Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0.29/day in the week to Aug 28 → 0/day in the week after.
Reviews, worldwide (the counter carries no country): 0.22/day in the week to Aug 4 → 0.57/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

ARC Aquarium delivers a peaceful idle simulation that revolves around creating and nurturing a thriving virtual aquarium. Instead of emphasizing fast-paced gameplay or demanding management systems, it focuses on slow, rewarding progression that allows players to enjoy building a colorful underwater habitat at their own pace. The game's straightforward design makes it approachable for newcomers while still offering enough long-term goals to keep fans of idle games engaged. Every session feels calm and inviting, making it an ideal title for players looking to unwind rather than chase high-pressure objectives. The game's strongest feature is its steadily expanding collection of aquatic life. Players can unlock dozens of different fish species, each with its own appearance, growth cycle, and contribution to the aquarium's economy. Feeding fish helps them gain experience and mature, creating a satisfying sense of progression as the once modest tank gradually transforms into a lively aquatic showcase. Watching the fish swim naturally throughout the environment adds personality to the aquarium, while the idle mechanics ensure that progress continues even when the game is closed. This balance between active participation and passive advancement makes returning to the game consistently rewarding without ever feeling like a chore. Customization is another major highlight, allowing players to shape the aquarium according to their own preferences. A wide variety of decorative items and multiple background themes provide numerous opportunities to create unique underwater displays. Decorations can be repositioned, resized, or replaced whenever inspiration strikes, encouraging experimentation instead of locking players into permanent decisions. The freedom to redesign the aquarium over time helps maintain long-term interest, as players can continually refresh the appearance of their aquatic world while unlocking additional decorative options through progression. The gameplay loop remains intentionally simple yet effective. Fish generate income that can be reinvested into purchasing new species, expanding the aquarium, or acquiring decorative upgrades. Regular maintenance tasks such as feeding fish and cleaning the tank introduce just enough interaction to keep players involved without disrupting the game's relaxing pace. Dirt accumulation encourages occasional check-ins, while cleaning rewards additional experience instead of feeling like a punishment. This design philosophy reinforces the title's casual nature, making every interaction feel meaningful while avoiding the frustration often associated with more demanding simulation games. Visually, ARC Aquarium succeeds through its bright art direction and pleasant animations rather than technical complexity. Fish move smoothly through the water, decorative objects help create depth, and subtle visual effects make the aquarium feel alive. Combined with its soothing soundtrack, the presentation creates an atmosphere that complements the idle gameplay exceptionally well. The game's modest system requirements also make it accessible to a broad audience, ensuring that players can leave it running in the background without placing significant demands on their hardware. Although the experience may lack the complexity and strategic depth found in larger aquarium management simulators, its simplicity is also one of its greatest strengths. The game never overwhelms players with unnecessary systems, instead choosing to provide a comfortable and relaxing progression loop built around collecting fish, decorating aquariums, and gradually expanding a thriving underwater environment. Players seeking intense management challenges may find it too light, but anyone looking for a cozy idle experience with satisfying customization and consistent progression will likely find plenty to enjoy. ARC Aquarium understands its audience well and delivers a charming simulation that remains enjoyable through its relaxing pace and welcoming design. Rating: 7/10
[h2]Eng[/h2] It's nice, but in my opinion, it's missing a few options, like the ability to change the aquarium background, to choose and add your own music (MP3 or from YouTube), and why is it impossible to use windowed mode at full resolution? These are, I think, relatively easy options to implement that would make the game much more user-friendly. For me, it's a 7/10 [h2]Fr[/h2] Sympa, mais il manque à mon avis quelques options comme changer le fond de son aquarium, la possibilité de choisir et ajouter ses propres musiques (MP3 ou en provenance de Youtube), et pourquoi n'est t'il pas possible de mettre le mode fenêtré en plein écran ? Ce sont là je pense, des options relativement faciles à mettre en place et qui rendraient le jeu tellement plus convivial. Pour moi ca sera un 7/10
Evde Balık Besleyip Su Faturası Ödemek İstemeyenlere için "Arka planda dursun, arada balıklara bakıp hayatı sorgulayayım" oyunu.🐟 Neleri Sevdim? Terapi Gibi: Müzikler o kadar dinlendirici ki oyunu oynarken uykum geldi, pozitif anlamda. Sanal Zorbalık: Gerçek akvaryumda cama vurunca balıkları ürkütmek serbest, cama tıklıyorum kaçışıyorlar, garip bir tatmini var. Gece/Gündüz: Işığı açıp kapatma detayı hoş olmuş, balıkların da uyku düzenine saygımız sonsuz. Çeşit Bol: Başlangıçtaki 20$ sermaye ile (bu ekonomide iyi para) bayağı çeşit balık ve dekor alabiliyorsunuz. Neler Gelişmeli? Sabır Testi: Balıkların büyümesi ve seviye atlaması biraz fazla "gerçekçi" Beklerken ben yaşlandım, balıklar hala ergenlikte. Çiftleşmelerini beklemek için bayağı bir mesai harcamak gerekiyor. Görsellik: Grafikler 2D ve tatlı ama insan şöyle jilet gibi 3D bir görsellikle balığın pulunu saymak istiyor. Belki ARC Aquarium 2'de görürüz?
[b] 一款在水族箱中模拟养鱼的挂机游戏,游戏的玩法是将鱼卵养至成鱼然后进行贩卖从而获取差价来购买更多的鱼类。游戏有三种可以收集的不同元素,不同的鱼种、不同的装饰、不同的背景和一个简单的等级系统,每次的升级都会解锁不同的新物品,获得经验的方式有通过鱼类本身的一段时间的挂机获得或是按住鼠标右键点击喂食。 虽说挂机和离线都会获得收益,但经过这几天的实测,增加了鱼卵的孵化时间,如果在鱼卵孵化后没有喂食即便第二天晚上还是长不到成鱼的,不过游戏中有85种的鱼类整体还是算得上需要控制时间来进行一波的收菜。 养不活鱼的可以养养赛博鱼。(*^_^*) [/b] 关注或加入群组 ,蒂蒂评测,答辩走开 https://store.steampowered.com/curator/43568093/
I did like this game but then it updated. While the update had some gameplay people had been asking for the fish models changed to clearly AI made art. I don't know how much other AI is used now and i morally can not support ai. the models were fine before so i have no clue why developer decided to ruin their work with AI. AI is trained on STOLEN work, AI is bad for the environment, AI data centers are taking massive amounts of drinking water and energy away from any community they are put by as well as causing heat and noise pollution. and it steals jobs from artists, programmers, and more. this creator took a cute sweet game and then used AI to ruin it. I can not recommended this game to any with morals. I hope the developer is ashamed. Especially since i waited on my review of the game when they said they where updating it. I waited on my review and left a community post comment about the AI hoping they would remove it so i didnt have to write this review. They tried to justify their actions by saying they are a small developer. I have played video games made by TWO people that are fully HUMAN MADE. Please spend your money on human made content not AI SLOP like this.
シンプルな2Dアクアリウムゲーム。 時間が経つと魚が成長。 水槽が汚れたら汚れた部分をクリックすればOK。 右クリックしたらエサが無限に出ます。 音楽もゆったりしているし 魚が泳ぐ姿が癒されるので 配信者さんは雑談にも向いていると思います。 Steamキュレーターを通じてゲームをいただきました。 ありがとうございますm(__)m
Ich kann dieses Spiel als Idle-Game und auch als Screensaver über Nacht sehr empfehlen; schon der Anblick der vielen bunten Korallen, die man da sammelt, macht Freude genug :) Und ist natürlich erheblich pflegeleichter, platzsparender und weniger risikoreich als ein echtes Aquarium ;) Ich habe mir dieses kleine Spiel am 13. Mai 2026 gekauft, als die Fische noch sehr simpel gezeichnet waren und wenig Unterschiede zwischen den Fisch-Rassen erkennbar waren; aber inzwischen haben zwei Updates ordentliche Verbesserungen gebracht, nicht nur in der Grafik, sondern jetzt zuletzt einen schnelleren Stufenaufstieg und tägliche Belohnungen. Das bringt was. Mit vielen Fischen - sprich: mit vielen Animationen - ruckelt das Spiel allerdings schon leicht; was mir nicht wirklich was ausmacht, aber vielleicht wird sich daran in Zukunft ja noch etwas ändern.
Recommended I already have more than 5 hours in this game, and honestly, I couldn’t stop playing. It’s a relaxing aquarium farming game where you hatch fish, raise them, expand your collection, and earn money over time. The progression feels rewarding, and there’s always something to do, whether it’s unlocking new species or improving your aquarium. The game is simple to learn but surprisingly addictive. If you enjoy idle, farming, or aquarium management games, this is definitely worth trying. Great job by the developers!
I've been enjoying this game a lot more than I expected. The atmosphere is calm and relaxing, and it's surprisingly satisfying to watch your aquarium grow over time. The visuals are clean, the fish animations look great, and the overall presentation feels polished. It's the kind of game that's easy to leave running while you work or just want something peaceful on a second monitor. Looking forward to seeing how it evolves with future updates. Definitely worth checking out if you enjoy cozy and relaxing games.
