Advantages of a 20-gallon fish tank
There are many advantages to buying a 20-gallon tank versus any smaller size. It is a great size for any size of home. You can pick a great local spot and have it as the focal point of any room! All you need to do is have ample space around the fish tank so it doesn’t get knocked over. It will need the proper cleaning and maintenance, so take this into consideration when deciding where to place it.
This size is large enough to host a number of different species at one time. All you need to make sure is that they are either saltwater or all freshwater, and you will be good to go! This is also big enough to house a number of real plants if you should decide to go that route instead of the fake plants that most come with. Real plants and certain fish can make a tank run cleaner for a longer period of time, so this a viable option to consider.
You do not have to clean a 20-gallon tank as often as a smaller capacity tank. This means much more time to enjoy the environment you have created! While cleaning is not that hard of a job, it does consume some time. And it is required! There are some things you can do to minimize the number of times you have to clean, including certain plants and certain species of fish that will work together to keep the tank cleaner!
You will get less food waste because you can have more fish for the available space. Wasted food can cause a lot of problems for a fish tank, including causing the filter to need to be changed more often, causing the water to need to be changed more often, and causing the condition of the fish to deteriorate. The more often that you have the clean the tank, the more likely the fish will stay stressed out and not enjoy the environment you have made them, possibly even becoming hostile with them.
You can have some fish that are not suited well to the smaller tanks. This means even more options and more variety that you have available to you! There are all kinds of exotic fish that are available to us, especially if you choose to go with a saltwater tank. This also means that you can get more of one kind of fish, even if they can be territorial as the bigger tank will give ample space for them to have their own territory.
Features to consider before you buy a 20-gallon fish tank
If this is your first time buying a 20-gallon fish tank, there are some key features you should look for when buying one. Do not be afraid of all the options out there. That is why we made this list! However, if you choose to go with another choice, keep some important features in mind.
Glass or acrylic is the best choice. Glass is the industry standard. However, acrylic is becoming more popular. Both of these are quality choices for any fish tank. Almost all of our picks are made of solid glass and will last a lifetime, save one. The SeaClear Acrylic Combo set is made purely of acrylic. But don’t let this steer you away. It is both stronger and lighter than its glass counterparts.
The average glass, 20-gallon fish tank weighs in at 225 pounds when filled with water. This is no small weight, so make sure you have adequate support. If you look at our Editor’s Choice, the GloFish Aquarium Kit, it weighs just over 34 pounds. However, if you look at the SeaClear Acrylic Combo set, it comes in at only 20 pounds!
24 x 12 x 20 inches is the standard size for a 20-gallon fish tank. There are other sizes available in the custom market. You could get almost any size and any shape you would like built, but all of our choices fit the standard size. The Tetra ColorFusion Aquarium, our third choice, comes in one of the industry standards, 27.88 x 16.13 x 20.38 inches. While one of our choices, the Aequen Aquarium, comes in at 30.25 x 12.5 x 12.75 inches, which is slightly wider than we normally see.
There are many accessories, including filters, lids, LED lights, plants, backgrounds, heaters, gravel, food, hoods, seasonal decorations, and alternating fish.
There are so many options out there that are available for purchase that you could never get tired of changing out what is inside your tank.
Our Editor’s Choice, the GloFish Aquarium
, comes with the highest number of accessories when purchased. However, this should not stop you from searching for extra accessories!
The square design is what you typically get with a 20-gallon fish tank. Some custom companies will build special shapes. All of our picks come in the standard shape, but some are slightly wider, while some are slightly taller. They will all still hold the same amount of water when filled with water. You can add more tanks to your collection instead of trying to get a custom design made as this is often cheaper and more efficient in the long term than going for the custom-made tank.
