Our guidance
How do I begin my first aquarium setup?
You can start your journey by selecting one of three available Starter Kits. These include an Empty Tank designed for the tutorial, or pre-configured Amazon or Malawi setups to help you learn the basics of aquarium management.
What is the primary goal for managing my fish population?
Your main objective is to breed healthy and robust animals. By successfully raising them, you can increase the DNA rating of your fishes to the maximum, which is a key indicator of your success as an aquarium manager.
You can increase your available funds by completing various quests. These tasks provide additional budget, which is essential for purchasing new equipment, plants, or fish to further expand and improve your aquarium operations.
Why is it important to monitor fish stress levels?
Keeping stress levels low is vital because stressed fish are prone to getting sick quickly. Furthermore, if your fish remain stressed, they will not reproduce, which hinders your ability to grow your population and improve breeding values.
How do equipment choices affect my aquarium ecosystem?
The quality and performance of components like filters, pumps, and lamps directly impact your ecosystem. Choosing better equipment ensures durability and creates the ideal living conditions necessary for your fishes and plants to thrive.
What is the benefit of decorating the aquarium based on fish needs?
When you create a biotope that aligns with the specific preferences and needs of your fish, they will reward you with better breeding values and produce more offspring, helping you succeed in your simulation goals.
How do I manage my finances while running the aquarium?
You must operate within a limited budget. It is important to browse the Blue World Store for supplies while keeping a close eye on your statistics to ensure you remain financially stable during your aquarium expansion.
Yes, the simulation allows you to cultivate, breed, and trade in both fishes and plants. This mechanic is part of the strategic challenge of managing your aquarium and expanding your collection over time.
Beyond aesthetics, many decorative objects are available to help you design beautiful and unusual biotopes. These items allow you to customize the environment to better suit the specific requirements of your aquatic life.
What does the simulation allow me to influence regarding life cycles?
You can actively influence the complete life cycle of your fishes and plants. By managing their environment and living conditions, you play a direct role in their development, breeding, and overall health within your aquarium.
