60 of 113 · most liked firstTL;DR: If you seek a productivity companion with good tunes and white noise options, you can pick Fantasy Aquarium, but you should be aware that it has no active gameplay options at all. The "productivity companion" part of this game is great, with its tunes and white-noise profiles you can toggle on and off to create a pleasant working environment. Besides the productivity-related features, the game offers almost no gameplay options, and I lost my interest in the game in less than 10 minutes…
negative · reviewer's own thumbsView post →Fantasy Aquarium is a relaxing aquarium game. Collect rare fish and themed decorations from capsule machines and card packs! Demo available in Steam Next Fest.
unlabelledView post →As far as I can tell this is a very slow paced idle game you are supposed to enjoy passively. Loving the lowfi aesthetic and customization. Game is functional and pretty to look at. Preforms well on deck. Just dont expect too much from this game. Will update review as I progress a bit further
positive · reviewer's own thumbsView post →It just never ends. I'm an achievement gremlin, 100% in this game requires you to purchase and raise every single fish type, all rarities, including variants. Some fish can take literally a week to grow, and your space to "buy/sell" in mass to get the entries in your journal is very limited. You can't just sell off ALL your fish, because you need an income, but there's a fish journal with about 300 individual entries to complete... Poorly balanced, no real interactivity at all, rarity system…
negative · reviewer's own thumbsView post →game is not worth it. got it on sale, even then I still feel cheated. the game has poor translation, like really rough. the tutorial doesn't work, which are supposed to just be images by the way, and somehow I had trouble opening them, and had to use a controller to somehow access them there's only 2 resolution, 1080, and 720, absolutely nothing else. the default pixelated font are hard to read, and i had to read a review to find out you can change the font. the fish "Binder" which shows…
negative · reviewer's own thumbsView post →this isnt really a game. you dont feed the fish or clean the tank you just buy fish and then wait for them to earn xp so can buy more fish. literally nothing but waiting. why this is 7$ i have no idea
negative · reviewer's own thumbsView post →As a guy pretty into screensaver and idler games as well as tedious grindy fishing mechanics occasionally on the odd while this is probably one of the least interactive games I've come across, and I don't recommend it at all. First of all, to start off with the bad and explain how it works in Fantasy Aquarium, there isn't any particular gameplay loop to this game nor is there anything to do with the fish you obtain, or any mechanics behind obtaining anything. You'll initially start off with a…
negative · reviewer's own thumbsView post →So, this game is BEAUTIFUL, I put in the time because I love to see the pixel art fish bounce on the backgrounds. Though there's still I have yet to unlock, I really hope the dev can bring in more tanks/types of fish because I don't want the collectathon to end. However, this is an IDLER idler: you can't do much to speed it up, but that makes it ideal for people who like Spirit City and just want something to plug away at between hours of work. I like to have it open and sell fish/resupply my…
positive · reviewer's own thumbsView post →Fantasy Aquarium is cute idler game where you make your own aquarium. The game is meant to be very slow for idling in background. Pros(+): + Cozy slow game + 10 chill music track you can choose from + Various white noises like clock ticking, rain sound, Sea sound etc. + Tons of fish variety. + Game still progress even when you close the game. Cons(-): - some UI need works. - Font kinda hard to read. All in all, the cheap price is really worth for background game.
positive · reviewer's own thumbsView post →Honestly, I definitely wouldn't have recommended this game to others when I first started this game. I was mostly grinding because I liked the gacha, art, and of course the achievements. The reason why I wouldn't have recommended it is because it wasn't very user friendly. Such as only having 2 resolutions, it's hard to tell which fishes are shiny or not, sometimes the UI is bugged and have to click multiple times or clicking a specific spot to show up and etc. But not gonna lie, it does seem…
positive · reviewer's own thumbsView post →It is way too idle. I want the 100% but its just open it, buy-sell close it.
negative · reviewer's own thumbsView post →First : it is not a game but a desktop saver; there is literally nothing to do Second: the game did no longer start after 39 hours which is a known issue . The devs "solution" did also not work. So don`t buy this crap After restarting + another 150 hours of "game" it crashed again and I lost every progress. DO NOT BUY THIS PIECE OF ... !
negative · reviewer's own thumbsView post →It is very apparent this game was made with no love, or at the very least, interest in developing it was abandoned halfway through the project. It is a major time sink - some fish take an entire week to grow. Tutorial pop ups are repeated and constant, with no way to shut them off. The UI uses a pixel font which is barely readable. Fish varieties/rarities are confusing. The "investment system" to get rarer fish is not explained at all, and requires 12 open slots in an aquarium to utilize.…
negative · reviewer's own thumbsView post →Kinda nice, not an active gameplay, just join once a day buy or sell a fish and leave until tomorrow. this is not special, there is a lot of game like this that i won't even launch to play but this one have a vibe that i like.
positive · reviewer's own thumbsView post →Boring. Can't even hook you in with a good start. Bought as part of a bundle so I don't think I even paid a dollar for it. But it wasn't even worth it.
negative · reviewer's own thumbsView post →Nothing to do. Boring even for a idle game. Refunded.
negative · reviewer's own thumbsView post →Seriously lacking in polish. Needs work. The localization needs work. The UI needs work. The menu needs work. 1. Once you open the menu, there's no way to close it. Just exit the game and restart. ESC does nothing, and there's no close button for the menu itself. 2. The reset game option is labeled as restart, not reset. 3. The tutorial isn't obvious, at least to me; it shows some images and says you can revisit the tutorial in the menu (I thought I'd missed the tutorial. Nope, that's it).…
negative · reviewer's own thumbsView post →All the mermaids make me so happy the devs KNOW WHAT WE WANT! WE WANT MERMAIDS! WE WANT SHELLCATGIRL!!! I'm obsessed with this game
positive · reviewer's own thumbsView post →Possibly the most important thing you have to know is: The money accumulates even when you close the game. It is very slow. It's probably balanced roughly so you can buy one thing per IRL day, and progress slowly like that. It's great as a relaxing wallpaper or work companion, and also fun to collect / open lootboxes without predatory mechanics. The fish are very cute, and the large variety and different stats make them interesting. Playing on 4K is easy by using alt and enter to full…
positive · reviewer's own thumbsView post →After 650 hours of Chillquarium, I can say that it is an interesting version of it. I am a simple man: I like fish games and I like idle games. I like idle fish games. So I like this one. I obviously haven't seen much, and the game is barely released (yesterday), so I can't take any 100% assumptions of it. But it looks interesting: the anime aquarist girl, the background music, and the whole beautifully pixelated sprites. Yeah, I'ma keep playing it till I can't no more, no more.
positive · reviewer's own thumbsView post →things that should be added for a positive review: - have the game remember whenever you change the volume of the music, sound effects or the master volume - game should have the option to either run on windowed or fullscreen mode, also remember this setting whenever it opens - there should be a way to see how much money you earn per second/minute/hour/day if this is changed i'll be able to give it positive review
negative · reviewer's own thumbsView post →Idle fish game, this is the game for you if you're just a chill guy
positive · reviewer's own thumbsView post →Open game, sell fish, buy new fish, close game. There is absolutely nothing else to do unless you really want generic lofi, but there's youtube channels that already do this for free. Even for an idle game, there's just nothing to do. No decorating the tank, no feeding the fish, just buying and selling fish. There are better idle games about fishtanks.
negative · reviewer's own thumbsView post →very unintuitive mechanics and completely unexplained features; buying the luck tickets only works if you have twelve open spots in a given aquarium, because of the chance that you get 12 fish in one draw (i thought this was bugged/broken but it was just unexplained and i only figured it out when i put more time into the game). really sucks that theres no option to min-max AKA invest any actual "play" time, you just have to wait because you cant feed your fish to speed up their growth (unlike…

positive · reviewer's own thumbsView post →Nice chill game, you can even run it in background. Requires patience and time to get the rarer fishes and their growth varies from few minutes to multiple days. Edit 1: It seems the fish grow and gold increases when you close the game as well. Edit 2: There's a limit to gold received when offline (1 000 000), requiring to log in on regular basis and (considering the chances and cost) with little to no results.
positive · reviewer's own thumbsView post →I am enjoying this game a lot, love the music, I can just let it all play like hours and hours and I wont get tired of it, and its fun seeing the fishes swim around as I do my own business >///< ABSOLUTELY love this game!
positive · reviewer's own thumbsView post →Really pleasant to have on in the background. Gorgeous pixel art makes it beautiful to look at. Its very simple compared to other idle games but that's part of its charm. Would love achievements to be added to the game ~
positive · reviewer's own thumbsView post →After everything that happened with the game, the gambling, the fishies, and everything around it, I’ve been wondering about something. Was all of that just a part of my character development, or am I still in the middle of that arc? Like, is that chapter actually finished, or is there still more to it? ACHJA I FINALLY FINISHED IT AHHHHHHHHHHHHHHHHHHHH
positive · reviewer's own thumbsView post →Menus are counter-intuitive. Not for me.
negative · reviewer's own thumbsView post →please add the option to also save the game without exiting, like save and resume, save and continue. something of the like it would be very much appreciated :) this game is Awesome. Beautiful, and good for blood pressure. thank you 9/28/25 addition; it's a good game on the side. you'll set things up and then check back later. the slow daily progress is nice if you know what you're getting into.
positive · reviewer's own thumbsView post →Got it on sale, and its not worth it. the tutorial doesn't work and the font is garbage and the English leaves a lot to be desired. The lo-fi music is Eh. Normally I turn off the music anyways however this game doesn't remember what your settings were from one play to another. I was looking for a cool tank game, this isn't it. can't feed the fish, can't clean the tank, can't even interact with the fish. A fishing disappointment
negative · reviewer's own thumbsView post →Cute game with nice visuals and great sound design. Good to have on a second monitor type game.
positive · reviewer's own thumbsView post →Nice to run in the background. Chill music and an array of ASMR sound effects to help relax and focus when writing for example. I like aquariums and fish too so I look forward to unlocking more of them. The only thing I am missing is the option to customize and/or decorate the aquariums and the option to have it cycle through all songs (or those you select) rather than looping one song you selected over and over.
positive · reviewer's own thumbsView post →Relaxing idle fish tank. You collect fish, unlock more fish tanks, play gacha for fish/decorations. It's a pretty game with relaxing music. The money you earn accumulates when the game is closed as well which is great. You log out and can log back in the next day with more money. There isn't much to do as its an idle game, its a cozy game that is pretty chill. The pixel art is also beautiful.
positive · reviewer's own thumbsView post →I love pixel fish
positive · reviewer's own thumbsView post →Not very well translated, nor does it have a great explanation on what to do. It feels like the dev abandoned this project. Could've been a great idler game had it not been so damn slow to progress, but it's a good idler, doesn't feel incremental, well maybe because it's not meant to be?
positive · reviewer's own thumbsView post →I like this game because there is nothing much to do. The art and music is very relaxing. Update: The achievement is very hard to get 100% avoid this game if you wanna get perfect achievement. I gonna give up on that.
positive · reviewer's own thumbsView post →i wish i didn't try idling this so i could get my money back.
negative · reviewer's own thumbsView post →An odd little idle/gacha combo that I currently have mixed feelings about, because the tutorial wasn't well done and the wait times for idle earnings from your starter fish are a bit long. (Nowhere does the game tell you that the fish need to earn XP before they can earn money, you just find out the hard way after blowing your starter dollars.) However, since I got the game on discount and still enjoy listening to the music while doing other things - plus the graphics are simple and cute - I'll…
positive · reviewer's own thumbsView post →i would only recommend buying this game if it's on sale. it's a cute fishy idle, but there's not much further than that. the art and music are nice.
positive · reviewer's own thumbsView post →LOVE LOVE LOVEEE fishhhhhh fish fish fishy fish bloblobloblobloblob bwbwbwbwbwbwbw I love fish tism fish game yes play now if u has fish tisms too -- Ok proper review the arts so silly I love the pixel style i could just eat it, Its a bit hard to start at first cause your fish dont earn ♥♥♥♥♥♥♥♥ but after a few hours and gambling on the machines you should be set to just have a nice fish tank :33 I mainly leave this running in the bg while im crafting so i can look over at my lil fish while…
positive · reviewer's own thumbsView post →I got this since there's a sale. I even booted up Cheat Engine simply to speed up the game to 10x. It is... so slow. Sure, idle games with slow starts can be par for the course. But this... wow. Four hours of letting it run in the back, I managed to get the second tier tickets for new fishes ONCE. Even with the four fishes from that second tier, things didn't change. And you do nothing but gacha the fishes, wait for them to reach max EXP, which is when they start making money, then you sell…
negative · reviewer's own thumbsView post →it's kinda decent for an idle game, its mesmerizing seeing your fishes grow on/off screen, I tend to let it run my background while I'm doing other stuff away from my PC, its convenient. Music on the other hand, a 5/10 imo, the soundtracks sound very adventuresque, I do see the vision that their trying to go with, but for my fish keeping simulator game there's something missing to it.. maybe its just me i guess. Though I like it very much!
positive · reviewer's own thumbsView post →A great idle fishing collector game. The music is a nice chill vibe, and I love the adorable pixel artwork. There are tons of fish to collect and it is a lot of fun mixing and matching the fish to the different tanks. I really love how the tanks look after you get decorations since each tank has its own unique charm to it. Fantasy Aquarium is definitely a slow game, and it is great how you can just log in each day to watch the fish bounce across the screen. Also there is slot gamba which is an…
positive · reviewer's own thumbsView post →This game is quite alright. The art style, in case it wasn't obvious, is really pleasant to look at. The font can be a little difficult to read, but luckily there is an option for a more easily readable font. The background music is nice and relaxing and there even is an easy option to change the current song, which is nice. There appear to be quite a lot of fish, so no complaints there either. The UI however, definitely shows that the creators are not English speakers and did a pretty bad…
positive · reviewer's own thumbsView post →Not as content-rich as I thought in the first place for a full game version, especially when I noticed both the girl and fish are not interactive. Better waiting for future updates. P.S. Devs may have overestimated the minimum system requirement for this game. I can actually run this game in 60 FPS on an aged 64-bit Windows 7 OS laptop w/o any problem.
positive · reviewer's own thumbsView post →Very good white noise player.
positive · reviewer's own thumbsView post →Fantasy Aquarium features a very consistent system of visual rendering. Through meticulous observation, I discovered that when a fish moves its tail, it travels from one side of the tank to the other. If it stops moving its tail, it remains stationary in the water. Furthermore, if you keep your eyes open, you can see the fish swimming. However, if you close your eyes, the fish become completely invisible, though you can still hear the water bubbles if your speakers are currently receiving…
positive · reviewer's own thumbsView post →I feel like the game could have updates to improve what players are complaining about, but alas, it is an okay game. The anime girl is cute, the fish are cute. That is all.
positive · reviewer's own thumbsView post →I just noticed the game doesn't need to be running to collect money! Sorry for my previous bad review
positive · reviewer's own thumbsView post →What is this? got stuck at the beginning, no money no nothing, is this even a game?
negative · reviewer's own thumbsView post →I love leaving this game on my TV. Music and SFX are good for studying or just idle. The fishes are sooo cute specially the stingray! While there are some things hard to understand such as the betting system, you can get by without using that feature. I hope one day it'll have supports button/controller!
positive · reviewer's own thumbsView post →The gameplay such as it is, is just adding fish to the aquarium and gaining passive income. The white noise system, however; is very nice, and that is the reason I would recommend this. Pick it up on sale if you like gentle music and white noise or just like the idea of watching pixelated fish swim around.
positive · reviewer's own thumbsView post →so cute, fish....
positive · reviewer's own thumbsView post →Not recommended if you're an achievement completionist. The fish qualities are not clearly labeled or defined. They also use pixel font on their in-game fish book which i barely readable. I'm also still wondering if "obtain all colorful ordinary fish" means getting any quality variant fish with glowing features or if it's green/blue/gold quality variant fish. I can't match the number in the fish book to the achievement.
negative · reviewer's own thumbsView post →pretty slow start but an otherwise nice little aquarium game, filling out all the decorations is a really satisfying unique feature showing the scene develop as you progress
positive · reviewer's own thumbsView post →Simple, cute pixel art idler. I like the variety in fish, it's straightforward, and the art is very good. I wish it had more music tracks or perhaps a timer feature so I could use it more to study. But overall, not bad! My cat likes looking at the fish too.
positive · reviewer's own thumbsView post →i haven't touched this game for months at a time and actually forget i have it still installed, but its a good idle game nonetheless since it does wat its supposed to do.
