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 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.

Reviews
Very nice chill game. Fishes are pretty, background music is cute enough and the hunt for rainbow fishes is exactly as it should be. One of the rarest pulls you got so collecting all of them is actually an achievement! Worth getting especially when it's on sale.
I like this game; chill as described, a good game to waste a few minutes every once in a while for an idle, incremental, though for me, once the I get the achievements, probably not much replayability after.

very chill very fish
I like this game for what it markets itself to be: a relaxing idle game where you collect fish. There are enough steam achievements and unlockables that keep me coming back. After I reach all the achievements and unlock everything I don't know if I will really touch this game again. But it takes a very long time time to unlock everything (I havent yet) so I think the price is worth it. I see its also comign out on IOS soon which I am looking forward to putting it on my ipad and falling asleep to it. The music is so relaxing. I do wish there were more variation in music though.

水槽を眺めながら、魚を育てて、増やして、売って、また新しい魚を迎えて……。 ゲームをガッツリやる気力はないけど、何か起動しておきたい。 そんなときにちょうどいいゲームです。
终于拿完全成就了来给评价,彩虹全图鉴太难了,我放弃了。 一般般只能说是中评,毕竟是收集马拉松类型的游戏,游戏性很差的拆包模拟器,对全图鉴玩家并不友好。 玩这个游戏你可能会遇到的 1.死活刷不出来的彩虹鱼,不仅便宜还丑,爆率更是低的要命。 2.有些鱼是有不同的彩色的,不仔细看图鉴根本不知道,而且可能会在你就差一个颜色时死活刷不出来,然后疯狂蹦其他你有的颜色。 3.商店里面灯光、鹅卵石、装饰物没有任何增益。装饰物一个缸最多放仨,优先级是最后买的在最前面,还改不了。 4.有黄金通行证之后瞎买最贵的,或者说目前最贵的黄金鱼苗包容易一朝回到解放前。
太太太逆天了,升级一次以后投喂加10点进度然后传说要50多万?不说还没养完的高级鱼,就是普通鱼和稀有鱼的养成时间和价值差异都很难绷,稀有鱼还没普通鱼性价比高
就是正常的增量游戏消磨时间啊 爆率不合理,但毕竟消磨时间了就无所谓了 但对不起这个价格
