About Just Fish: Idle Aquarium
"Buy fish. Feed fish. Watch fish grow.
Sell fish - if you want more.
Relax. Repeat. And feel relief.
While you leave, they live."
“Just Fish” is a relaxing idle aquarium for quiet moments.
Get fish from themed collection packs and watch them grow in real time.
Feed to help them grow faster.
Sell adult fish to buy more fry and discover rarer species - or keep them for steady income.
Build your oasis: unlock and place decorations, and enjoy fish interacting with them.
Use the game as a second-monitor screensaver, or pin a mini view in a corner for a small piece of calm while you work.
Your world keeps earning even while you’re away.
