Aquarium Bubble

A small transparent underwater window for the corner of your screen — fish drift by, you feed them, and rare visitors appear.

Open Aquarium
Try it live
Tap the water to drop food — the nearest fish chases it. Watch for shimmering visitors.
What it does
  • A window, not an app
    A small transparent underwater corner — light rays, drifting motes, swaying seaweed — that lives quietly at the edge of your screen.
  • Feed them
    Tap the water and a food pellet sinks — the nearest fish turns, chases it down and gulps it with a happy munch.
  • Discover rare fish
    Undiscovered species occasionally swim through with a shimmer — tap one before it leaves and it joins your collection. Feeding attracts rarer visitors.
  • Make it yours
    Five waters — ocean, lagoon, sunset, abyss, kelp — plus a bubble wand and a collection panel to choose which fish live in your tank.
  • Private by default
    No accounts, no tracking — your tank and collection stay on your device.
