of goldfish across multiple generations.

Customize your aquarium with aquatic plants, driftwood, rocks, backgrounds, gravel, lighting, and more.

Create a beautiful underwater world that reflects the season, your mood, or your imagination.
