About This Game

You open your laptop at 9am. Three fish are already swimming. One of them planted something overnight — a small kelp sprout near the corner of the tank. You run a 25-minute focus session. By the time your break arrives, a rare visitor has appeared at the edge of the water, your plants have grown, and you've earned coins, hearts, and XP. By evening, you've completed your tasks — and your aquarium has grown with you.

AquaCorner is a transparent desktop aquarium idle game that runs as a living overlay on your screen. Not a separate window. Not a browser tab. It lives alongside everything else — always on, always thriving, and growing more vibrant the more you focus.

Your Fish Do the Work

Fish choose their own planting spots, sow their preferred species, and tend the foliage as it grows — all on their own. When plants reach full bloom, hit Harvest All and earn Leaf Points. Leaf Points raise vitality, higher vitality unlocks rarer fish, and rarer fish bring rarer plants. The loop runs itself.

Three habitat pillars — Kelp, Sandy, and Coral — unlock progressively as your ecosystem evolves, each requiring different fish and plant combinations to fill.

Built for the Way You Work

A built-in Pomodoro timer ties your focus sessions directly to the tank: complete a session and your fish celebrate the break — plants advance a stage, rare visitors appear, the ecosystem responds. The overlay runs silently beneath your apps. No required interaction. Glance, harvest when ready, return to work.

• Multi-monitor support — the tank spans all your screens

• Fish with Playful or Curious traits occasionally escape onto your desktop and wander between your apps

• Reach 80% vitality and trigger a Cascade Event: bioluminescent bloom, coin rain, rare visitor

• A message in a bottle greets you when you've been away

A Defined Journey

Five tank levels. Five unique ecosystem designs. Full bloom resets the tank at a harder difficulty and unlocks the next — up to a final fifth tank that marks a genuine ending. Track every fish and plant species discovered in your journal, and capture your full ecosystem stats with one-tap Share Card.

A living desktop that grows with you.
