10 Best Betta Tanks 2026 in the United States

The biOrb Classic 60 is a stylish 16-gallon round acrylic aquarium designed for tabletop display, offering a full 360-degree view of your betta fish. Its acrylic build is a strong point—it’s lighter and clearer than glass and helps keep water warmer, which is beneficial for bettas that need stable temperatures. Although it doesn't include a built-in heater, acrylic’s insulation can help maintain warmth, but you may still need a separate heater depending on your room temperature.

Its patented 5-stage filtration system is a major advantage, as it effectively keeps water clean and healthy with biological, mechanical, and chemical filtration plus oxygenation, all neatly hidden at the tank’s bottom for easy maintenance. The included multi-color LED lighting with remote control adds a fun, mood-enhancing feature, allowing you to adjust colors and brightness or set day-night cycles that can reduce algae and support fish well-being.

The round shape, while visually appealing, limits swimming space compared to rectangular tanks and may make decorations and plant placement a bit tricky. The tank comes complete with an air pump, water treatments, and filter media, so you’re mostly ready to go—just add decorations and your betta. This setup suits someone looking for a low-maintenance, attractive home for their betta, especially if they enjoy customizable lighting, while keeping in mind the need to monitor temperature and the challenges of aquascaping in a round tank.

The Aqueon LED MiniBow Small Aquarium Fish Tank Kit with SmartClean Technology is a 5-gallon tank designed for small fish, making it a good choice for bettas. One of its standout features is the SmartClean Technology, which allows for quick and easy water changes, significantly improving water quality and ensuring a healthier environment for your fish. This feature is particularly convenient for first-time fish keepers and busy individuals.

The tank comes with essential components such as a power filter, filter cartridge, fish food, water conditioner, and a setup guide, making it a comprehensive starter kit. The rectangular shape and acrylic material make the tank durable and lightweight, and it also has a low-profile LED hood that provides adequate lighting for the inhabitants. The elevated base adds a stylish touch and allows for better viewing. However, the kit does not include a heater, which is an important consideration for bettas as they require warm water to thrive. You may need to purchase a heater separately.

While the tank size is adequate for a single betta, it may be too small for multiple fish or larger species. The 90-day warranty offers some peace of mind, though it's relatively short compared to other products. This tank is best suited for novice fish keepers or those looking for a simple, compact aquarium setup for small fish like bettas.

The Aqueon Aquarium Starter Kit offers a solid setup for anyone looking to keep betta fish or similar tropical freshwater species. Its 20-gallon rectangular glass tank provides ample space, which is great because bettas thrive in larger, well-maintained environments rather than cramped bowls. The included SmartClean internal power filter is easy to use and helps maintain clean water, which is crucial for betta health. The preset 50W heater keeps the water at a stable 78°F, ideal for tropical fish like bettas that need consistent warmth.

The low-profile hood with cool white LED lighting gives your tank a clean look and appropriate illumination, plus the feeding door adds convenience. Being a complete starter kit, it comes with helpful extras like a thermometer, fish net, fish food, and water conditioner, making setup straightforward for beginners. One minor drawback is that the filtration is internal, which can take up some space inside the tank and might need more frequent cleaning compared to external filters. Also, while the LED lighting is adequate, it doesn’t offer adjustable color options that some hobbyists might prefer for plant growth or aesthetic customization.

This kit incorporates all the essentials needed for a healthy betta tank with easy maintenance and reliable equipment, making it well suited for beginners or those wanting a hassle-free setup.
