1. MarineLand Contour Glass Aquarium Kit

Pros

  • Moonlight LED light
  • Easy access canopy
  • Sleek design
  • Built-in filtration system

Cons

  • Light may not be bright enough

If you plan to set up your small aquarium in a very cramped space, the MarineLand Contour Glass Aquarium Kit is an option you can consider.

Measuring only 9.5 x 10 x 10 inches in dimensions, this tank is one of the smallest on this list and can fit into the tightest corners of your house with ease. Along with this, the three-gallon capacity is enough to keep one or two small fish without any issues.

Also, all of these features are perfectly designed to work together and fit perfectly to provide a sleek and continuous design for this tank.

One of our favorite features of this tank kit was the LED lighting system. It offers a range of options, such as a daylight and moonlight setting that uses bright white LED lights in the day and blue LEDs at night to mimic natural lighting.

It helps your fish maintain a healthy and natural routine similar to that in the wild. Setting up the light is also easy as it perfectly fits the easy-access sliding canopy.

Another thing you won’t have to worry about is water filtration with this tank kit. That is because MarineLand has built-in an advanced filtration system that combines mechanical, chemical, and biological filtration to keep your tank water crystal clear.

Also, each kit comes with an adjustable filter pump, so you can always manage the water flow rate to match your pet’s requirements.

That being said, one thing you will have to keep in mind with this tiny aquarium is that all the accessories and systems are built into one side of the tank. So, you can only see into the tank from three sides which makes it better suited for placement against a wall.

What’s most impressive is that Fluval manages to fit these systems and much more into a thin sidebar in the tank. Built out of aluminum, the sheet slides out and manages to perfectly fit in all of the wirings and act as a base for the overhead lighting rod.

However, while the tank itself looks pretty modern and sleek with the aluminum finish, it is one of the larger options on this list. Measuring 20.5 L x 11.6 W x 7.5 H inches in dimensions, this tank might not be the best choice if you plan on keeping it in a very cramped space.

Things To Consider While Choosing a Nano Aquarium

Here’s a list of some things you should consider when looking for a nano aquarium:

– Aquarium Material

Best Nano Aquarium for your home fish tank setupThe aquarium material is an essential factor you should consider when purchasing a new aquarium. It can affect various factors ranging from the overall clarity of your tank to its crack resistance and more.

Currently, most nano tanks available on the market are either made from acrylic materials or out of glass.

Acrylic tanks are often much better when it comes to impact resistance, making them a lot easier to carry and transport. While they can handle more substantial impacts, these tanks are prone to more minor scratches and corrosion. So, they often tend to lose clarity and appeal in the long run.

On the other hand, tanks made out of glass can resist scratches and corrosion much more effectively. Thanks to this, they are an excellent choice for long-term use of saltwater tanks and won’t yellow over time.

However, these tanks need to be handled with care as significant impacts can be shattering.

– Filtration Capability

One of the most critical factors of any tank setup is the filtration system. That is because tank water tends to build up in toxic materials due to fish waste, which can lead to deterioration in your fish’s overall ecosystem and health.

So, it is essential to have a sufficiently robust filter connected to your tank to clear out these waste materials.

Many nano tank kits available on the market come with in-built or additional filters right out of the box. These filters are often designed specifically for the tank and often provide three-stage filtration, sufficient for most tanks.

That being said, be sure to check out what filter is provided and if it will be powerful enough for your pets and requirements to avoid any mishaps.

– Lighting System

The lighting system is one thing that immensely adds to the appeal of any tank setup. Turning on an array of lights that bring out the color in your pets and plants can not only liven up the tank but also improve their overall routine. With this in mind, many aquarium companies are providing lighting systems within their tank kits.

That being said, all lighting systems are different, and it is important to find the right one for you. So, when buying a new tank, try to look for factors such as the type of lights used, timer functionalities, as well as how powerful the lights are.

All these factors can make the difference between a good lighting system that livens up your tank and one that doesn’t get the job done.

– Design

When it comes to nano tanks, the overall design and aesthetic appeal are pretty essential to consider before making a purchase. That is because most nano tanks are used for indoor spaces such as the living room or bedroom and are meant to decorate and liven up your ambience.

To help improve the overall appeal, many tanks are built in unique and eye-catching designs. For example, some tanks are designed in unique globe shapes, while others come with black walls to create a modern and sleek look.

So, when buying a new nano tank, be sure to check out your requirements and look for one that suits your home.

FAQ

Let’s discuss a few frequently asked questions related to nano aquariums:

– How Big Should a Nano Tank Be?

While there is no hard and fast rule as to the size of a nano tank, it is commonly assumed that a nano tank should be at least three gallons in capacity. It is important because if you have a tank smaller than this, it will be challenging to maintain a community of fish safely and instead, you would be limited to a maximum of one or two fish.

– Are Nano Tanks Easy To Keep?

No. While nano tanks may look easy to maintain, this is not the case. Smaller tanks are often more difficult to maintain as compared to larger tanks. It is primarily due to the lower water volume, making the overall environment much more prone to problems such as toxicity or changes in temperature.

– Do You Need Filter for Nano Tanks?

Yes, even though nano tanks contain much less water, keeping them regularly filtered is very important. Filtration is essential for all tank setups as no matter the size, waste produced by your pets and plants will lead to toxic and murky water if left alone.

Also, it is often more important to continuously filter a nano tank as any unwanted substances can quickly pollute the whole tank due to their smaller size.

– Can You Keep a Clam in a Nano Tank?

Yes, you can most definitely keep a clam in your nano tank without having to worry about its health. The only problem with this is that most clams will eventually outgrow smaller tanks, at which point you will have to relocate your pet!

– How Often Do You Have To Clean a Nano Tank?

While the exact frequency of cleaning is dependent on the type and number of inhabitants your tank has, a good rule of thumb is to clean your tank bi-weekly. It ensures that you are able to maintain a healthy environment and get rid of things such as uneaten food, debris, and any toxic waste that your filter wasn’t able to clean.

– How Many Fish Can Be in a Nano Reef Tank?

Nano tanks tend to be very small, due to which you won’t be able to keep more than a few fish in them. For example, a 12-gallon micro aquarium should only hold about two to three fish at a time. If your tank is even smaller, such as five gallons, it is advisable to stick to one or at max two small species of fish to ensure the environment stays clean and healthy.

– What Temperature Should My Nano Tank Be?

Ideally, your nano aquarium should stay around 78 F for most fish species. However, if your tank houses tropical species like zebra fish, guppies, tiger barb, etc., you should increase the temperature to 80 F. Luckily, it does not take long to warm the water in nano fish tanks. 

– Which Tank Sizes Qualify as a Nano Tank?

According to many aquarists, a nano tank is usually a glass tank with a standard volume of around 14 gallons. Additionally, it should be under 2 x 1 x 1 cubic feet in dimensions to be considered as a nano aquarium
