3. Marineland Portrait Glass LED Aquarium Kit

The Marineland fish tank has a three-stage filter for great water conditions.

Dimension: 11.8 x 11.6 x 17 inches

Size: 5 gallons

The Marineland aquarium is of a portrait orientation – this is good for those that do not have much desk/tabletop space as the tank is not as wide as other 5-gallon fish tanks.

The fish tank has some great design finishing touches such as the modern black frame.

The design is enhanced further with a hidden back compartment that houses the included advanced 3 stage filter. (plus there is enough room for you to squeeze in a small heater)

Bright LED lighting is included on a hinged-over hanging frame and makes part of the well-thought-out design of the tank. The lighting has two settings, white and blue (night mode), that could support some easy-care live plants.


  • Great for first-time fish owners
  • 3-stage filtration system for great water quality
  • check-circleHidden back compartment keeps filter and heater out of view 


  • Portrait design means fish have less horizontal swim  space 
  • Lid is a little fiddly


4. Tetra Crescent Aquarium Kit

Energy efficiency and hidden LED lights are cool features offered by the Tetra.

Dimension: 16.6 x 11.2 x 13.2 inches

Size: 5 gallons

Energy efficiency and lighting are at the helm of the Tetra Crescent fish tank. Several LED lights are hidden within the design of this aquarium. A mechanical filter neatly fits on the back of the tank and works quietly to keep water conditions optimal.

This aquarium kit is ideal for beginners.

The Tetra aquarium comes with a kit that makes it easy for beginners to start. Ultra Activated carbon is incorporated for more efficient removal of odors and discoloration. The size and shape of this tank make it a great fish tank for a betta fish.


  • LED lighting is bright
  • Great size and shape


  • Lid is quite flimsy
  • Acrylic tank is not for everyone

The 14.4-inch length of this tank is bigger than most 5-gallon fish tanks. We also rate this tank as the best betta fish tank.


  • Great quality and stylish product
  • Advanced filtration system included
  • LED lights included which can support live plants
  • Fully rotatable center cube for better positioning


  • Lighting can only be used with the filter turned on


Fish Tank Buyer’s Guide

Features of a Fish Tank


The average 5-gallon fish tank comes equipped with a filtration system, artificial lighting and some include a heater. A top, which is separate from the central part of the compartment, is typically where the lighting system is housed.

The filtration system is a vital component of the 5-gallon aquarium. This is what separates them from fish bowls.

Fishbowls are not healthy places to bring up fish as without a filter the water quickly becomes dirty and full of toxins from fish waste. Great water quality is the staple of good fishkeeping – which is why we would recommend upgrading from that fishbowl to an aquarium like these 5-gallon ones below.

Acrylic Versus Glass Fish Tanks

When shopping around for your first tank you will probably see a variety of designs and a variety of prices – and you may think “what is the difference?”. One main difference is the materials that your aquarium will be made from.

Acrylic Fish Tanks

The advantages of acrylic fish tanks are:

  • Super clear viewing
  • Lighter than glass
  • Can be molded into cool shapes

The disadvantages of acrylic fish tanks are:

  • Prone to scratches
  • Porous so can absorb chemicals
  • Can yellow over time
  • Generally more expensive

Glass Fish Tanks

The advantages of glass fish tanks are:

  • More scratch resistant
  • Won’t ‘yellow’ over time
  • Non-porous (so don’t absorb chemicals)
  • Generally cheaper than acrylic tanks

The disadvantages of glass fish tanks are:

  • Heavier
  • Fewer design shapes available

In general, as long as you are aware of the points above you will be able to make a sound choice. We believe a glass tank such as Fluval Spec V tank is the best value as that material holds up over time. It doesn’t discolor and it is resistant to scratches as you clean it.


There is also the option of selecting aquariums according to classifications. The most common of these types of characterizations are:

  • The Freshwater aquarium, which is the most popular – especially for beginners
  • The Marine or Saltwater aquariums, which are more work to maintain thereby, less popular to beginners.
  • The Brackish Water aquarium, which combines elements present in both Freshwater and Marine tanks.

With so many options on the market, it may be challenging for you to decide which 5-gallon fish tank is the best choice. You want something that is bright enough to accentuate the room, yet not so huge that it requires its own specialist aquarium stand.

It is even more critical that you find the best tank that fully satisfies the needs of your fish. Here are five possible options for fish aquariums for you to consider.

The Best Fish Tank From Our Reviews

The Fluval Chi is our best 5-gallon fish tank. With its eye-catching design, advanced 3 stage filter, and LED Lighting is the clear winner among the five fish tanks.

There is a high quality that is expected with Fluval products and the Fluval Chi delivers. The fully rotatable center cube for better positioning is a great feature especially for fish lovers living in small spaces.
