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.

The Aqueon LED MiniBow Small Aquarium Kit is a compact 2.5-gallon tank ideal for small fish like bettas, making it a good fit for beginners or those with limited space. Its rectangular acrylic design comes with a black hood and elevated base, giving it a sleek desktop appearance. One of its standout features is the SmartClean Technology, which simplifies water changes to under two minutes, helping maintain water quality and fish health without much hassle. The included power filter with a small cartridge supports clean water, though the filtration capacity is suited mainly for the tank's small size. Built-in LED lighting in the hood provides gentle illumination but may not support live plants needing intense light.

The kit does not include a heater, which is an important consideration since bettas require stable warm water around 78°F; buyers may need to add a separate heater for optimal betta care. It also lacks substrate and decorations, so you'll want to add gravel or sand and plants or hiding spots to create a comfortable environment. The tank cover helps prevent fish from jumping out and reduces evaporation.

This aquarium offers a straightforward setup experience with a helpful guide and comes with basic essentials like fish food and water conditioner. Although its small size limits the space for active swimming and fewer decorations, it is a solid choice for those starting with bettas or keeping a small desktop aquarium who appreciate easy maintenance features.

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.
