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): 1.57/day in the week to Aug 23 → 2.86/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 24 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,404 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.

you get to feel like you are rich and have fish friends while chillin
Chillquarium is just what the name entails - a chill aquarium game about collecting fish and then using the money to collect more fish. It's simple, charming and endearing - it's as easy or as hard as you choose it to be, largely, and it can take just a few hours of sessions spread over a long time, or like I chose to make it, a dense block of active time consecutively. The game really does move at your own pace, which is good for a game trying to be a chill experience. If I have to levy some criticism against Chillquarium, though, I will say that the rewards for actively engaging in the game far outstrip the passive income generation - buying, growing and selling just a few packs of fish is more money than you're likely to generate passively, meaning that if you choose to put the idle in this idle game, you'll be waiting a lot of real-life time. Additonaly, I found that the money requirements for extra tanks felt a little limiting, and I was a touch disappointed in the total amount of tank space. There's still enough to store one of every variant of every fish, but I would've liked a little more headroom so I could organise things a little differently than I've had to, but those are very minor complaints. Lastly, I think rainbows and Alt painteds can feel a little frustrating to obtain due to both rarity and randomness - though I think it's fantastic that the pity system for rainbows seems to always try to grant an unobtained rainbow fish, I do wish that also extended to alt colour painteds. Overall, though, none of those types are needed to complete the game - they exist only for the truly dedicated, so perhaps it's fitting that they're much more time-consuming to obtain. Chillquarium is a game I've enjoyed playing, such as it is, and it's a game I will enjoy continuing to play. My review is done, but rather uncharacteristically for me, my actual playtime continues - after all, I haven't gotten all the rainbow fish yet, and I don't intend to stop while I'm so close to my living dex completion. At time of review, Chillquarium took about 138 hours of active play, and is certainly worth the money for the relaxation and collecting aspects. If you're reading this, any remaining time is how long it took, or is taking, to get the remainder of the rainbows. I'll catch them all yet, no matter how long it takes!
