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.

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.
