Best fish tanks and aquarium kits to buy in 2020

Fish are one of the most interesting pets to have at home. Both adults and children love the movement of colorful fish as they swim around in their tanks. In addition to providing a serene, relaxing view, a fish tank or aquarium acts as an excellent decoration and gives an elegant, sophisticated look to the room. That brings us to the million-dollar question. Which are the best starter fish tanks and aquarium kits to get for your home?

In this article, we will look at some of the best fish tanks and aquarium kits available in the market. We will primarily look at two categories of fish tanks – those with a capacity of 5 gallons or less and those with a capacity of over 5 gallons. The small tanks make an excellent desktop decoration you’re your office, bedroom or dorm, while the larger models are perfect for your living room. Moreover, the options we list are suitable for all social fish breeds, though the low capacity models would work well for loners such as betta fish as well.

Based on the space available and preference, you can then pick the most suitable option for your need. So snorkel up, and read on!

If cleaning the fish tank is something you hate, then you should look at getting yourself a self-cleaning fish tank.

And if you do not have enough space for a full blown fish tank, why not consider getting a wall-mounted fish tank?

How to pick the best fish tank or aquarium?

With so many options available in the market, picking the best aquarium starter kit can often be a challenging task. After all, a fish tank is more than just a container for your pet fish.
The first thing you need to consider before picking an aquarium is the overall size range you are looking at. In our opinion, any fish-tank with a capacity of less than 3 gallons would not be a great choice, unless you are looking something for a corner on your table. Fish tanks with a capacity of 3 to 5 gallon are excellent options for desktops, corner tables, offices and dorm rooms, while bigger tanks are most suitable for their dedicated tables or stands.

Once you have finalized the size range, you can consider the following additional factors before deciding on the most suitable option:

  • Construction material of the tank
  • Shape and Size of the tank
  • Pump and Filtration system of the aquarium
  • LED Lighting in the tank
  • Additional accessories and considerations

Construction Material of the tank

The construction material of the tank is probably the most important criteria to consider. Modern day fish tanks are made of one of the three materials – glass, acrylic and plastic.

  • Glass Tanks: Among tanks with a capacity of up to 20 gallons, glass is the most popular building material. Glass tanks are generally heavier, relatively rigid and less expensive than acrylic tanks. Glass also retain the clarity over time and are more scratch-proof when compared to acrylic or plastic tanks.
  • Acrylic Tanks: Acrylic tanks have become increasingly popular in past few years. Acrylic is lighter and more moldable, so you can have uniquely shaped tanks. And because acrylic has almost same refraction index as water, you tend to get a better view in the tank. Acrylic is, however, more scratchable and has a tendency of yellowing over a period of time so would require more care.
  • Plastic Tanks: Plastic tanks are the cheapest of the three. Plastic is also moldable and lightweight but is not scratch resistant and as durable as glass or acrylic tanks. You should generally avoid plastic tanks.

If you do not have a weight of the tank as a factor (or if you are looking for a 100+ gallon tank!), you should consider opting for glass tanks. While acrylic tanks provide the best non-rectangular shapes, modern aquariums with glass tanks also come in nice, curved shapes.

Shape and Size of the tank

As discussed above, the shape and size of the tank is another important factor to consider. You should pick a shape and size for which you can provide a stable base and do not have to move the tank frequently.
Rectangular flat and tall-boy shapes are perfect for countertops and tabletops. Smart curved shapes make an excellent addition to the corner tables and restricted viewing angles. 3D tanks such as Fluval Edge Aquarium with LED Light are most suitable for stable 360-degree locations within your living or bed room.
Keep these things in mind while picking the best shape and size for your aquarium.

Pump and Filtration system of the aquarium

In order to ensure that your tank is clean and your fish have access to fresh water, you need an aquarium with an excellent filtration system. While you can always get an alternative filter for your tank, it is generally more suitable to get a tank which comes with a filtration system with a quiet air circulation pump incorporated.

In addition to checking the presence of a filtration system, check it efficacy by looking at the number of stages it supports. Most high-end aquariums come with multi-stage filtration systems (mechanical, chemical and biological filtration) that combine conditioning and filtering to create a fresh water source.

Moreover, check how easy it is to access the filter for cleaning. Smart fish tanks such as the Marina LED Aquarium Kit provide easily removable clip-on filters that can be replaced without much fuss. Some other models even have their filters in a separate unit as the tank for easy accessibility and maintenance.

LED Lighting in the tank

The variety and efficiency of LED lighting system in the tank is another factor to consider. Most tanks provide either an inbuilt or canopy-type single-light LED lighting system which can be turned on and off through a switch.
Some fish tanks such as the Marineland ML90609 Portrait Aquarium Kit provide a combination of lighting – white LEDs to simulate sunlight and blue LEDs to simulate moonlight glow. Such aquariums are our favorites, though even in single lighting tanks, you can always opt for external lighting plates and surfaces as per your needs.

Additional factors and considerations

In addition to the four factors discussed above, there are a couple of other factors that can make a purchase more attractive than others.
One such factor is the accessories that come with the aquarium kit. Small aquariums generally do not come with additional items, but Most 5+ gallon starter kits come with items that can get you started on building your aquarium in no time. This may include artificial decoration plants, feed supply and caring guide. Check out the accessories that come with the aquarium before picking the best option. Off-course, depending upon the type of the fish, you may have to adjust the accessories that you are going to use. As an example, you may not want to use artificial plants with a betta fish, as they may harm its fins.
Another important factor to check out is the warranty and service support provided by the manufacturer. Most top brands such as Hagen (Fluval, Marina) and Tetra provide multi-year warranties with their products. Aqueon even provides a lifetime warranty against manufacturing defects. On the other hand, cheaper brands such as KollerCraft only provide a 90-day warranty. A word of advice: to avail the full warranty support, always look for an authorized seller and register your aquarium kit with the manufacturer.

Keep these other small considerations in mind while picking the best options for your needs.
