How To Care For Pygmy Rasbora

The Pygmy Rasbora (Boraras brigittae) is a small, stunning species of freshwater fish known for its charming size and vibrant coloration. Native to the Southeast Asian waters, particularly Borneo and Sumatra, this diminutive fish has become a popular choice for aquarists seeking a peaceful, easy-to-care-for species for smaller tanks or aquascapes.

Growing to just 0.8 to 1 inch (2 to 2.5 cm) in length, the Pygmy Rasbora is one of the smallest species in the Rasbora family, making it ideal for nano aquariums or smaller setups. Despite its tiny size, it boasts a beautiful appearance, with a transparent body accented by a bright red coloration, particularly along the dorsal region and extending to the tail. This red coloration can be further enhanced in well-maintained aquariums with stable water conditions and proper care, making the Pygmy Rasbora a dazzling addition to any tank.

Pygmy Rasboras are social and active fish that thrive in schools. It is highly recommended to keep them in groups of at least 6 to 8 individuals to allow them to display their natural schooling behavior and reduce stress. These fish are peaceful and non-aggressive, making them excellent tank mates for other small, peaceful species like small tetras, microrasboras, and other small species of Danios. Their delicate size and peaceful nature also make them well-suited for a community tank with other non-aggressive species.

In terms of water conditions, the Pygmy Rasbora prefers slightly acidic to neutral water with a temperature range of 75°F to 82°F (24°C to 28°C) and a pH level between 6.0 and 7.5. They are sensitive to water quality, so regular water changes and good filtration are essential to maintaining a healthy environment. The addition of live plants and soft, slow-moving water can create an ideal habitat for these tiny fish, mimicking their natural environment in the wild.

As omnivores, Pygmy Rasboras have a varied diet that includes high-quality flake foods, micro pellets, and live or frozen foods such as brine shrimp, daphnia, and microworms. They are small feeders but will readily accept a wide range of foods. Providing a balanced diet helps them maintain their vibrant color and overall health.

Due to their size and active nature, Pygmy Rasboras are best kept in aquariums with soft substrates and plenty of plants or hiding spots to offer security and room to swim. They enjoy swimming in the mid to upper regions of the tank, darting through plants or small spaces in search of food.

With proper care, including a stable tank environment, regular water changes, and a varied diet, the Pygmy Rasbora can live for 3 to 5 years or more in captivity. Their small size, peaceful nature, and stunning color make them a perfect addition to a nano aquarium or planted tank.

In summary, the Pygmy Rasbora is a beautiful, hardy, and social fish that offers both visual appeal and peaceful temperament to freshwater aquariums. Its small size, vibrant coloration, and active swimming behavior make it a popular choice among aquarists, particularly for those with smaller or well-planted tanks.
