Chillquarium

Chillquarium is a casual idle game where players build their dream aquarium from scratch. You'll stock different fish fry and carefully feed them various foods, watching them grow into different fish species and their variants. Players can also unlock higher-level, rarer fish by opening upgrade packs. Once your fish reach a certain stage of growth, you can sell them to earn money to buy more upgrade packs and upgrade your aquarium, such as adding various interesting decorations to match your aesthetic. The game supports an offline idle system; even when you leave the game, your aquarium will continue to earn coins for you, making the game even more enjoyable.

Gameplay of Chillquarium:

Chillquarium is an idle fishkeeping game, you can collect fish by buying packs, the first being the Freshwater Friends Pack.Chillquarium only auto saves every 60 seconds, so make sure to select "Save and Quit" from the pause menu to avoid losing progress.

Growing fish: Fish grow naturally over time (1XP per second) even while the game is not running, but this process can be sped up by right clicking to feed your fish, which will give them 5XP (food efficiency can be increased with upgrades). Each fish card in the collection screen shows how long it takes to grow up naturally. Adult fish will chase food, but they do not consume it. Fish can also be given names.You can increase your tank limit and buy new tanks to hold more fish by purchasing upgrades.To prevent a fish from being sold, you can lock it by clicking the lock button on the fish's profile.

Making money: Fish can be sold for money, which can be used to buy more fish packs. Adult fish are much more valuable than baby fish, so you should wait until your fish mature to sell them. High rarity and colored (painted, golden, rainbow) fish produce much more money than their uncolored versions.Fish can also be kept to earn money; each fish produces a certain amount of money per day while in the tank, and rarer fish typically earn more per day.An easy way to sell fish quickly is by using the "s" hotkey when selecting a fish, or by selecting the "sell all unlocked fish" in the bottom right of the tank menu. This will only sell unlocked fish that are displayed under your current filter settings, so

Useful Tips of Chillquarium:

Don’t Sell Golden Fish (No Matter How Much They’re Worth): If you encounter a gold or rainbow fish, don’t sell them! These are the equivalent of shiny Pokemon in this game, having just above a 1 out of 1000 chance of spawning from your fish packs when you summon them into existence after buying them from the shop. Once you’ve opened about 2,000 packs, you’ll have a guaranteed gold or rainbow fish come into your tank, so keep a lookout for them. I was lucky enough to get one quite early on, so my passive income is going to be just a little bit better from here on out.To prevent yourself from accidentally selling your precious golden or rainbow-colored variations of fish, try pressing the Lock button on your fish by either clicking it in the tank and finding the Lock button or going to your fish list and clicking the Lock button there. If a fish is locked, you can’t sell it, even if you accidentally click the sell button. Golden fish may be worth a ton of money, but the passive income they earn you is much more valuable.

Sell Every Other Fish Possible As Soon As Possible: The point of the game is to sell fish and buy fish if you want to progress in the game as quickly as you can. While Chillquarium is definitely not the kind of game to be rushing through at breakneck speed, the beginning can be pretty slow. To help yourself reach more fish variations as soon as you can, sell fish as soon as they reach maturity. While they may be making you a bit of passive income, any fish from freshwater don’t make that much money, even when you have a tank full of them.The goal at the beginning of the game is to make money as quickly as you can in order to get yourself a Saltwater Tank. Once you have enough spare cash, you can buy Saltwater fish in the Reef Fellas, Marine Dwellers, and Giants categories. Until you get to that point, though, you’ll have to stick to Rivers and Ponds, as well as your Freshwater Friends category. Once you start owning any kind of Saltwater friend, you’ll begin having fish that are worth way more than the Freshwater variants, earning you more money and paving the way for expensive purchases like cosmetics to decorate your tank.

Use Alt + Tab to Auto Feed Fish: While fish grow on their own by earning 1 EXP every second, you can feed your fish to gain 5 EXP each time they eat. By holding down the right click, you can feed your fish continuously to have them grow into adults as fast as they can so that you can sell them. However, if you want to make this idle game even more idle than it was before, try holding right-click while Alt Tabbing out of the window. If you do so successfully, the right click will stay right-clicking in-game even though your mouse is not there anymore, continuously feeding your fish in the spot where you left it. Doing this in a lower corner can help after gathering all your fish in one place, helping grow the entire tank at the same time. It’s not exactly a game mechanic, more like a glitch, but you can use it either way to supplement your fish-feeding frenzy needs.

Before You Leave, Fill Your Tank: If you’ll leave the idle game running for a bit as a screensaver on your computer, try not to leave an empty tank when you go. While selling fish is the name of the game here, fish earn passive income when they are adults. So, if you’re just about done playing and are tempted to sell your tank for a quick last-dash buck, consider leaving your most profitable fish passively swimming around so that your hours of idle screen saving are used efficiently. If you want to create a little calm ambiance for yourself, turning on the setting Sparse Music can turn the constant soft guitar into an occasional (unedited recording of) soft acoustic guitar that plays every couple of minutes to help interrupt the soothing drone of the aquarium tank.

Player Comments of Chillquarium:

So far it delivers as promised and is exactly what I've been looking for. It's a chill clicker/idle game with lots of fish to collect and some stuff to unlock. Best yet, all it asks is a small purchase to unlock all bonuses, although everything is available for free. It's refreshing to see a mobile game not try to kill you with a thousand IAPs.

This game is very relaxing! its so fun to unlock new fish and grow you tanks and income. Also as someone who tries not to be glued to my phone for a game, earning double income offline encourages me to put the game down more often than playing so that I can update everything sooner. I love this simple little game, please keep this game going!

I love this game a lot so far its very nice to play at night bcs of the low light mode but I think a really interesting idea would be is adding weight variations so you could have like a super huge fish or a super small one idk how you would implement it but it'd be rlly cool for a future update! love the game.

Great game, just like the pc version. It does have a bug where if a new undiscovered fish grows up while you are afk, there isn't a pop-up telling you about it when you come back. Also, the ui is a bit finicky. looking forward to more updates.

I like the game, its fun for sure. I open it atleast 3 times a day. I just wish you could decorate more with plants etc. make it look like a lively tank. But there arent really many options for tank decor. There are pebble colours and light colours for the tank. One thing i dont like tho, is when you feed the baby fish, the adults also go over to where your finger is, even tho they dont eat anything. Its just a little annoying when I want to watch the little ones. But i totally recommend it.

Final Verdict:

Chillquarium offers a soothing idle experience where players buy, raise, and sell a diverse array of fish in real time to build the ultimate aquarium. The game’s charm lies in its blend of casual gameplay with strategic collection and customization elements. Players start with a basic tank and gradually unlock rare and ultra-rare color variants among 156 unique fish species, enhancing both their collection and earning potential.
