This article will explain how big a 40 gallon breeder tank is.
A 40 gallon breeder tank is one of the most common sized aquariums used by aquarists around the world.
The “breeder” style tank is used as a home aquarium for people who are interested in breeding various types of fish.
What’s unique about a 40 gallon breeder tank is its actual size and dimensions as these tanks are designed a bit different than a standard size aquarium.
These tanks generally have a wider footprint than other tanks of the same size.
How Big Is A 40 Gallon Breeder Tank?
The actual dimensions of a 40 gallon breeder tank are 36 inches long x 18 inches wide x 15 inches tall. This tank will hold 42 gallons of water. The dimensions of the tank is for the glass only and does not include the canopy or top, plastic trim, or any other equipment.
The reason for these unique dimensions is that it provides the proper space for fish to breed and due to the tank being so short (16 inches), it makes it easier for you to reach into the tank.
If you plan on buying a 40 gallon breeder tank, it’s important to have the right sized stand or cabinet for it and plan a proper space for it in your home.
How much does a 40 gallon breeder fish tank weigh?
Depending on the type of material the aquarium is built with, the weight can vary. Certain glass can weigh more than others and thicker glass will weigh more than thinner glass.
Many aquariums are made using acrylic which weighs less than glass.
A 40 gallon breeder aquarium is considered to be a medium sized fish tank and can be difficult for 1 person to carry.
On average, a 40 gallon breeder tank weighs between 55-60 pounds when empty.
One filled with water, the aquarium will weigh around 400 pounds.
The weight of water is 8.33 pounds per gallon. If you are using saltwater, it weighs 8.5 pounds per gallon.
This does not include any equipment or decorations you may put in the tank. It is recommended to use a proper aquarium stand that is suitable for the dimensions and weight of the tank.
Uses for a 40-gallon breeder tank
Not only is a breeder tank great for aquarium fish, but it is commonly used for smaller reptiles and bearded dragons. People often keep Blue-tongued skinks, corn snakes, baby bearded dragons, and more in a breeder tank.
Most people used these tanks for freshwater aquariums but they work well for saltwater aquariums as well.
Can you put a 40-gallon breeder tank on a table?
It’s recommended that you only use an aquarium stand for a tank of this size. When filled with water and equipment, a 40 gallon breeder can weigh over 400 pounds.
A normal table that has not been reinforced will not be able to support the weight. Not only is this a safety concern, but it can cause a lot of damage and it would be a costly mistake.
If you don’t have the option of using an aquarium stand, you can have a custom one built or buy a second hand stand that another hobbyist may be selling. As long as the stand can support all edges of the tank and support the weight, it can be used.
Other 40 gallon tank sizes
The 40 gallon aquarium is available in other dimensions as well. As mentioned, the breeder style tank measures 36” x 18” x 15”. It is also available as a 40 gallon long style which has the dimensions of 48” x 12” x 16”. It still holds 40 gallons of water just in a different shape.
In fact, if you have a custom 40 gallon aquarium built for you, it can be multiple dimensions that equal 40 gallons.
To calculate the aquarium volume, simply multiply the height, length, and width together and divide by 231.
Using the 40 gallon breeder tank as an example, multiply its dimensions together and divide by 231.
36 x 18 x 15 = 9,720 / 231 = 42 gallons. The 40 gallon breeder is actually a 42 gallon tank.
Using the 40 gallon long tank as an example, multiply its dimensions together and divide by 231.
48 x 12 x 16 = 9,216 / 231 = 39.9 gallons.
Using this formula you can calculate aquarium volume of any size.
