Having pets is great, especially when you have a nice aquarium full of beautiful fish.

Fishkeeping is a popular hobby, and a big part of it is because there are so many different fish to choose from and so many different aquascapes to create.

With that being said, before you can begin choosing your fish, you first need to have the right tank, along with the right lights, filters, and other accessories too.

Today, we will look at an all-in-one kit to get you started.

Tetra Aquarium 20 Gallon Fish Tank Kit


The Tetra Aquarium 20 Gallon Fish Tank Kit is a very reasonably priced fish tank kit that costs just over $100, which is a fair price considering what comes with it.

It’s a fish tank that looks quite decent and comes with the required components to keep your fish happy and healthy.

Who is This Product For?

The Tetra Aquarium 20 Gallon Fish Tank Kit is for people who want a moderate-sized aquarium for a few fish but not so large that you don’t have space for it.

This is also a good tank for beginners, especially for those who want a nice all-in-one kit and don’t want to shop for individual components and accessories. On that same note, it’s ideal for people working with a limited budget.

What’s Included?

When you purchase the Tetra Aquarium 20 Gallon Fish Tank Kit, there are quite a few things that come included with it. Here is what you get with your purchase.

  • 20-gallon glass aquarium
  • Aquarium hood
  • LED lighting system
  • Tetra Whisper Filter
  • Filter media
  • A 100-watt aquarium heater
  • An artificial boxwood plant mat
  • Four artificial plants

Overview of Features

First off, as the name says, this is a 20-gallon tank. The tank’s dimensions are  27.88 x 16.13 x 20.38 inches, which enough for quite a few fish yet compact enough to fit in most spaces.

This is a glass aquarium that is very good looking and highly resistant to scratching; however, it is a bit heavy. However, let’s keep in mind that it is made in the USA, a big bonus.

The Tetra Aquarium 20 Gallon Fish Tank Kit features a very basic LED lighting system built into the included hood. It is designed to mimic natural sunlight, and we think that it does a good job.

Moreover, the Tetra Aquarium 20 Gallon Fish Tank Kit comes with an efficient and powerful Tetra Whisper 20 filter that can easily filter up to 3 times the tank’s water volume per hour. It also uses the 3 major forms of water filtration.

You may also like the high-quality 100-watt aquarium heater included here that should keep your tank at a steady 76 degrees. This makes it perfect for all sorts of tropical fish.

The fact that it comes with artificial plants is a bonus. Artificial plants may not look the best, but at least they don’t require maintenance.

Not the most durable components


If the Tetra Aquarium 20 Gallon Fish Tank Kit is too large for you, or maybe the components don’t seem durable enough if you have a bit of extra to invest, consider something like the MarineLand Contour Glass Aquarium Kit.

On the other hand, if you need something more extensive, say a 50-gallon tank, and you have the cash to spare, something like the SeaClear Acrylic Aquarium Combo Set might be worth checking out.


As you can see, the Tetra Aquarium 20 Gallon Fish Tank Kit is an excellent option to consider for several reasons.

It’s large enough for a good number of fish, yet small enough to fit in most spaces. It’s exceptionally durable; it comes with everything you need to take care of your fish, and it comes in at a relatively reasonable price. It’s an option we recommend checking out if you need a new aquarium.
