How do You Stock a 5-Gallon Fish Tank?

From its specifications, it is clear that a 5-gallon fish tank is very small in size compared to other tanks known so far. This means that when setting up your tank, you need to ask yourself the following simple questions:

  • How many fish can be housed in a 5-gallon aquarium?
  • What are the best species of tank fish for your 5-gallon aquarium?
  • What are the best 5-gallon aquarium fish combinations?

Generally, a 5-gallon tank has a small capacity so you are only limited to whatever you can manage to accommodate there.

When stocking your 5-gallon aquarium with fish, you need to follow the rule of thumb. This rule states that you should only fit an inch of tank fish per gallon in a given aquarium. You shouldn’t get carried away with this rule because there are other species of fish that cannot thrive best in such a confined tank space.

Most importantly, you should focus on how big your fish will get when housed in a 5-gallon tank. Just stock your tank with enough fish that will stay comfortably without competing for the limited resources within their surroundings.

Also, remember that your tank can house other aquatic animals such as snails and shrimps as well as plants. In this case, ensure that there is enough space for every living thing that you will add to your 5-gallon tank.

Once you know the correct number of fish that you can house in your tank, the next step should be to choose the species of fish for your aquarium. Here is a list of tropical fish that are suitable for a 5-gallon aquarium:

  • Betta Fish
  • Honey Gourami
  • White Cloud Mountain Minnow
  • Various
  • Micro Rasboras
  • Dwarf Frog
  • Dwarf Puffer
  • Least Killifish
  • Clown Killifish
  • Dwarf Crayfish
  • Rosy Loach
  • Endler’s Livebearer
  • Cherry Red Shrimp
  • Crystal Red Shrimp
  • Ghost Shrimp
  • Nerite Snail

Basically, these are the types of fish and aquatic creatures that you can accommodate in your 5-gallon tank comfortably. To be on the safe side, you should add your fish gradually while monitoring the constant water parameters as well as how your fish is adapting to the new environment.

Can You Put Plants in a 5-Gallon Nano Tank?

The answer is yes. Plants are part and parcel of any aquarium. Whether they are artificial or live, plants play a critical role in aquascaping and balancing tank conditions for the fish to survive.

A planted 5-gallon tank not only looks good and appealing to the eye, but it also becomes the best habitat for aquatic animals. Plants are known to keep the tank water quality in check as well as preventing spiking.

For that reason, you should as well plant a few plants in your tank to provide your fish with the hiding places improve aeration and even act as a source of food for some species of fish. Some of the recommended plants that you can add to your aquarium include:

  • Java Moss
  • Anubias
  • Java Fern.

You may choose to add one of these plants or include a combination of them to create some variations.

How do you Maintain a 5-Gallon Aquarium?

Fish tanks need regular maintenance to keep them in good working conditions. Also, proper maintenance of your tank exposes your fish to the right conditions for their well-being. This is the same case with a 5-gallon tank.

Below are a few tips that can help you maintain your aquarium:

  • Make sure that your tank is cycled before adding fish
  • Make a habit of testing and monitoring tank water parameters
  • Ensure that you perform tank water changes on a regular basis
  • Do enough research on the species of fish you want to keep in your tank before purchasing it
  • Avoid providing your fish with excess food because it may go to waste and contaminate the tank
  • Manage light around and in your aquarium

With all these helpful tips at your fingertips, nothing should prevent you from keeping the conditions in and around your 5-gallon aquarium favorable for your fish.

What Substrate can you use in a 5-Gallon Tank?

If your 5-gallon aquarium is a planted type then you must use a substrate for the plants to grow well. All plants in the tank have different forms of the root system. Some of them are simple while others are a little bit complicated.

Despite the complexity, every type of roots on a plant plays a key role in taking in essential nutrients. That’s why plants stay alive and grow healthy in any environment. For the aquatic plants in the aquarium to grow well and “stand up” firmly, they must be provided with the right substrate.

There are numerous substrates that you can use in your 5-gallon tank. Most of them have different chemical compounds. Apart from that, most of these substrates have different characteristics.

Here are a few examples of substrates that you can use in your planted tank:

  • Aquarium Gravel
  • Aquarium Sand (Coral sand, Marble Chippings, Marbles, Soil-like Substrate)

Even though all substrates play a critical role in providing tank plants with nutrients and stability, the best option for your 5-gallon tank is the soil-like substrates. This is because they can be mixed and matched with a little amount of other substrates for better results.


A 5-gallon fish tank kit with all necessary features is a great choice, especially if you are a beginner. As stated earlier, this tank is one of the smallest but with the right knowledge about it, you can really make the best use of it as you advance your fish-keeping skills.
