What is a 20 gallon long tank?
A 20-gallon long tank is a very popular type of planted tank. Although you have a couple of options when choosing a tank, a long tank is typically the one that most people think of when they think about aquariums. In other words, it’s a classic – and for good reason too.
In terms of specifications, a 20-gallon tank typically measures 30″ wide, 12″ tall, and 12″ deep. Sometimes, it can also be 13″ tall and 13″ deep.
So, why exactly is it so popular? Simply put, its width of 30″ means there are a lot of things that you can see in the tank. Since it’s 12″ tall, light can easily penetrate the bottom, which means you can grow plants very easily, whether it’s the saltwater or the freshwater variety. This is very helpful to any beginner who’s just starting to get into the planted tank hobby.
How long is a 20 gallon long planted tank?
As mentioned above, 20 gallon long tanks are typically around 30 inches long. This gives fishes enough area to move around, and plants more space to propagate.
Other than the long tank, there are also two other variants of the 20 gallon, namely the high tank and the extra high tank. The high tank typically measures 24″ wide, 16″ tall, and 12″ deep. Obviously, it’s narrower than the long version but it makes up for it with the height. It’s also quite popular since it has a smaller footprint than the traditional long tank.
The extra high tank, on the other hand, is twice as tall as the traditional 20 gallon long planted tank. At 24″ tall, it’s not as popular as the two other variants, but there are still a lot of aquarists who are interested in this tank.
How do you Aquascape a 20 gallon tank?
Aquascaping a 20 gallon tank is certainly fun for everyone. With a 20-gallon allowance, you can have a large selection of fish to choose from, as well as enough room for various plants.
The most important thing is preparing your aquascape. First of all, determine what budget you’re comfortable with. Obviously, a bigger budget means you can do a lot more things, but you don’t need a huge budget to make something great. Even with just a small budget, you can already create a respectable and beautiful aquascaped 20-gallon planted tank.
Second, consider the different apparatuses that you need for the tank. For instance, what kind of filter will you be using? Is it a sponge filter? A canister filter? A hang-on-back filter? Do you need to include a heater in the tank? Remember, there are some fishes and plants that can’t survive in colder temperatures, so keep this in mind.
Last but not the least, it’s time to select the plants that you’ll be putting in the tank. This mostly depends on your preferences, but you should consider your expertise and skills as well. Don’t choose plants that are hard to take care of if you’re still a beginner. Opt for easy plants to care for, such as java ferns, anubias, or amazon swords.
