Features & Capabilities

RYUKIN – Gracefully Fluttering Goldfish brings a serene, interactive aquarium to your Chrome browser. Watch goldfish glide with graceful fins as you touch the screen, customize the tank, and enjoy calming water visuals and sounds. Safe for kids with a Cat & Baby Mode, sleep timer for bedtime, and the option to play your own music while you watch.

Customize every detail—from tank shape and background color to floating objects and water effects. Fine-tune camera options, tilt sensitivity, orientation, brightness, and color tone, and display up to six fish at once. White and black goldfish are included with themed options via in-app purchases. This project honors a childhood dream inspired by Wa Kingyo, refined over years to bring the allure of goldfish closer.

The thought put into customization pays off well - the experience goes above and beyond for immersion; I will always keep it open as my 2nd wallpaper. I might never buy a real fish tank after this

highly recommend this app to relax or have on ipad on background while drawing/working, dev if you're reading this please make bundles to buy the fish instead of individual purchases, awesome job 👏
