No Heater

This Marineland Aquarium does not come with a heater, it does have a space for it, but you will have to purchase it separately if you need one.

The cherry on top, it also has a sleek transparent lid which allows viewing from multiple dimensions.

Limitations

There are a couple of things that could have been improved design-wise, which I have mentioned ahead.

Plastic Lid

Although the plastic lid is transparent, it would have been better if the lid was made of glass. That would not only have given one look to the entire piece but also allow a similar experience from the sides and the top.

LED Light

The LED Light’s design could have been better; it does not blend in with the tank and just stands out as an extra piece. GloFish could have given more attention to the LED Light Design. LED Design of the other two Fish Tanks is much better.

These drawbacks are not deal breakers, just something to consider if you want your aquarium to look like one piece.

HOW TO CHOOSE THE BEST SMALL FISH TANK

Choosing a Fish Tank is not as easy as it looks. You have to consider various things and ask yourself whether you are ready to give a clean and beautiful home to fishes or not.

They do not require a lot of attention, but you have to make sure that their tank is filled with clean water and fed on time. These are the few questions you should ask yourself before getting yourself into this aquarium hobby.

And if the answer is Yes, you should go ahead and invest in one of the fish tanks I have mentioned above. You also have to consider where you will put the fish tank because if you do not have enough space for it, you will want to consider purchasing small tanks. I have added some of the best small fish tanks and chose them after vigorous research.

Following are some of the essential factors I considered while selecting these small Fish Tanks. Before finalizing your purchase, take a look at these factors mentioned in the buying guide below. These will assist you through your purchase. For quick digestion of the buying guide, you can count on the infographic below as well.

Size

The very first thing you have to consider is the size of the tank. Based on the space you have available for an aquarium, choose the size accordingly. Every tank comes with the dimensions in inches, so wherever you want to place it, measure the space beforehand. Along with size, you also have to consider the weight of the aquarium. Apart from the tank weight, the ornaments, filter, LED Lights, and water also weighs a lot.

Material

Another vital thing to consider is the material of the tank. There are two types of most common materials in Fish Tanks: Glass and Acrylic. While Glass is a material that gives a high-end classy look. While Acrylic is excellent for beginners because it is 15 times more durable.

Glass body allows a more immersive experience and a clear view. However, Acrylic also allows a great view, but it is not as clear as Glass. But at the end of the day, it is your choice whether you want a clearer view or a more durable option.

Filter

To ensure that the water is clean at all times, Fish Tanks comes with a filter that takes dirty water from the tank, clean it, and then sends it back to the tank. Most of the small Fish Tanks already comes with a built-in filter. I chose the ones which come with a built-in filter to save you from the hassle. The built-in filters also provide water circulation, which helps to oxygenate the water.

LED Lighting

Lighting is also something you need to consider. It is not only great because it highlights the beautiful colors of fishes, allows you to have a beautiful experience in the dark. But it is also suitable for fishes and aquarium plants. LED Lights come mainly in two different colors: White and Blue. LED Lighting is a preferred aquarium lighting option, not only because they use less energy, but they also last longer and are safe for fishes. White LED Lights are similar to natural daylight, and Blue LED Lights gives an effect of moonlight.

Top

Most of the small Aquariums come with a top that stops the water from evaporating or fishes to accidentally jump out of the tank. The top can be made of plastic or glass, which also protects the water from getting dirty. The top part either slides or has a hole on top to help feed the fishes with ease.

Design

The fish tank design is also fundamental because they also function as a décor item other than being your therapy spot. I only compiled small fish tanks with a beautiful design that allows an immersive and wholesome viewing experience.

Durability

You obviously want your fish tank to be strong and durable so that it lasts a long time and stays your fish’s beautiful home for a long time. Although the glass Aquariums I mentioned in the list are durable. However, Acrylic Aquariums are the top choice if durability is your primary concern.

WRAPPING IT ALL UP!

To conclude, I must add that fish tanks are, without a doubt, a great hobby. Although hobbies do give comfort and relaxation, aquarium keeping tops all other hobbies in terms of peace. There is something about water and fishes that eases your mind. Fish Tanks mentioned in the list above are all suitable for small spaces. They are packed with excellent features, making them the best in comparison to others in the market.
