Chillquarium Is a Cosy and Relaxing Idle Game Full of Fish, Out in Early Access

After launching on PC in September 2023, Chillquarium is coming to mobile. Developed by indie solo developer Ben Reber, the game is getting published by Swedish publisher Snapbreak Games on mobile. It gets a full launch on August 5th, 2026.

But, Chillquarium is now out in Early Access on Android

The game sticks to a simple loop. You pick up fish, let them grow in real time, and eventually sell them for profit. Or you can keep them around as a steady source of income through ticket sales.

It’s not much active management and more about checking in occasionally. You watch progress unfold. Your basic starter tank can slowly turn into a heavily customised aquarium filled with rare exotic species and even ultra-rare colour variants.

There’s a wide pool of fish to collect, along with decorations and upgrades. The presentation is full of calm visuals and ambient sound. Take a look at Chillquarium below and see for yourself.

You can unlock fish through booster packs, and there’s a feeding frenzy mechanic that helps them grow faster. It offers a gacha-style chase for completing sets or finding golden and legendary variants. Altogether, the game includes 156 unique fish.

There’s also a real-time day-night cycle that subtly changes the atmosphere of the aquarium. I’d say that Chillquarium is a truly low-effort, low-stress title that you can try out if you’re bored or whatever. It’s available on the Google Play Store for free.

Apparently, Ben Reber developed Chillquarium entirely on his own over nearly four years, handling everything from programming to art and music. It started as a passion project, and despite having very little marketing behind it, the game managed to break out on Steam.
