When beginners to aquarium care begin to think about adding an aquarium to their home a common concern is space. A 5 gallon fish tank is a fantastic solution to this.
They will often come in dimensions of around 16" x 8" x 10" and can fit on any desktop or surface. Yet still they are big enough to be fitted with a filter and heater safely which most fish need to thrive and have happy lives.
Fish bring a different sense of life to the atmosphere of a room. There is nothing better than taking in the beauty of fish swimming peacefully.
We have picked five of the best 5 gallon fish tanks. We also created a buyer’s guide that tells you what to search for when looking for the ideal aquarium.

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 a fish bowls. Fish bowls 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 fish keeping - which is why we would recommend upgrading from that fish bowl 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 you aquarium will be made from.
Acrylic Fish Tanks
The advantages of acrylic fish tanks are:
- Super clear viewing
- Lighter than glass
- Can be moulded 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:
- Less 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 is 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 is requires its own specialist aquarium stand.
It is even more critical that you find a tank that fully satisfies the needs of your fishes. Here are five possible options for fish aquariums for you to consider.
