The Best 5-Gallon Fish Tanks Under $150


Whether you want a freshwater aquarium or saltwater, a 5-gallon fish tank is a great place to start. 

There is something utterly mesmerizing about watching fish swim circles in their glass aquarium. If you love watching fish as much as I do, then a 5-gallon tank (if you have space) is the way to go!

Fish Tank Features

To make things easier for novice aquarists, you can get a 5-gallon fish tank, which is perfect for a small space. Some fish tank features you need to consider are items such as:

  •  LED lighting.
  • Built-in filtration.
  • A crystal clear view of the fish.

In some cases, a kit will come with an adjustable pump or even a small container of fish food! Aquarium tank kits are a stress-free way to put together your first tank.

Put a couple of pieces together, place in your fish (after you acclimate them!), and let your stress slip away as you watch them swim around their new home.

What do you need for a small fish tank? 

Small aquariums tend to be the first choice of fish tanks for many new keepers but don't be fooled; a 5-gallon tank is still a lot of work! Many kits come with an internal filter and a basic setup. However, you will need to get substrate, aquarium plants, and high-quality decorations for your fish to hide and play around in.

Even if you have a great filter, you will still need to do periodic water changes. Having a small fishbowl handy for water changes will be helpful, especially if your tank gets really dirty. You need to remove the fish to clean it.

Some of the fish that are ideal for this tank include:

Just remember that a 5-gallon tank cannot hold as many fish as larger tanks can. According to Aqueon, you do not want to overcrowd your tank with too many small fish. Try to keep it to one fish per 2 inches. Also, make sure you give it a few days before you put your fish into a newly set up tank. Usually, 2-3 days after setup is best.

The last thing you want to watch out for is mixing docile fish and aggressive fish in the same tank. Try to keep the temperaments of your fish the same to avoid any conflict, and try not to mix tropical fish and non-tropical fish since they like the water at different temperatures.

Here are ten 5-gallon tanks under $150 for your Betta fish or whatever fish you wish!
