Best Fish Tanks – Reviews
Fish tanks come in many different shapes and sizes. They can include additional equipment, such as a filter or LED light, or you can purchase just a plain rectangular container.
To give you a broader perspective of which fish tank is the best for you, we will cover the top six fish tanks on the market.
Fluval Vista Aquarium Kit 16 Gallons

With a panoramic design that attracts attention, the Fluval Vista Aquarium Kit 16 Gallons is one of the best starter aquariums. It has everything you need to set up a fish tank.
The bowed shape of the front glass will appeal to hobbyists who have an eye for aesthetics. It is bound to stand out in your room wherever you place it. Accompanied with the Soft-start LED light that mimics natural daylight and doesn’t upset your fish, the Fluval Vista 16 makes an eye-catching element of your interior design.
Apart from its attractive look, this fish tank comes with Aquaclear 30 filter, a high-quality fish tank filter with a 3-stage filtration system. In other words, the Aquaclear 30 filters the water mechanically, biologically, and chemically, making sure that the habitat for your fish is clean.
What’s more, the hang-on filter is ideal for fish tanks up to 30 gallons in size. Thus, Aquaclear 30 will be more than enough to keep your 16-gallon tank clear. It requires cleaning every two weeks, so maintenance doesn’t feel like a chore.
Additionally, the Fluval Vista 16 includes a 100w heater and an outside thermometer. This lets you maintain the most optimal temperature for your fish. You will also get a water conditioner and biological additive which will enable you to add fish immediately.
Fish food is included as well, so you won’t have to think about your fish’s first meal.
The drawback of this fish tank is that it does not include plants or decorations. You will have to purchase these separately if you wish to add an aesthetic touch to your fish tank.

A cheaper alternative for beginners is the Tetra Aquarium 20 Gallon Fish Tank Kit. Like the Fluval Vista 16, this 20-gallon tank has everything a fish tank needs to get you up and going right away. It has a typical rectangular shape, scratch-resistant glass, and a slightly bigger size than the Fluval Vista 16.
The Tetra Aquarium 20 comes with an energy-saving LED hood that creates a daytime effect. This ensures your fish have sufficient light, even if you decide to keep your aquarium in a place where your fish don’t receive enough natural daylight.
Should you want to put live plants in your aquarium, this 6000K LED light will support plants that don’t need a lot of light, like java fern. For light-needy plants, you will have to purchase additional lighting.
The Tetra Whisper 20 filter that comes with this fish tank kit runs quietly and is powerful enough to provide a strong water flow.
Furthermore, the Tetra Whisper 20 has a 3-stage filtration system that clears the water of particles, toxins, and ammonia (which is extremely bad for your fish). The fish tank kit also includes the Tetra Mini UL heater, enabling you to regulate the water temperature.
Should you opt for the Tetra Aquarium 20, you won’t have to think about fish food or water conditioners, at least in the first few days of your new fishkeeping hobby. The fish tank kit includes Tropical Min fish food and AquaSafe water conditioner.

With its portrait design, this elegant aquarium will fit anywhere in your interior and make a captivating ornament for your home.
The Marineland Portrait Glass tank includes an LED with two modes, which adds to its overall stylish appearance.
You can switch between the modes since one replicates the daylight shimmer, while the other creates an alluring moonlight glow. This enables you to change the appearance of your aquarium to fit the mood of your room.

The filter is located at the rear of the fish tank, so you always have a clear view of your tiny water pets.

This is the simplest and the cheapest option you will come across. The COLIBROX Aqua Aquarium is a simple rectangular glass aquarium that is ready for customization.
It’s up to you to choose the filter, heater, thermometer, plants, water conditioners, LED, and everything else you want. The COLIBROX Aqua Aquarium allows you to configure your fish tank precisely the way you want it.
On the other hand, this fish tank may not be suitable for fishkeeping beginners. You would have to research every component a fish tank needs, which can feel like a grind if you are just taking up the hobby.
20 L x 12 W x 10 H
Finding a fish tank that you like the best is only half of the work. Buying a fish tank that won’t benefit your fish is just a waste of time and money.
So, you have to determine which fish tank is the best fit for your needs. We compiled a few factors that you need to keep in mind when buying a fish tank.
Types of Fish Tanks
Depending on what they contain when you buy them, fish tanks can be divided into three categories:
Basic Glass Tank
The COLIBROX Aqua Aquarium that we reviewed earlier is an example of a basic glass tank. This type of fish tank includes only the glass container itself. You don’t get any additional equipment. This gives you the freedom to organize your aquarium precisely the way you want.
But purchasing each part of fish tank equipment separately can be costly. For this reason, we don’t recommend basic glass tanks to fishkeeping novices but rather to experienced hobbyists who want to create a custom aquarium.
Every beginner aquarist should consider purchasing an aquarium kit first. These all-in-one fish tanks are usually designed for new aquarists.
The equipment these kits include is carefully selected with the size of the fish tank in mind. Therefore, you will not have to bother buying a filter, heater, thermometer, plants, LED light, fish food, aquarium net, water conditioners, and other fishkeeping accessories.
However, carefully check what each fish tank kit includes. Some kits may not include all the necessary equipment. For example, none of the fish tank kits we reviewed include an ammonia test kit, and testing the water for ammonia is essential to your fish’s life.
Also, watch out for cheap equipment that is sold as part of the kit. Some companies may sell a fully operating fish tank, but the filter’s quality may be poor considering the equipment’s overall price. So, choose wisely.
Some aquariums are sold with fixed equipment, meaning you can’t change the filter location or any other part of the equipment. Like aquarium kits, systematized aquariums may also be suitable for beginners since the manufacturer has already placed the equipment where it should be, and they know the best.
Still, if you ever wish to change or upgrade a part of your aquarium equipment, this can be a struggle. Therefore, should you want to buy this aquarium, please meet all your fishkeeping preferences.
Size and Species of Fish You Want to Keep
This is the most crucial factor when buying a fish tank. You are essentially buying a new habitat for your fish. You want to make sure that your fish can live a healthy life in their fish tank.
The size and number of fish you intend to keep are essential when choosing the right fish tank. Ideally, a large aquarium is always better. But it can also be costly.
Whatever size of fish tank you want to buy, you have to consider the fish size. Just to be safe, you should follow the “one inch per two gallons” rule. For example, a fish that is three inches long will need six gallons of water.
Bear in mind that fish grow as they mature, so this ratio may change with time. To avoid this, do thorough research on the growth patterns of fish you want to keep.
As for fish species, there are over 33.000 of them. Maybe you have already chosen one or more species you wish to keep. Fortunately, you only have to know two basic categories.
Freshwater (Tropical) Fish
As a beginner, it will be easier for you to maintain a freshwater aquarium. Goldfish are suitable for a start, but they can grow very large and produce a lot of waste, making your aquarium maintenance a little more complicated.
Also, you don’t want to mix bettas with any other species as they can be aggressive. The species that go well together are domestic platies, neon tetras, and swordtails.
Saltwater (Marine) Fish
If you don’t mind engaging more with your fishkeeping hobby, maybe saltwater fish are for you. Dottybacks, for example, need a lot of hiding spots.
Firefish are generally friendly with other species. Tangs are aggressive only towards their own species but friendly towards other fish, so you should keep only one of these.
In any case, you should consult an expert to see which fish species are best for your fish tank and vice versa.
Weight of the Tank
Fish tanks up to 15 gallons can be placed on a shelf or a desk. However, fish tanks larger than this are very heavy when filled. You should have a separate firm stand for it to avoid the risk of any breakage.
Your aquarium needs to have proper filtration to ensure a sufficient water flow for your fish. Most aquarium kits include a filter that is just the right size for the fish tank it comes with.
Still, if you want to buy a filter separately, there is one rule you should follow: The filter should allow the entire volume of fish tank water to pass through your filter four times within one hour.
Also, it is never a mistake to go for a filter designed for larger fish tanks.
You want to ensure that your fish tank has LED lighting, and here’s why. LED lighting consumes a small amount of energy and has a long-lasting life. It generates no heat, which means that it won’t affect the water temperature.
Also, it is easily programmable, so you can set different colors or light intensities for your aquarium. Another great thing is that most aquarium kits come with LED lighting.
You are buying a fish tank not only for your fish but for your home as well. Choosing the right fish tank design is an essential factor.
There is nothing worse than buying an aquarium that just feels awkward in your living room. Fish tanks come in many different designs. Apart from the classic rectangular shape, there are tower tanks, round tanks, bowfront tanks, and square tanks.
Furthermore, there are fish tanks you can mount on a wall! So, you have options from which to choose.
Finally, look at the construction of the aquarium. This more or less comes down to whether you want a glass or acrylic tank. Glass looks great, and it is scratch-resistant.
However, it features less impact resistance than acrylic and is much heavier too. This is a tradeoff to think about.
You could write a whole book on this matter, but essentially:
1. Vacuum out the bottom about once per week to remove waste.
2. Clean and maintain your filter.
3. Scrub algae off the tank walls.
4. Perform weekly water changes.
Your aquarium water may be cloudy because:
– It has not been properly cycled yet
– There could be dissolved organic compounds in the water
– There could be a buildup of waste
– Sand or gravel could be emitting small particles into the water
– The filter may not be working efficiently
– You might be seeing algae
No, this is an absolute myth.
Generally speaking, it will take between 3 and 5 weeks for a tank to cycle.
Algae feed off ammonia, and it likes lots of natural sunlight, both leading causes of algae bloom in aquariums.
Depending on the type of fish you wish to keep, your fish tank may need a heater. Saltwater fish need heat, while not all freshwater fish do. You have to know the optimal temperature for each species and determine whether your fish tank needs a heater or not.
However, the other important factor is your room temperature. If your home has a good heating system, perhaps you don’t need to buy a heater. Still, you should always have a thermometer for your fish tank and regularly check to ensure the water temperature is suitable for your fish.
The answer to this question may be different for you and for the fish. You will most likely go for a fish tank that is most pleasing to the eye and for which you already have an ideal place in your home in mind.
But consider the fact that your fish needs oxygen to breathe. The greater the surface area, the more oxygen your fish will have.
Also, rounded or bowfront tanks can be disorienting for your fish as their perception of the outside world is distorted. If you care about your fish only and don’t care about the aesthetics, consider buying a rectangular fish tank.
For novices in fishkeeping, we recommend glass fish tanks. They are cheap, resistant to scratching, and the glass will remain clear after ages of use.
But they can break upon impact, so you need to be very careful where you keep your glass tank. Aesthetic-wise, the shapes in which glass fish tanks come lack variety.
However, plastic (acrylic) fish tanks are much lighter than glass tanks, and they won’t break as easily. They come in different sizes, so there is a greater chance that you will find the best match for your home.
The bad thing about acrylic tanks is that they are easily scratched and can yellow with age.
You should never overstock your fish tank. Your fish need enough room to move freely. Otherwise, they will get stressed out and start acting aggressively towards each other.
Also, there are health issues that your fish may suffer. Fish produce waste that contains ammonia, a toxic chemical that can be dangerous to them.
If there is too much ammonia in your fish tank, this can lead to ammonia poisoning. Your fish can get ammonia burns on their skin and most likely die if you don’t provide them with immediate treatment.
Yes, but be careful. Tap water in most community water systems contains chlorine. This chemical compound is detrimental to your fish’s health. But this doesn’t mean that you can’t use tap water to fill your fish tank.
This is when a dechlorinator – a water conditioner – comes into play. You can treat your tap water with this and ensure that the water for your fish will be healthy. Just remember to read the product label to learn about the exact dosage.
Fishkeeping seems like a simple hobby, but there are many things you have to consider in reality. Choosing the appropriate fish tank is essential for the quality of life of your fish.
Aquarium kits are the best options for starters as they usually include all the components that a fish tank needs. Alternatively, if you are confident enough, you can buy a fish tank alone and equip it how you like.
Though some aquarium designs and sizes may be attractive at first glance, we highly advise you to always consider the fish you will keep in that aquarium. Is there be enough room for them? Do they have everything they need?
Maybe you need to purchase an additional heater if you want to keep heat-needy fish. You need to consider all this so that both you and your fish are satisfied with their new home.
