Description
Idle Fish Aquarium Mod APK is an entertaining strategy game that's easy to pick up. Here you can build and grow your own oxygen production and sales operation.
Idle Fish Aquarium puts you in charge of a factory packed with modern technology and advanced production lines as you build your aquarium empire. Your little ocean is home to plenty of charming, colorful fish, and the fish you keep are what generate the oxygen. The game uses simple 2D graphics with a playful, cute cartoon style. The animations run very smoothly, and the gameplay is genuinely hard to put down.
Manage Your Special Production Line
In this game, you manually run the oxygen production line that connects fish and algae. Algae produce oxygen bubbles, and the fish carry them into the machine, where they're turned into oxygen tanks. Your job is to wake the fish up and get them working by tapping the screen so they gather oxygen. When you're busy or simply don't have time to play, you can let the fish collect automatically with a single, easy setting. Resources can be gathered anytime and anywhere, so you can grow your empire and rake in plenty of money.
Many Fun Fish Species to Discover
Fish are key to moving oxygen from the algae, and you can choose from a wide variety of species to put to work. The lineup ranges from everyday favorites like goldfish and clownfish to quirky, unusual-looking ones such as pizza fish and panda fish, and more. Every species works at its own productivity rate, so you'll need to put in effort to unlock higher levels for each one.
Upgrade Your Factory
To produce more oxygen, you'll need to upgrade your production line. Upgrades help you earn more money, work more efficiently, and raise the quality of your products, which speeds up your earnings. Deliver your products to partners and work with them to refine and expand your production model.
Key Features
- Decorate your aquarium with a broad selection of decorations. The more beautiful an item is, the higher its price, so think carefully about what you buy to stay within your budget.
- Upgrade production plants: invest in equipment to bring your production lines to a higher level and make your products better than ever.
- A wide range of adorable fish to choose from. Each fish's working capacity depends on its level, and they'll help you earn the money you need to build your automated line.
- Produce oxygen from fish and algae, transport it into oxygen tanks, and sell to partners who need it. Work with them to scale up your production even further.
- The game is simple and idle-friendly. If you don't have time to play, the fish can collect automatically, and they still gather resources for you whenever you need them.
