Fishly: Desktop Aquarium

Fishly sits in the corner of your screen in a transparent window. While you work, study or stream, your fish swim around, earn gold, get hungry, lay eggs and slowly dirty the glass. Drop by for a few seconds: feed them, wipe the glass, hatch a new fry, then get back to work.


Fish never die and nothing punishes you for being busy – a hungry, dirty tank just earns a little less.

• 10 species, from Neon Tetras to Discus
  
• Real genetics: 6 colours (Albino, Melanistic, Golden, Ghost, Rainbow…), 5 patterns and 3 fin types, each carried as two alleles
  
• A family tree for every fish, and a 60-entry collection album
  
• Share a fish with a friend as a code – they get an egg with the same genes

• Tank levels, themes, daily and weekly quests, ~45 achievements and titles
  
• A second tank, and prestige with pearl upgrades when you want a fresh start
  
• Seasonal events and a rare rainbow visitor to catch

• Desktop mode – a transparent window, clicks pass through to your desktop
  
• Wallpaper mode – the aquarium moves behind your desktop icons and your own wallpaper becomes the water
  
• Full-screen mode – for when you just want to watch
  
• Real-time day and night: your fish sleep when it's night where you are
  
• Offline progress: your tank keeps earning for up to 72 hours while the game is closed
  
• Light on your PC: frame limits, lower FPS when other windows cover it, battery saving
