Ornamental fish tanks are a beautiful way to house aquatic animals and plants in a home environment. The tank typically consists of one or more transparent sides, filled with water, and is used to house fish, invertebrates, amphibians, and aquatic plants. Many people have been fascinated by fish tanks for years, but in the past, they often faced the issue of fish dying quickly because they didn’t know the right conditions for their survival. In this article from teketrek , we will outline how to properly set up an ornamental fish tank to ensure a healthy environment for the fish and an attractive display.
1. Choosing the Right Location for the Fish Tank
Selecting the proper location for the fish tank is the first step in ensuring the success of the aquatic environment. The tank should not be placed in direct heat sources or in front of windows, as excessive heat can lead to algae growth on the glass walls of the tank. Additionally, there should be enough space around the tank to facilitate maintenance and handling of the tank from all sides. It’s important to allow ample space for water changes and to minimize the risk of spills.

2. Choosing the Right Size Tank
When choosing the size of the tank, it is important to consider that tanks come in various sizes and shapes, whether for saltwater or freshwater fish. Sizes range from 1 gallon to 200 gallons. For beginners, it is recommended to choose a tank that ranges between 10 to 20 gallons. It’s also important to consider the materials used to make the tank, such as:
- Glass: Provides a clear view, but it is heavy and can break easily.
- Acrylic: Lighter and more durable than glass, but prone to scratching.
- Coated Steel: Strong but requires care to avoid rust.
Choosing the right tank is crucial for creating a healthy environment for your fish and achieving a beautiful display in your home.
3. Setting Up the Filter and Lighting System
Filter: The filter is an essential part of the tank for maintaining water purity. It removes debris and floating particles by filtering the water through materials such as sponges or charcoal. Various filters are available, including box filters, which are more economical and work well with smaller tanks.
Lighting System: Balanced lighting is necessary for the health of both the fish and plants. Strong lighting can cause algae buildup, while dim lighting may make it difficult to see the fish. LED lights are recommended as they provide bright illumination and have a long lifespan. It is advisable to use 1-2 watts per gallon of water to achieve the ideal lighting.
4. Choosing Suitable Plants and Decorations for the Fish
Aquatic plants not only add a beautiful touch to the tank but also help improve water quality through photosynthesis. There are two types of plants:
- Plastic Plants: Easier to maintain and come in a variety of colors, but they do not offer environmental benefits.
- Live Plants: They improve the water environment, provide oxygen for the fish, and help balance the tank’s ecosystem.
As for decorations, a balanced design should be chosen to ensure the fish have enough space to move and hide. Rocks, shells, and figurines can be used, but they must be made from safe materials without sharp edges that could harm the fish.
5. Adjusting Water Temperature and Quality
Temperature plays a significant role in the health of the fish. Most fish prefer temperatures between 20-30°C. To regulate the temperature, you can use a heater suitable for the tank size. It’s important to ensure that the temperature change is gradual and does not exceed one degree Celsius per day to avoid harm to the fish.

6. Gradually Adding Fish to the Tank
Once the tank is set up properly, the next step is to add fish that meet the tank’s environmental requirements. If you’re a beginner, here are some fish that are easy to care for:
- Goldfish: Beautiful and easy to care for.
- Barbs: Active and suitable for most tank environments.
- Tilapia: Calm and tolerant of various conditions.
Make sure the fish are compatible with the tank’s conditions, such as temperature, pH levels, and overall behavior, before adding them gradually to the tank.

Tips for Caring for and Maintaining the Fish Tank
- Feeding the Fish: Feed the fish the recommended amount twice a day.
- Monitoring Behavior: Ensure that the fish are active and healthy.
- Cleaning the Tank: Regularly remove food scraps and unwanted materials from the tank.
Routine Maintenance for Fish Tank Health
To maintain a healthy environment for the fish, regular maintenance is essential, including:
- Cleaning the Filter: Check the filter regularly and ensure it operates efficiently.
- Water Changes: Replace 10-15% of the water weekly to maintain water quality.
- Monitoring Plants: Ensure that the aquatic plants are healthy and remove any wilted leaves.
- Monitoring Fish Health: Observe the fish regularly for any signs of stress or illness.
Conclusion
Setting up an ornamental fish tank is a fun and rewarding experience that enhances the beauty of your home and creates a healthy aquatic environment for your fish. By following these steps and tips, you can create a beautiful and healthy environment for your ornamental fish, ensuring a long and happy life for them.
