About MioAquaria

Mio Aquaria is a cozy sandbox aquarium management game set in a whimsical world of water. Build your aquarium from nothing, care for fantasy aquatic creatures from across the world, and lead a team of cat staff as you rise through the ranks to become the world’s greatest aquarium.

Core Challenge

Design freely, explore the depths, and solve the core challenge of Mio Aquaria: balancing the needs of aquatic creatures and cats to create a thriving, attractive aquarium.

🐠 Build and Customize Your Aquarium

Create your aquarium your way using sandbox-style construction. Build spaces, place facilities, and design tanks that balance water quality, temperature, and creature compatibility.

Hosting a diverse mix of aquatic creatures increases your aquarium’s attractiveness — but only if their needs are met.

🌊 Discover Fantasy Aquatic Creatures

Explore the world to discover new resources, materials, and new inhabitants for your tanks. The creatures of Mio Aquaria are inspired by real aquatic life, but reimagined as fantasy beings with unique traits and requirements.

Some aquatic creatures can only be unlocked through exploration or research.

🐱 Manage Cats, Not Just Buildings

Your aquarium is run entirely by cats — staff and visitors alike.

•

Staff cats need fair pay and comfortable working conditions

•

Visitor cats come to see their favorite creatures, but also expect food, drinks, rest, leisure, and shopping

•

Ignore their needs, and strikes or reputation loss may follow

Keeping cats happy is just as important as keeping aquatic creatures healthy.

🔬 Research, Progress, and Optimize

Research new policies and perks to improve your aquarium’s efficiency and appeal.

•

Unlock new aquatic creatures and gameplay mechanics

•

Increase visitor capacity, tips, and inventory space

•

Improve staff effectiveness and aquarium operations

Multiple resources shape your strategy, including Coins, Materials, Research Points, and Hearts earned by satisfying visitors.

🏆 Compete for Reputation

Take part in regular aquarium contests and compete against rival aquariums. Earn reputation, climb the global rankings, and challenge the industry giant Star V. Co.

To truly complete your journey, you’ll need to discover and host a legendary creature — the ultimate test of your aquarium mastery.

🌦 A Living World

Weather conditions such as cloudy or rainy days affect atmosphere, visitors, and aquarium operations, introducing unique challenges that require thoughtful planning and adaptation.
