10 Best Fish Tanks 2025 in the United States

The Aqueon LED MiniBow 5 Gallon Aquarium Kit is a compact, rectangular fish tank made from acrylic, which is lightweight and durable. Its 5-gallon size makes it perfect for small fish or beginners looking for a simple home aquarium that fits nicely on a desk or shelf. One standout feature is the SmartClean Technology integrated into the power filter, which simplifies water changes by allowing you to clean the tank in under two minutes — a great help for anyone new to fish care.

The kit includes everything you need to get started, such as a low-profile LED hood for lighting, an elevated base for stability, a filter cartridge, fish food, water conditioner, and an easy-to-follow setup guide. This makes it especially suitable for first-time fish keepers or families with kids. While the 5-gallon size limits the number and type of fish you can keep, it’s ideal for small breeds and helps maintain water quality more easily. The rectangular shape offers a traditional aquarium look and decent swimming space for small fish.

A minor downside is the relatively short 90-day warranty, which might feel brief compared to some competitors. Also, because it's a smaller tank, it requires attentive maintenance to keep fish healthy. If you want a simple, attractive, and user-friendly small aquarium with convenient filtration and lighting features, this kit is a solid choice.

The Tetra Aquarium 20 Gallon Kit is a solid choice for freshwater fish enthusiasts, providing a substantial 20-gallon glass tank. The size is suitable for various fish species, offering a spacious environment without being overly large. The rectangular shape is standard and fits well in most indoor spaces. The glass material ensures durability and clear visibility for observing your fish.

The kit comes with a low-profile, hinged hood and an energy-efficient LED lighting system, which simulates natural daylight and enhances the visual appeal of the tank. The internal filtration system is a standout feature, combining mechanical filtration to catch debris and chemical filtration with Ultra-Activated Carbon to remove odors, discoloration, and toxins, ensuring a clean and healthy environment for your fish. Additionally, the kit includes an aquarium heater and thermometer, which are essential for maintaining the right water temperature for tropical fish.

The setup is straightforward, making it accessible even for beginners. However, the tank's weight, at over 34 pounds when empty, may be cumbersome for some to handle during setup or cleaning. Also, while the filtration system is generally effective, some users might find it necessary to upgrade or supplement it for larger or more delicate fish. This kit offers a comprehensive and user-friendly solution for creating a thriving freshwater fish habitat, though be prepared for the initial weight and potential future filtration upgrades.
