Are you looking to add a little aquatic life to your small space? A 5-gallon fish tank can be the perfect way to bring some personality and charm to your home or office.
However, with so many different types of freshwater fish available on the market, it can be difficult to know which ones are the best fit for your small aquarium.
We will explore some of the best fishes for 5-gallon freshwater tanks, providing you with a great starting point for creating a thriving and beautiful underwater world.
Introduction to 5 Gallon Tank Fishes
If you’re considering adding fish to your home, you may be wondering what kinds of fish can live in a 5-gallon tank. Luckily, there are plenty of options for small tanks that will thrive in a smaller environment.
It’s essential to consider the size of your tank when selecting which fish to keep. Freshwater fish require a certain amount of space to swim and thrive, with the general rule stating that you should have at least 5 inches of space for every inch of body length. So, for a 5-gallon tank, you will want to choose fish that are small in size and don’t require a lot of room.
There are plenty of small freshwater fish that can thrive in a 5-gallon tank, including Mollies, Dwarf Pea Puffers, Cory Catfish, and Endler’s Livebearers. These species are all unique and can provide a splash of color to your tank. Additionally, they are hardy and don’t require much upkeep, making them perfect for beginners.
When selecting which fish to keep in your 5-gallon tank, it’s essential to consider the compatibility and temperament of each species. Some fish may not do well together, while others may be aggressive or may require different water parameters. For instance, Betta fish are known for their aggressive behavior, making them unsuitable tank mates for most other fish.
Betta Fish: The Quintessential
The Betta fish is a popular and beloved choice for many aquarium enthusiasts, especially for those looking to set up a 5-gallon freshwater tank. With their beautiful and vibrant colors, Betta fish have become quintessential to the world of aquariums.

Furthermore, the Betta fish’s hearty appetite and low-maintenance diet allows for a variety of feeding options. They can be fed with dry food or live food, making it easy to keep their tank clean by removing uneaten food.
On the downside, Betta fish are also known for their territorial behavior in small tanks. Careful attention should be given to tankmates as they can become aggressive towards smaller, more timid fish.

One of the best things about guppies is that they come in so many different color and tail shape variations. Some have bright neon colors like electric blue or fiery red, while others have pastels or even transparent bodies. Their tails can range from simple fins to complex and ornate patterns that can take your breath away.
