About Idle Fish Tank Tycoon

Idle Fish Tank Tycoon is a casual aquarium manager simulator that blends idle gameplay, tycoon mechanics, and clicker-style progression. Starting with a small aquarium in San Francisco, the journey expands across the globe by opening new franchises, upgrading fish tanks, and collecting unique fish species. Each aquarium generates income over time, allowing the steady growth of a profitable empire even while away from the game. 

Build a Global Aquarium Empire

The adventure begins with a modest fish tank and grows into a worldwide aquarium business. New locations unlock across different countries, each offering new fish to collect and new opportunities to increase profits. Opening franchises boosts fame and income, transforming a single aquarium into a powerful global empire. Filling fish tanks and improving their efficiency plays a key role in maximizing earnings and accelerating growth.
