40 to 54 Gallons Fish Tank

The bigger the aquarium, the better it is for your fish. In aquariums larger than 40 gallons, the increased water volume helps dilute toxins, maintain temperatures and stabilize nitrogen cycles, all key factors in keeping your fish healthy and happy. Petco has a wide variety of large tank choices to fit every style and budget, from standard 40 gallon fish tanks and 40 gallon breeder tanks all the way up to 50 gallon fish tanks and beyond.

FAQs About 40 to 54 Gallon Fish Tanks

A 50 gallon aquarium can weigh upwards of 440 pounds once you’ve filled it with water and all the décor, substrate and accessories needed to make an aquarium a home. Before you invest in a larger aquarium, make sure your floor can support the weight. And if you rent your home, check your lease. Some apartments and condos limit the size of aquariums allowed.

Even tanks that hold the same volume of water can have very different dimensions. A standard 50 gallon aquarium is generally around 36” L x 20” H x 15” W, while breeder aquariums tend to have a wider base.

Breeder tanks typically have a wider base or footprint than standard aquariums. Dimensions vary by manufacturer and model, but a 40 gallon breeder aquarium averages around 36” L x 16” H x 18” W.

Gravel plays an important role in keeping your tank healthy because it is home to beneficial bacteria that help reduce toxins in the water. To ensure good coverage and depth, you’ll need about 1 to 2 pounds per gallon of water to achieve a 1- to 2-inch base.
