When it comes to creating a suitable habitat for your arowana fish, one important aspect to consider is the lighting. Proper lighting not only enhances the visual appeal of your tank but also plays a crucial role in the overall health and well-being of your arowana. With a wide range of lighting options available in the market, it can be overwhelming to choose the best lighting for your arowana fish. In this comprehensive guide, we will explore the different types of lighting available and help you make an informed decision for your arowana tank setup.

1. Natural Lighting:

Before we delve into artificial lighting options, it is important to understand the significance of natural lighting for your arowana fish. Arowanas are native to the tropical regions of Southeast Asia, where they thrive in bright and natural sunlight. If possible, placing your tank near a window or providing indirect sunlight can greatly benefit your arowana's overall health. However, it is important to note that direct sunlight can lead to excessive heat and algae growth, so it is crucial to strike a balance.

2. LED Lighting:

LED (Light Emitting Diode) lighting has gained immense popularity among aquarium enthusiasts due to its energy efficiency and versatility. LED lights come in a wide range of colors, allowing you to create various lighting effects to enhance the aesthetic appeal of your arowana tank. Additionally, LED lights produce less heat compared to traditional lighting options, reducing the risk of overheating your tank. When choosing LED lights, opt for ones specifically designed for aquarium use, as they provide the necessary spectrum of light for optimal growth and coloration of your arowana.

3. Metal Halide Lighting:

Metal halide lighting is another popular choice among arowana fish keepers. These lights emit a high-intensity white light that closely resembles natural sunlight, providing excellent color rendition and promoting the growth of live plants in your tank. Metal halide lights are particularly beneficial for tanks with live plants, as they provide the necessary light intensity for photosynthesis. However, it is important to note that metal halide lights produce a significant amount of heat and may require additional cooling mechanisms to maintain the optimal temperature in your tank.

4. Fluorescent Lighting:

Fluorescent lighting has been a staple in the aquarium industry for many years. These lights are available in a range of colors and are relatively affordable compared to other lighting options. While fluorescent lights may not offer the same intensity as LED or metal halide lights, they are still a viable option for arowana tanks, especially if you have a limited budget. It is important to select fluorescent lights with a spectrum that closely matches the natural sunlight to ensure the well-being of your arowana fish.

5. Combination Lighting:

Many aquarists prefer to combine different lighting options to achieve the desired lighting effects in their arowana tanks. For example, a combination of LED lights and metal halide lights can provide both the energy efficiency of LEDs and the color rendition of metal halide lights. It is important to carefully plan and balance the lighting setup to meet the specific requirements of your arowana fish and the plants in your tank.


Choosing the best lighting for your arowana fish tank is a crucial aspect of creating a suitable habitat for your beloved fish. Whether you opt for LED, metal halide, fluorescent, or a combination of lighting options, it is important to consider the specific needs of your arowana and the plants in your tank. By providing the right lighting, you can enhance the visual appeal of your tank while promoting the health and well-being of your arowana fish.
