About This Game

Turn an empty tank into a living aquarium of your own. Buy fish as eggs, hatch and raise them in real time, then sell grown fish for profit. Breed new eggs, complete a 125-species catalog, and shape a calm aquarium that rewards both quick check-ins and long-term care.

🐠 Hatch, Raise, Sell

• Every purchased fish arrives as an egg—hatch it and watch it grow
  
• Feed fish to earn EXP and speed up their visible growth
  
• Sell grown fish for profit, or lock favorites so they can never be sold by accident
  
• Discover 125 freshwater and saltwater species, each with its own appearance, value, and unlock level

🥚 Breed and Complete Your Collection

• Pair an adult male and female of the same species to produce new eggs
  
• Raise your own fish instead of buying every new resident
  
• Your permanent catalog records every species you discover while keeping undiscovered entries hidden

🪸 Design a Tank That Pays Back

• Unlock 86 decorations and arrange, resize, layer, or sell them freely
  
• Every placed decoration generates passive gold while the game is open
  
• Choose from 9 backgrounds and customize the interface color and transparency

📈 Progress That Respects Your Time

• Fish and eggs continue progressing while you are away, for up to 24 hours
  
• Level up to unlock new fish, decorations, backgrounds, and more tank capacity

🎮 A Calm Aquarium to Keep Beside You
