10 Best Betta Tanks 2025 in the United States

The LYPHARD AQUARIUMS Rimless Aquarium boasts a 14.5-gallon capacity, making it spacious enough for bettas and other small aquatic creatures. Its standout feature is the ultra-clear, low iron glass that ensures high transparency (91.5% light transmittance) for a pure and enjoyable viewing experience. The tank's rimless design adds to its aesthetic appeal, providing an unobstructed view of your fish and aquatic plants. The glass is 6mm thick, which, along with professional seam technology and Wacker adhesive bonding, provides robust structure, durability, and leak prevention.

This tank is also versatile, suitable for freshwater and saltwater fish, and can accommodate various aquatic species and plants. However, there are notable downsides. The product does not come with built-in filtration or heating systems, which are critical for maintaining a healthy environment for bettas. You will need to purchase these separately. Additionally, there is no mention of a lid or cover, which can be a concern as bettas are known to jump. Lighting is also not included, so you’ll need to invest in appropriate lighting to showcase your tank’s beauty and support plant growth.

The included EVA foam leveling mat is a nice touch, ensuring the tank is stable and reducing the risk of cracks or leaks. Weighing 24.8 pounds, it’s fairly heavy, which should be considered when deciding its placement. This tank is a visually appealing option for those willing to invest in additional necessary equipment like filtration, heating, and lighting.

The Fluval Flex 9 Gallon Aquarium Kit offers a stylish and modern rectangular tank shape with a curved front that provides a clear and attractive view of your betta fish. Its 9-gallon size is suitable for bettas, giving them enough room to swim comfortably without taking up too much space. One major plus is the powerful 3-stage filtration system, which includes mechanical, chemical, and biological media, helping maintain clean and healthy water — an essential factor for betta health. The tank features adjustable LED lighting with both white and RGB options, controlled by a remote, which supports plant growth and enhances the vivid colors of your betta. This lighting also allows for creative effects, adding a fun element to your aquarium setup.

The product does not include a built-in heater, which is important since bettas prefer warm water (around 78-80°F). You would likely need to purchase a separate heater to maintain stable temperatures. The lid includes an easy-feed top cover opening, making feeding straightforward while helping reduce evaporation and prevent fish from jumping out. The hidden rear filter compartment keeps equipment out of sight, contributing to the clean, contemporary look. This tank is ideal for betta owners looking for a compact yet feature-rich setup with quality filtration and customizable lighting, though you should be prepared to add a heater separately for ideal betta care.

The 20 Gallon Large Fish Tank by TARARIUM appears to be a solid choice for betta and other small aquatic pets. Its substantial size gives your fish ample space to swim, which is a plus for their health and well-being. The tank is made of high-transparent glass, which ensures durability and a clear view of your aquatic pets and plants. The self-cleaning feature and ultra-quiet water pump make maintenance easier and less noisy, a boon for a peaceful home environment.

The inclusion of a water temperature detection system is a great addition, as maintaining the right temperature is crucial for the health of bettas and other tropical fish. Furthermore, the three types of LED lights included in the tank not only enhance the tank's aesthetics but also support plant photosynthesis, ensuring a healthy oxygen level for the fish. The tank is quite heavy at 32.5 pounds, which could be a factor to consider if you plan to move it around frequently.

The tank's features make it a suitable option for beginners and experienced fish keepers alike. Maintaining a balance between stylish design and functional features, it can be an excellent addition to a child's room or any indoor space.
