Rasboras Profile

Rasboras are small, peaceful freshwater fish, native to Southeast Asia. Known for their bright colors and schooling nature, they are ideal for community aquariums. Adaptable and easy to care for, rasboras add a dynamic and harmonious presence, making them a favorite among both novice and experienced aquarists.

Rasboras are perfect for beginners and experienced aquarists alike. Their peaceful temperament makes them compatible with a wide range of tank mates, and they rarely show aggression. Because of their small size and low bioload, they’re a great choice for planted tanks or aquascapes where balance and subtle beauty matter. Their schooling behaviour creates a natural and cohesive look, especially when swimming in unison. Many species, like the Harlequin and Chili Rasbora, also feature vibrant red, orange, or copper tones that enhance visual appeal without overwhelming the tank.

Rasboras may be hardy, but they do best in stable, well-maintained tanks with soft, slightly acidic water—conditions similar to their natural habitat. They can become shy or stressed if kept alone or in too small a group, so a proper school size is essential. Fast or aggressive tank mates should be avoided, as rasboras can be easily outcompeted during feeding. Additionally, their small mouths mean they need appropriately sized food such as micro pellets, crushed flakes, or live baby brine shrimp.

Rasboras are small, active schooling fish that bring movement and subtle beauty to freshwater aquariums. Native to Southeast Asia, they are known for their shimmering colours, peaceful nature, and ease of care. Most species grow no larger than 5 cm, making them ideal for nano and community tanks. Rasboras tend to occupy the upper to midwater levels, adding dynamic activity to areas other fish may ignore. They are also highly social and display their best colouration and behaviour when kept in groups of six or more.
