10 Best Betta Fish Tanks 2025 in the United States

The Aqueon LED MiniBow 5-Gallon Aquarium Fish Tank Kit is a good choice for those looking to start a betta fish tank. Its 5-gallon size is suitable for bettas, offering ample space for them to swim. The SmartClean Technology is a standout feature, making water changes quick and easy, which is a significant benefit for maintaining a healthy environment for your fish.

The tank also comes with a power filter and a small filter cartridge, which help in keeping the water clean and clear. The low-profile LED hood provides sufficient lighting for the tank, enhancing its appearance and making it easier to observe your fish. Additionally, the tank includes an elevated base, which adds to its aesthetic appeal and stability.

The kit comes with everything you need to get started, including fish food, water conditioner, and a setup guide, making it user-friendly for both beginners and experienced fish keepers. On the downside, some users may find the acrylic material less durable compared to glass tanks. Also, the included filter may not be the quietest, which could be a concern for those sensitive to noise. The tank cover is basic, and while it helps reduce water evaporation, it may not be entirely secure against curious pets or young children. The included decorations and plants are minimal, so you might want to invest in additional decor to create a more enriching environment for your betta. This tank kit is well-suited for those new to fish keeping or those looking for a hassle-free setup.

This 5-gallon glass aquarium from COOSPIDER is designed with betta fish and small shrimp in mind, making it a good starter tank. Its size is suitable for a single betta, providing enough space for comfortable swimming without taking up too much room. The tank features a whisper-quiet triple filtration system that combines water circulation, oxygenation, and filtration, which also has a self-cleaning design to reduce maintenance by about 70%. This is a strong point, as clean water is vital for bettas. The glass is thick and clear, ensuring a sharp view of your fish, and the tank includes customizable 3-color LED lighting that highlights the tank and its inhabitants nicely both day and night.

Another helpful feature is the Smart TempGuard, which monitors water temperature in real-time—a key factor for bettas that prefer stable warm water. Since bettas require consistent warmth around 78-80°F, adding a heater is necessary to fully meet their care needs. There is also no included tank cover, which is important to prevent your betta from jumping out. The flip-top design appears user-friendly for feeding and maintenance.

While decorations and substrate are not part of the kit, the tank’s size and lighting make it easy to add plants and accessories to create a comfortable environment. With strong filtration, temperature monitoring, and good visibility, this tank is suitable for beginners who are prepared to add a heater and cover separately to provide a complete environment for their betta.

The JPHYLL 2.2 Gallon Fish Bowl is a compact and smart aquarium suitable for betta fish and other small freshwater species. Its modest size provides enough space for a single betta but might be tight if you want to add more fish or decorations. The tank is made from thick, clear float glass offering a nice viewing experience and sturdy build.

It includes a 3-in-1 quiet pump that handles filtration, oxygenation, and water circulation, which helps keep the water clear and healthy—important for bettas that need clean water but don’t like strong currents. The tank also features a temperature display to monitor conditions; however, it does not have a built-in heater, so you will need to add one during colder months to maintain stable warmth. Lighting is a standout feature here, with 7-color auto-looping LED lights that can be adjusted manually or automatically, adding visual appeal and some light for live plants if you decide to add them. The included plants are artificial, so live plants and substrate are not supplied and will need to be added separately if desired.

A removable blue board acts as a tank cover to prevent your betta from jumping out, but the overall tank design is rimless, requiring careful handling to avoid spills. The integrated aromatherapy humidifier is an interesting extra that can enhance room ambiance, although it is unrelated to fish care. Assembly and maintenance are made easy with clear instructions and accessible features. Due to the small water volume, frequent water changes and proper temperature control are necessary to keep your betta comfortable. This aquarium provides a modern, space-saving option with smart features, making it ideal for beginners seeking a stylish, low-maintenance setup while supplementing heating and live décor.
