Best freshwater fish for 20 gallon aquarium
If you are a beginner aquarist or looking to add some color and life to your home or office, a 20 gallon aquarium can be a great choice. This size provides enough space for a variety of freshwater fish that are both visually appealing and relatively easy to care for.
One of the best options for a 20 gallon aquarium is the Neon Tetra. These small, vibrant fish are known for their bright colors and peaceful nature. They thrive in a well-maintained tank with plenty of plants to mimic their natural habitat. Neon Tetras are also a schooling fish, so it’s best to keep them in groups of six or more to ensure their well-being.
Another excellent choice for a 20 gallon tank is the Dwarf Gourami. These fish have stunning, iridescent colors that will add a touch of elegance to your aquarium. Dwarf Gouramis are also peaceful and can coexist with other non-aggressive fish. They are known for their labyrinth organ, which allows them to breathe air from the surface, making them a unique addition to your tank.
If you’re looking for a centerpiece fish, consider the Angelfish. These graceful creatures have a large, triangular shape and long flowing fins that make them truly stand out in an aquarium. Angelfish can be kept in pairs or with other peaceful fish, but should be avoided if you have smaller species that may become their prey. It’s important to provide them with plenty of hiding places and a well-maintained tank to thrive.
Lastly, the Corydoras Catfish is a great option for a 20 gallon aquarium. These small, bottom-dwelling fish are not only adorable but also serve an important role in keeping the tank clean. Corydoras Catfish are social creatures and should be kept in groups of at least six. They prefer a sandy substrate and plenty of hiding spots to feel secure in their environment.
In conclusion, a 20 gallon aquarium offers a great opportunity to create a beautiful and vibrant underwater world. Whether you choose Neon Tetras, Dwarf Gouramis, Angelfish, or Corydoras Catfish, each of these species brings its own unique beauty and charm to your tank. Remember to properly research and provide their specific needs for a successful and thriving aquatic environment.
Guppies
Guppies are a popular choice for a 20-gallon freshwater aquarium due to their vibrant colors and peaceful nature. These small fish are known for their beautiful and elaborate tails, which come in a variety of patterns and colors. Guppies are easy to care for, making them suitable for beginner aquarists.
One of the reasons why guppies are a great option for a 20-gallon tank is their small size. Guppies typically grow to around 2 inches in length, allowing them to comfortably swim and explore in a tank of this size. They are also highly adaptable and can thrive in a wide range of water conditions, making them a hardy choice for beginner fishkeepers.
When setting up a 20-gallon aquarium for guppies, it is important to provide them with plenty of hiding spots and swimming space. Rocks, plants, and driftwood can be used to create a natural and stimulating environment for these active fish. It is also recommended to keep a ratio of one male to every two females to prevent excessive aggression.
Guppies are known for their breeding capabilities, so be prepared for the possibility of a growing population in your aquarium. If you do not want the guppies to breed, you can separate the males and females or introduce other fish species that may eat the fry. Regular water changes, proper filtration, and a balanced diet will help ensure the health and longevity of your guppies in a 20-gallon tank.
Neon tetras
Neon tetras are a popular choice for a 20 gallon freshwater aquarium due to their vibrant colors and peaceful nature. These small fish are known for their electric blue and red stripes that make them stand out in any tank.
One of the great things about neon tetras is that they are relatively easy to care for, making them suitable for beginners. They thrive in water with a slightly acidic pH and require a well-maintained tank with plenty of hiding spots and plants to replicate their natural environment.
Neon tetras are social fish and should be kept in groups of at least 6 to 8 individuals. They are peaceful and non-aggressive towards other fish, making them a great addition to a community tank. However, they should not be housed with larger, aggressive fish that may prey on them.
These fish have a small size of around 1.5 inches, which makes them suitable for a 20 gallon tank. They are active swimmers and provide a lively display with their shoaling behavior. Neon tetras can be fed a diet of high-quality flakes, pellets, and small live or frozen foods.

Dwarf Gouramis in a 20-Gallon Aquarium
Dwarf gouramis are popular choices for a 20-gallon freshwater aquarium due to their vibrant colors and peaceful nature. These small-sized fish, typically reaching a length of 2-3 inches, can thrive in a well-maintained tank with the appropriate water conditions.
One of the appealing aspects of dwarf gouramis is their beautiful coloration. They come in various shades, such as vibrant red, blue, and orange, adding a striking visual element to the aquarium. Their fins are long and flowing, enhancing their overall appearance. Whether you prefer a single dwarf gourami or a small group, these colorful fish can be a captivating addition to your tank.
Dwarf gouramis are known for their peaceful nature, making them suitable for community aquariums. However, it is important to note that male dwarf gouramis can be territorial towards other males, especially if multiple males are kept together in a small space. Therefore, it is recommended to keep only one male dwarf gourami in a 20-gallon tank. A single male can live peacefully with other peaceful species, such as tetras or small gouramis of a different species.
When it comes to tank set-up, dwarf gouramis appreciate a well-planted aquarium with plenty of hiding spots. The presence of live plants not only provides them with shelter but also helps to maintain water quality. This species thrives in water with a temperature range of 72-82°F (22-28°C) and a pH level between 6.0 and 7.5. They are also comfortable in moderately hard water conditions.
Overall, dwarf gouramis can be an excellent choice for a 20-gallon freshwater aquarium. With their vibrant colors and peaceful temperament, they can bring beauty and tranquility to your aquatic environment.
