One of the most popular rasboras for a 20 gallon tank is the Harlequin Rasbora (Trigonostigma heteromorpha).

Corydoras
Corydoras are a popular choice for community tanks, especially in a 20 gallon tank setup. These small catfish are known for their peaceful nature and their ability to get along with a variety of other fish species. They are also easy to care for, making them perfect for beginner fish keepers.
One of the main advantages of keeping Corydoras in a community tank is their scavenging behavior. They are bottom-dwelling fish that constantly sift through the substrate in search of food. Not only does this help keep the tank clean, but it also adds an interesting dynamic to the tank as they dart around the bottom in search of tasty morsels.
When it comes to tankmates, Corydoras are compatible with a wide range of fish species. They are generally peaceful and can coexist with other peaceful community fish such as tetras, gouramis, rasboras, and livebearers. However, it’s important to avoid keeping them with fin-nipping or aggressive species, as Corydoras are easily stressed.
In addition to their compatibility with other fish, Corydoras are also a visually appealing addition to a community tank. They come in a variety of colors and patterns, with some of the most popular species including the Bronze Corydoras, Panda Corydoras, and Peppered Corydoras. Their unique appearance and playful nature make them a joy to watch as they explore their surroundings.
In conclusion, Corydoras are an excellent choice for a 20 gallon community tank. Their peaceful nature, scavenging behavior, and compatibility with other fish species make them a great addition to any community setup. Whether you’re a beginner hobbyist or an experienced fish keeper, Corydoras are sure to bring life and vibrancy to your tank.
