Tetra 55 Gallon Glass Aquarium – Rectangular Tank

The Tetra 55 Gallon Aquarium is a large, sturdy glass tank built for aquarists who want to create a spacious and dynamic aquatic environment. Its rectangular design gives you plenty of room for schooling fish, larger species, or ambitious aquascapes.

With 55 gallons of water volume, this tank offers excellent stability—water parameters are far less likely to swing, which reduces stress on your fish and makes long-term care easier. It’s the perfect choice for anyone who wants to move beyond smaller community tanks and experience what a big aquarium has to offer.

Because it’s sold as just the tank, you’ll need to add your own filter, heater, and lighting. This also means you can tailor the setup exactly to your style, whether that’s a lush planted aquarium, a colorful tropical community, or even a semi-aggressive species tank.

👉 In short: a reliable, large-capacity tank that opens the door to endless possibilities in fishkeeping—perfect for serious beginners ready to go big, or experienced aquarists looking for more space.
