Having an aquarium in your home or office can bring a sense of tranquility and beauty to any space. If you’re looking for a small and compact aquarium, a 5-gallon fish tank is an excellent choice.
It’s perfect for beginners and enthusiasts who want to keep a small community of fish or a couple of colorful bettas.
In this guide, we will explore the best 5-gallon fish tank and equipment available in 2024 and provide step-by-step instructions on how to set up your tank.
Essential Components for Setting Up Your 5 Gallon Fish Tank
Setting up the best 5-gallon fish tank requires careful consideration and the right equipment. Here’s a breakdown of everything you’ll need to create a successful and thriving aquatic environment.
Fish Tank
Choose a 5-gallon tank made of either glass or acrylic. Both materials have their advantages, with glass providing better clarity and scratch-resistance, while acrylic tanks are lightweight and less prone to breakage.

- Schooling or Solitary Fish
Since a 5-gallon tank is relatively small, it’s best to choose small fish species or those that have minimal activity levels. Avoid fish that grow large or are highly active swimmers, as they may feel cramped and stressed in a small space.
Different fish species have specific water parameter requirements in terms of temperature, pH level, and water hardness.
Ensure that the fish you choose are compatible with the water conditions you can maintain in your tank.
Conduct research on the ideal water parameters for your desired fish species to make sure they align with what you can provide.
Consider the compatibility of the fish you want to stock. Some fish species are known to be aggressive or territorial, which can lead to conflict in a small tank. Look for peaceful and community-oriented fish that can coexist harmoniously.
Some fish species prefer to live in groups, while others are solitary. If you choose schooling fish, ensure that your tank can accommodate a small school of them comfortably.
Solitary fish can be a good option for a 5-gallon tank, as long as they are compatible with the other tank inhabitants.
Popular fish choices for a 5-gallon tank include:
- Betta fish: Known for their vibrant colors, bettas are solitary fish that can thrive in a 5-gallon tank. Ensure that only one male betta is housed in the tank to avoid aggression.
- Tetras: Some species of tetras, such as neon tetras or ember tetras, are suitable for a small tank. They are schooling fish, so a small group of 4-6 individuals can create a lively display.
- Guppies: Colorful and active, guppies are small fish that can thrive in a 5-gallon tank. Consider keeping a small group of males or a mix of males and females.
Choosing the best 5 gallon tank
