If you have been on the hunt for a new aquarium, or should we say a little fishbowl, you might be interested in the Tetra Waterfall Globe Aquarium. Now, this is by no means an aquarium you would get for any large amount of fish or any bigger purpose.

It is something small, something that fits onto your desk or night table. It makes for a good starter tank for kids as well. While it is not the largest aquarium out there by far, it can fit a couple of little fish such as tetra fish just fine.

This is our Tetra Waterfall Globe aquarium review, we aim to tell you what this tank has to offer in terms of features along with our opinion of it to help you decide if it’s the right tank option for you.

Don’t get it wrong, if you are looking for a nice aquarium for a few fish, this is not the way to go. This thing is small and really only designed for Tetra fish and other such minuscule creatures.

Now, with that being said, the Tetra Globe Aquarium does have some neat features. If you have kids, it might be a good starting point for pets (we have covered kids’ tanks separately here).


Ok, so this whole aquarium, or really the bowl, is a total of 1.8 gallons in size. That is under 8 liters of water. If you did not know, some fish like Betta fish require around 3 gallons of space at least, which is also true for others like goldfish.

If you are looking for a good Betta tank then we have covered a detailed buying guide over at this article, that covers some good and suitable tank options.

In other words, this thing is really only ideal for 2 or 3 small tetra fish. With that being said, the small size of this aquarium does make it convenient because as long as you have a power cord or AC outlet nearby, it can fit pretty much anywhere you want it to fit. While it is not large on the inside, it is definitely a space saver.


This particular aquarium does come with a little Tetra Whisper cartridge filtration unit to keep the water clean. Now, the filter itself is fairly durable and should last for quite some time.

The motor is fairly strong and proven to come with a fair bit of longevity. Also, the Whisper filtration unit is specially designed to be quiet and make little noise, which is always nice.

Now, the filtration unit itself is not all that efficient, to be honest. It comes with a cartridge that included biological and mechanical filtration. The cartridges are easy enough to change, which is good because they don’t last for too long.

Also, the filtration unit does not come with any chemical filtration, which is indeed a bit of an issue. All in all, the filtration system included here is good enough for this small tank, but definitely not for anything else.

The Tetra Globe Aquarium comes with a small light built into the hood. The light is nothing special, although having one is better than not having any light at all. It’s just a simple little bulb that provides your fish and plants with some daytime illumination.

It does not have a timer, nor does it have different colors. It is really just a simple light that you can turn on and off with the included power switch. The light is good enough for general illumination, but don’t expect it to help your plants grow.


One neat feature here that your kids might like is the little waterfall that the Tetra Globe Aquarium comes with. The filtration unit spits the water back out into the tank through a small waterfall. It looks really nice, and it does help to aerate the water a little bit, but past this aesthetic appeal, there is really not much to it.

Some people like the gurgling noise which it produces, while other people are annoyed by it. It is really a matter of personal preference more than anything else.


The other aspect of the Tetra Globe Aquarium that needs mentioning is how it is built using real glass. This is a good thing because it does make the viewing experience nice. It’s a very clear glass bowl that is difficult to scratch.

With that being said, just don’t drop the thing because, unlike acrylic, it will almost definitely shatter. The black base which this thing comes with is somewhat cool, because it provides a bit of elevation, contrast, and it just looks nice.

  • Scratch-resistant.
  • Looks nice.
  • Decent filtration unit for this tank.
  • Decent light included.
  • Easy to maintain in all ways.
  • Has a cool waterfall.
  • Does not use up much space.
  • Great for children.
  • Glass can smash easily.
  • Not suitable for anything larger.
  • No chemical filtration.


All in all, if you just want something really small for yourself or your kids, the Tetra Globe Aquarium is a nice option to go with, mostly for visual appeal. It’s easy to maintain, it can last for quite some time, and it definitely looks nice too. Just don’t expect to fit any large or numerous fish in this thing as it is very small.
