The best fish tanks suitable for betta fish should have the following characteristics:
Size: The size of a betta fish tank should not be too large. Generally, a fish tank with a length of 20 - 30 centimeters is sufficient for keeping one betta fish. Although a small tank can allow betta fish to survive, a larger tank enables them to live better. A fish tank with a minimum height of 12 centimeters is recommended, and a 15 - 20 centimeter tank is more ideal.
Material: A glass fish tank is a good choice, especially an ultra-clear glass tank. Due to its high transparency and stability, it helps keep the water quality clean.
Decorations: You can put some decorations such as aquatic plants, stones, or artificial rockeries in the fish tank. However, be careful not to place sharp objects to avoid scratching the betta fish.
Filter: Although betta fish don't need a powerful filter, a silent filter can help keep the water quality clean. It is recommended to use a filter with a moderate power to avoid disturbing the betta fish's rest.
Heater: The suitable water temperature for betta fish is 24 - 28°C, so a heater is essential. Place the heater on the side of the fish tank to avoid affecting the betta fish's movement.
Lighting: An integrated double-sided light box can provide good lighting effects and also facilitate water changes.
Filtration System: An integrated bottom sand filtration system takes up little space and is easy to maintain. It is suitable for keeping all kinds of betta fish.
