About the 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
  • Claim rewards throughout a 30-day daily login cycle
  • Complete 24 in-game achievements and track every unlocked milestone

🎮 A Calm Aquarium to Keep Beside You

  • Play actively for a few minutes or leave the aquarium running while you work or relax
  • Clean the tank for bonus EXP and care for sick fish; neglected fish can be cured and never die
  • Capture clean, UI-free aquarium screenshots with the ARC Aquarium logo
  • Available in 23 languages
