Chillquarium

Chillquarium is a laid-back idle game where you grow a tiny school of fish. You start by buying fish fry packs. When you feed the fry using fish food, they grow into adult fish—then you can sell them to earn money. That profit can be reinvested into new fry packs, helping your aquarium collection expand.

As you keep playing, more kinds of fry become available. You’ll eventually unlock rare and even extremely rare fish fry, including colorful variations that look fantastic in your tank. Throughout the game, you can interact with your fish at any time—making the experience a great way to unwind. Updates will continue to add fresh rare fry and new aquarium options, so there’s always something new to look for.

Game Features

Helpful Strategies

Start-Up Setup and Purchases

At the beginning of the game, you’ll receive five packages, and each package contains four fish. You must make the required package purchases right away—after that, your balance will be $0.

It’s recommended to feed every fish until it reaches adulthood, no matter the rarity, before selling them. After you sell adult fish, you’ll receive money. Repeat this cycle until you fill your tank to its full capacity.

Feed Everything at the Same Time

As your aquarium grows fuller, fish will move around the tank freely. Simply dropping food by tapping/clicking might not catch all of their attention, and some fish may eat it before others can reach it.

Also, keep in mind that your snails can’t swim, so they may not reach most food. To help them eat, lower your other fish to the same level as the snails at the bottom. You can do this by gathering each aquarium inhabitant into the bottom corner (left or right) and then feeding them there.

Sell to Maximize Earnings

Over time, your fish school will begin to grow and change their behavior as they settle into the tank. Keep an eye on your growth pace and timing so you can sell at the right moments to maximize your returns.
