Things to Consider Before Buying a 20 Gallon Fish Tank
As we said above, there are several things to keep in mind when getting a tank for your fish. There are things to know, things to look out for, and things you definitely don’t want to do. Let’s start with…
Two main components make up a tank. They mostly differ on minor things such as aesthetics or how prone they are to scratches, but whichever you choose should be due to personal preference, for either of them is the best choice if you know how to take care of them. We will analyze each.
Plastic/Acrylic –The first and most common type of material you’ll find on the market is plastic. It’s usually cheaper, lighter, and easier to move around. Acrylic is a slightly more premium version of plastic that doesn’t scratch as easily but is still prone to it if not handled with care. Both are pretty sturdy overall.
Glass – Glass is the more “traditional” material for fish tanks and is a bit heavier but also much more scratch-resistant than either plastic or acrylic. It can also be found in different shapes and sizes, unlike acrylic which is only available in one solid color (translucent). Glass tanks are definitely harder to move around.
After you’ve decided on the material, it’s time to start looking at prices. 20 gallon fish tanks can range from as low as $100 to upwards of $250, and sometimes even more. It all depends on the brand, materials used, features included, additional equipment needed…etc.
The best way to save money when buying a new tank is to look for bundled kits that include everything you need to get started with your new aquarium setup. These usually come with light, filter, gravel, and sometimes even fish food or decorations. They cost more upfront but end up being cheaper in the long run since you don’t have to buy each item separately.
A good 20 gallon fish tank kit is Marina LED Aquarium Kit which includes LED lighting, a filter with free media, a thermometer, and an aquarium fishnet.
Another thing to consider when buying a 20 gallon fish tank is what kind of stocking plans you have. This will determine the type and size of fish you can keep in your tank. For example, a 20 gallon long tank is better for keeping taller fish while a regular 20 gallon tank is better for a more diverse variety of smaller fish.
Stocking will also determine the size, shape, and filtration system you need. If you’re planning on keeping small fish like goldfish or bettas, then a simple rectangular tank with a hang-on-back filter will suffice. But if you want to keep larger fish like cichlids or freshwater sharks, then you’ll need a bigger tank with more powerful filtration.
Last but not least, you’ll need to find a place to put your new aquarium. This means finding a 20 gallon fish tank stand that can support the weight of your tank and all the water inside it. A 20 gallon fish tank full of water can weigh over 150 lbs, so make sure the stand is sturdy and won’t collapse under the weight.
You can find stands made specifically for 20 gallon tanks or you can get a generic stand that’s rated for a higher weight capacity. Just make sure it’s stable and won’t wobble when you put your tank on it.
Style and Design
People sometimes tend to go after tanks that would look the best rather than high-quality ones. Although most tanks indeed have a very standard look and it’s usually hard to find something unique and especially good-looking, but that doesn’t mean you should jump at the first modern fish tank you see.
However, don’t think that you should also opt for a bad-looking one either because it can certainly ruin your setup. Nevertheless, there’s a small selection of tanks that have the aesthetics part down with good functionality and even come at a reasonable price. Certain brands are known for their aesthetic choices and some tanks that dominate the market for looks.
We managed to find several tanks with these characteristics and just below you’ll find them reviewed for your convenience. All and all, a cool fish tank is only part of what you need and you should find a balance between all qualities of a tank.
What Sets a Good Fish Tank Apart?
Technically, there’s not anything that just screams this is a good tank. It’s rather a collection of qualities and features that are combined with good manufacturing and good design. The main giveaway of a tank’s quality is the price.
There are no cheap tanks that are well built. It’s logically impossible too because good components cost money and no manufacturer would make a product that’s made with good products and sell it for less than they used to build it.
Besides the price, something else that’s quite important is sturdiness. If you realize that the product is flimsy or shakey, it’s almost guaranteed that it’s going to disappoint in performance and might even break, crack or leak when you put the water in. Either way, a good tank will show its quality right from the unboxing and then prove itself in the months and years to come.
After considering all of these factors, the best 20 gallon fish tank kit is the Marina LED Aquarium Kit. It’s a bundled kit that comes with everything you need to get started, including a filter, LED lighting, and thermometer. It also has a low price tag compared to other tanks of similar size and material.
If you’re looking for something a bit bigger, then a 20 gallon long aquarium might be better for you. These tanks are taller and can accommodate larger fish than a regular 20 gallon tank. The best 20 gallon long tank on the market is the Aqueon Aquarium 20 Gallon Long. All you need is a powerful filter, a LED lighting system, and other essential equipment to set up your first tank.
