How To Care For Chili Rasbora

The Chili Rasbora (Boraras brigittae) is a tiny but stunning species of freshwater fish, often considered one of the most beautiful small fish in the aquarium hobby. Native to Southeast Asia, particularly in Indonesia, the Chili Rasbora is highly prized for its vibrant colors, especially its bright red body, which is accentuated by subtle iridescent markings. This species is also known by other common names like the Fire Rasbora due to its striking, fiery coloration.

Typically, the Chili Rasbora grows to an average length of 0.8 to 1 inch (2 to 2.5 cm), making it an excellent choice for nano aquariums or smaller community setups. Their tiny size, paired with their vibrant red color, makes them a captivating addition to any aquarium, especially when kept in groups. A prominent feature of this species is the neon-like blue stripe that runs along their body, giving them a beautiful contrast and a shimmering effect under the light.

Chili Rasboras are peaceful, schooling fish and thrive in small groups of at least 6 to 10 individuals, but they can often be kept in slightly larger groups for optimal social behavior. These fish are typically non-aggressive and work well with other small, non-aggressive species like neons, tetras, dwarf corydoras, and other rasboras. However, due to their small size, it's best to avoid housing them with larger, more aggressive species that could potentially harm them.

In terms of water conditions, the Chili Rasbora prefers slightly acidic to neutral water with a temperature range of 72°F to 80°F (22°C to 27°C) and a pH range of 5.0 to 7.5. They do well in well-maintained aquariums with clean, filtered water and thrive in soft water. Providing a well-planted tank with plenty of hiding spots, such as caves or dense vegetation, helps them feel secure and encourages natural behavior. Additionally, they appreciate aquariums with gentle filtration to mimic their natural habitat in slow-moving streams.

The Chili Rasbora is an omnivore, feeding on a variety of foods including high-quality flake food, micro pellets, and live or frozen foods such as infusoria, daphnia, and brine shrimp. Due to their small mouths, it's essential to provide appropriately sized food for them to eat, and feeding them small amounts several times a day is ideal for their health.

These fish are relatively low-maintenance but do require stable water conditions and a balanced diet. With proper care, the Chili Rasbora can live for 3 to 5 years or more in captivity. Due to their striking appearance, peaceful nature, and small size, they are ideal for nano aquariums, planted tanks, and peaceful community setups.

In conclusion, the Chili Rasbora is a vibrant and charming fish that is perfect for aquarium hobbyists looking to add a splash of color to their tank. Their small size, peaceful temperament, and dazzling coloration make them a great choice for beginners and experienced aquarists alike. With proper care, they can live happily in your aquarium and add a beautiful touch to your underwater world.
