Are you looking for a 5-gallon tank, but you don’t know which fish tank to choose? Then you have come to the right place. In this article, we will examine which fish tank kits that contain 5-gallon tanks are best for you.

5-gallon tanks are perfect if you require small tanks that do not take too much space and are also not expensive. 5-gallon fish tank kits are some of the cheapest aquarium options out there. But why get a fish tank kit rather than buying parts separately?

Fish tank kits offer you great flexibility and practicality. When you buy a fish tank separately, you then have to look for a filter, heater, LED lighting and other important parts that are necessary to start a tank. With fish tank kits, you do not need to bother with those choices, because they come included in the kit.

However, if you want to give your tank a better filtration, please check which filter I recommend for small aquariums.

Fish tank kits for 5-gallon aquariums are a popular choice between the inexperienced fish tank owners and those people who have never owned one. They offer you the convenience of having everything ready to go out of the box, you just need to set it up.

But don’t worry, you will not need to spend much time setting it up, because most of these kits come with instructions included.

What Fish Can You Keep in 5 Gallon Aquarium?


What Fish Can You Keep in 5 Gallon Aquarium?

There is plenty of choice when it comes to picking the right fish for your 5-gallon tank. Really a wide variety of fish can live in such an environment.

If you want to have just one fish in your 5-gallon tank, the betta fish is the best choice for you. Also known as the Siamese fighting fish, this fish is so mesmerizing to look at that so many owners decide to keep it on its own. You will have to consider the temperament of the betta fish, and that is an aggressive one.

If you want to have a community tank, then there’s loads of other smaller fish that would make an excellent choice. Dwarf puffers come to mind – they are small, but active fish and you can keep more of them together. All different sorts of gobies are also perfect – bumblebee gobies, round gobies. Celestial pearl danios would also make an excellent addition, with their appealing look and friendly character. Consider adding some shrimp and snails to make it a lively place. Don’t overstock it, though. It is better to have fewer fish rather than more to ensure quality of life.

How to Keep a 5 Gallon Fish Tank Clean?

You will have to do regular maintenance, or else the quality of the water conditions will start to deteriorate and your fish will not be happy and healthy. You need to check the water temperature, the water alkalinity and how clean the water is on a regular basis.

Also do water cycling changes once or twice a week, because this will ensure that the water will be clean at all times. If there is some algae or debris building up in your tank, then you might want to consider getting some snails to get rid of it. Alternatively, consider using chemicals, but more natural options should be preferred, such as snails. If you do have to use chemicals, then try to use as little of them as possible.

Also clean the glass and the substrate regularly. You can clean the substrate by vacuuming, and clean the glass where dirt might accumulate. If you have live plants, clean them before you put them into the water.

Of course you can, and it is sometimes even better to have live plants rather than plastic ones. Live plants will make the tank a more natural habitat, which will help the fish to adjust quicker, but they will also provide the water with some important chemical elements.

One thing that you do need to keep in mind with live plants is that they can be quite sensitive sometimes, so make sure that the water is optimal for the plants. This is why often beginners are recommended to get plastic plants rather than live plants.
