The world inside your fish tank is a universe in miniature. Place it anywhere on your screen to transform your desktop from a place of work and study into a serene harbor for your mind. It's more than just a visual treat; it's your personal retreat. Zoom in and out seamlessly to admire your fish up close or to focus on your work. When the pressure of the day gets to you, why not take a short break to watch your fish glide peacefully and let your mind relax?

Caught up in the grind of work or study? Feeling the pressure? We all need a quiet space to clear our heads, but there's no time to get away. That's where your aquarium comes in. A glance is all it takes to find your peace in the gentle sway of your digital fish... It's an instant escape, right on your desktop. Simply set it and forget it. Your fish will grow, and beautiful moments will unfold while you're away.

From the Clown Knifefish to the Discus, hundreds of exotic species are waiting to be discovered! Buy Fish Packs to draw and unlock over a hundred freshwater and saltwater specimens. Complete tasks to earn coins, decorations, and resources to make your fish-keeping journey even more fun and rewarding. With such a rich variety of species, your aquarium will become a visual masterpiece. And who knows? If you're lucky, you might just hatch a mythical, ultra-rare fish!~
1 fish, 5 fish, 10 fish, 200... watch your aquarium flourish! Complete management tasks to earn a wealth of coins, decorations, and resources to make your fish-keeping journey easier and more rewarding. Think feeding is too much of a hassle? No worries! Use an Auto-Feeder Ticket to set your hands free. You've earned it!

With nearly a hundred decorations and six distinct tank styles to explore, you are the artist. Buy Decoration Packs to unlock rare items and create a lush, captivating environment. Will your fish swim peacefully under blooming cherry blossoms, or cower before the might of a black dragon? The choice is yours. These decorations don't just look good—they boost your efficiency, increasing feeding XP and growth rates! Watch as your corner of the desktop blossoms into a world of your own making.

A good tank manager knows the secret to success: selling mature fish at the right time to fund upgrades for your tank and decorations. This is the key to a smooth and satisfying idle experience. Should you fill your tank to the brim with fish first, or focus on creating a stunningly beautiful environment? Perhaps this is the eternal dilemma of the fish-keeping master.
Wait, shhh... Has the boss left the room? Okay, quick—time to check on your fish!
Idlequarium for PC starts at €1.71 at Difmark Digital Keys, a Steam key, which is 71% under the €5.89 it costs on the official store.
That €1.71 already includes the Gocdkeys coupon, so apply it at checkout or the store will show you a higher price.
Supply is thin — 6 offers from 5 stores — and thin supply keeps prices steady rather than falling.
That puts it 38% under its average of €2.78 since 2025, so today is a better entry point than most days of its life.
That €1.71 key is at one of its best prices.
Worked out from 660 daily records of the Steam Key for Idlequarium across 5 stores. See the full price history.
The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.
5 of the 6 offers work on US — the Global ones plus the ones issued for your own region.
