10 Best Betta Tanks 2025 in the United States

The Aqueon Aquarium Fish Tank Starter Kit is a solid choice for anyone looking to start their aquarist journey, particularly for betta fish enthusiasts. With a 10-gallon capacity, it's spacious enough to house a betta comfortably, along with some plants and decorations to create a vibrant environment. The included low profile LED lighting enhances the tank's aesthetic and brings out the colors of both the fish and the tank's features.

A major strength of this kit is its all-in-one setup. It comes with essential equipment like a QuietFlow power filter, a preset heater that maintains an ideal temperature for tropical fish (including bettas), and even samples of fish food and water conditioner. This makes it user-friendly, especially for beginners, as they won't have to search for individual components.

The filter's red LED light that flashes to indicate when to change the cartridge is a thoughtful feature, helping owners maintain water quality without constant monitoring. The rectangular shape allows for good light and water circulation, which is beneficial for fish health. There are a few drawbacks to consider, such as the heating element being preset to 78 degrees, which may limit customization for some users. Additionally, while the glass tank looks great, it can be heavier and more prone to breaking than acrylic tanks, making placement and maintenance slightly more challenging. The 90-day warranty is relatively short, which can be a concern for long-term investment. Despite these minor downsides, this starter kit is an excellent entry point for novice aquarium keepers, providing everything needed to create a thriving betta habitat.

The NICREW 2.5 Gallon Nano Nature Aquarium Kit is a compact and stylish choice for anyone wanting a small betta tank or a home for shrimp and small fish. Its 2.5-gallon size is perfect for limited spaces like desks or countertops, making it easy to place almost anywhere. The tank is made of high-clarity, rimless low-iron glass, which means you get a clear, attractive view of your aquatic friends without distractions from thick frames. It comes with a lid to keep your fish safe and reduce water evaporation.

The included filtration system is simple and effective, helping maintain clean water without much effort, which is great for beginners. An LED light is also provided to support plant growth and highlight your tank’s colors. However, the kit does not include a heater, which is an important consideration if you plan to keep bettas, as they prefer warm water. You'll need to buy a small aquarium heater separately to maintain the right temperature.

The rectangular shape offers a comfortable swimming space for bettas but keep in mind that 2.5 gallons is on the smaller side, so regular water changes are essential to keep your fish healthy. This all-in-one kit provides a neat, easy setup for small aquatic pets but requires an added heater for proper betta care.

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.
