10 Best Betta Fish Tanks 2025 in the United States

The NICREW 2.5 Gallon Nano Nature Aquarium Kit is a compact and attractive choice for betta fish or other small aquatic pets. Its 2.5-gallon size is suitable for single bettas, which prefer smaller tanks but still need enough space to swim comfortably. The rimless crystal-clear glass offers a modern look and excellent visibility, letting you enjoy your fish and plants easily. The kit includes a slim filter designed to keep the water clean with minimal effort, which is important since bettas need stable, clean water to stay healthy. It also comes with a nano clip-on LED light that supports live plants and enhances the tank’s natural beauty.

This kit does not include a built-in heater, a key component for maintaining the warm water conditions bettas require. Therefore, a separate heater should be purchased to keep the temperature stable around 76-80°F. The included tank cover helps prevent fish from jumping out and reduces evaporation. Starter gravel and rock decorations provide a simple base for plants and hiding spots, but you might want to add more plants or decorations to enrich the environment and better mimic your betta’s natural habitat.

The included leveling mat assists with setting up the tank on uneven surfaces, making this kit beginner-friendly. It is well-suited for those new to betta keeping or anyone wanting a stylish, low-maintenance desktop aquarium, provided that a heater is added for a healthy betta habitat.

The Aqueon Aquarium Fish Tank Starter Kit is an appealing option for beginners looking to start a 10-gallon aquarium, especially for keeping betta fish. One of its biggest strengths is that it comes complete with all the essential equipment, including a glass tank, filtration system, heater, and LED lighting. This makes the setup process straightforward for those new to fishkeeping. The low-profile LED hood provides bright lighting that enhances the visual appeal of the aquarium, which is crucial for showcasing live plants and decorations, creating a lively environment for your fish.

The filtration system is user-friendly with an LED indicator that lets you know when it's time to change the filter cartridge, helping maintain a clean habitat for your fish. The preset heater is another practical feature, keeping the water temperature consistently at a comfortable 78 degrees, which is ideal for tropical fish like bettas.

However, there are a few drawbacks. The tank size of 10 gallons might be limiting if you plan to expand your fish collection, as bettas require space to thrive and coexist with other fish. While the starter kit includes a variety of essential items, some users might find the quality of certain components like the heater or filter may not meet their long-term needs if they decide to upgrade their setup later on. Additionally, while it’s easy to set up, maintaining water quality and temperature is crucial and may require more attention from beginners who are unfamiliar with aquarium care. The 90-day warranty offers some peace of mind, but it’s worth noting that some users have reported issues with the filter or heater not lasting beyond this period.

The Aqueon Aquarium Fish Tank Starter Kit is well-suited for first-time aquarists seeking a manageable and enjoyable way to introduce fishkeeping into their lives, particularly with betta fish. Just keep in mind the limitations in size and consider your long-term plans for the aquarium.

The NICREW 2.5 Gallon Nano Nature Aquarium Kit is a great pick for anyone looking to keep a single betta fish or other small aquatic creatures like shrimp in a compact and stylish setup. Its 2.5-gallon size is ideal for bettas, providing enough space without overwhelming desks or small rooms. The tank uses high-clarity, rimless glass that gives a clean and modern look, making it easy to enjoy your fish and plants from all angles.

Filtration comes built-in with a slim, simple filter that helps keep the water clear and healthy with minimal fuss, which is perfect if you want a low-maintenance tank. The kit also includes a nano clip-on LED light, supporting plant growth and improving the tank’s appearance. A separate heater will be needed to maintain the right water temperature for bettas, as one is not included.

A solid lid is included, which helps prevent fish from jumping out and reduces evaporation. The package does not include substrate or decorations, so you’ll need to add gravel or sand and plants or ornaments yourself to create a comfortable environment. The starter guide is a nice touch, especially for beginners, guiding you through setup and care. This aquarium is suitable for beginners or anyone with limited space who wants a neat and clear display for a betta or other small aquatic pets, with the consideration of purchasing a heater and personalizing substrate and decorations.
