What To Look For When Buying A 20 Gallon Fish Tank ?


With the 20 gallon tank’s size, it is fairly easy to plan set up a design or theme, just as it is quite versatile in terms of fish stocking.

With such potential in an average tank, how do you choose the right one for you? Here are some of the factors to consider when looking for the perfect 20 gallon tank for you.

Choosing The Right Dimensions

With a fish tank that is as versatile as the 20 gallon tank, there are sure to be some variations. The first one and probably the most common among the three is the 20 gallon long tank. With dimensions of 30 x 12 x 12, it is often chosen to be a reef tank because of its orientation. With loads of space for decorations, a theme that is meant to be wide can be highlighted with this 20 gallon tank.

Up next is the 20 gallon high tank, which is measured at 24 x 12 x 16. Its tall stand makes it beautiful for designs with a number of layers, for example, taller live plants. Lastly, there is the rarer 20 gallon EXTRA high tank, sitting at 20 x 10 x 24.

Choosing the right dimensions is important for two reasons. First, considering the direction and design you might want to see in the tank. Will it fit your whole theme, will it highlight the theme’s strengths? Second is the placement. The right variation of the 20 gallon tank will have you setting your worries aside, in terms of safety and stability of the tank.

Choosing The Right Placement

The dimensions of the tank are directly related to its placement. No one would want a tank to be a hindrance in a certain spot, not with the fragile parts and materials that the tanks come with. The 20 gallon tank shines in this area because of the delicate balance it presents, it is big enough to store multiple fishes and more ambitious set-ups, but yet small enough to not cause a massive placement problem.

The 20 gallon tank is a beautiful addition in any room, and it provides a certain kind of therapeutic view for everyone who chances upon it. As a longtime tank enthusiast, I have found that one of the most important factors to consider is the stand that holds the tank.

With quite a large amount of water in it, aside from the weight that is brought about by the materials, it is made of, alongside the fishes and the décor, the 20 gallon tank will prove to need a sturdier stand than those used for 15 gallon tanks.

While it will surely take up a small space in any room, it will not pose much a problem than the bigger tanks. Just make sure that it is placed on a spot where the set-up’s needed amount of heat, cold, and exposure is met.

Choosing The Right Materials

There are a number of pros and cons when it comes to choosing the perfect material when choosing your 20 gallon tank, and they are not to be overlooked.

The traditional 20 gallon tank is made of glass. Hobbyists from all over the world have known this variation for the longest time. It is durable, as it is not much affected by scratches. Its sturdy material results in less yellowing in the long run, however, it is also quite heavy and will be in need of reliable support.

There is also the acrylic 20 gallon tank, which has become more and more popular as time went by. The acrylic 20 gallon tank is visibly clearer and quite easy to clean. It is also easy to move around because of its lighter weight. However, it does not have the same scratch resistance as provided by the glass tank.

Both are safe for the tank and your little fishies, and both have decorations and equipment that supports the material the aquarium is made of. Choosing the best one for you relies on the placing spot you have, as well as the aesthetic visuals that you are planning for.

Ultimately, it relies on what kind of direction you would want to take in. Because of its size, its versatility can be seen in the set-up it creates, be it a community tank, a breeding tank, or even a hospital tank. Be sure to have a clear picture of your plans in your mind as you choose the right 20 gallon tank variation.

The Right Price For You

After evaluating every factor from dimensions, placing, and the material, it is now time to think about the price. One great aspect of the 20 gallon tank is that it is an affordable tank, due to its popularity and size. The glass tanks are generally cheaper than its acrylic counterparts, but only in a smaller margin, unlike in the bigger tanks where variation costs may vary vastly.

As most of the 20 gallon tanks are sold as a package, complete with the lighting equipment, alongside the filters, heaters, coolers, and substrate, it can be a lot cheaper than other average-sized tanks. It also helps that it makes for an easier set-up process since all the equipment is already compatible with the tank’s material.

Choosing the right price also relies on another factor: the warranty. The existence of a product warranty is a show of the brand’s guarantee, and it can affect the pricing of the product itself. Will you opt for a one-time, cheaper buy for your tank or will you want to secure it for the long term? These are questions you should ask yourself before choosing the right tank for you.

It is as well a great beginner fish tank for newcomers because of its affordability and size.
