Red Line Rasbora

The Red Line Rasbora (Rasbora pauciperforata) is a small freshwater fish native to the clear streams and rivers of Southeast Asia, particularly in Indonesia. This species is renowned for its distinctive appearance, featuring a striking red line running along its body that contrasts beautifully with its iridescent scales. Adult specimens typically reach a maximum size of about 5 cm, making them ideal for community aquariums and nano tanks.

In terms of behavior, the Red Line Rasbora is a peaceful and social fish, often found in small schools in the wild. They thrive in well-planted aquariums, where they can exhibit their natural schooling behavior and explore their environment. Their calm demeanor makes them compatible with a wide range of tank mates, including other small, non-aggressive species. Observing a school of these fish darting through the water is a captivating sight that adds life and movement to any aquarium setup.

Their natural habitat consists of slow-moving waters with dense vegetation, which provides shelter and breeding grounds. The Red Line Rasbora prefers slightly acidic to neutral pH levels and requires clean, well-oxygenated waters to thrive. In the wild, they feed on small insects, zooplankton, and plant matter, which influences their dietary needs in captivity.

Due to their charming appearance and peaceful nature, Red Line Rasboras are popular among aquarists and are often sought after for use in community tanks. Ensuring proper care and environmental conditions will help these fish flourish and display their best colors.

When caring for Red Line Rasboras, it is crucial to maintain stable water parameters. The ideal temperature range is between 24°C and 28°C, with a pH level between 6.0 and 7.5. Regular water changes and good filtration are essential to keep the water clean and oxygenated.

Feeding should consist of high-quality flake food, micro-pellets, and occasional live or frozen foods such as daphnia or brine shrimp to offer a balanced diet. It is advisable to feed them small amounts multiple times a day rather than one large feeding to ensure they receive adequate nutrition without polluting the water.

In terms of compatibility, Red Line Rasboras do well in community tanks with other small, non-aggressive species. They thrive in groups of at least six individuals, as they are shoaling fish and feel more secure in numbers. Acclimation should be done slowly, ideally over a few hours, to prevent shock from sudden temperature or water parameter changes. Quarantine new fish for at least two weeks before introducing them to the main tank to prevent the spread of disease.

Red Line Rasboras are suitable for shipping due to their hardy nature. They should be packed in breathable bags with adequate oxygenation and minimal water to prevent stress during transport. A packing density of around 1-2 fish per liter is recommended to ensure their well-being. They are sensitive to temperature fluctuations, so maintaining a stable temperature between 24°C and 28°C during transit is crucial. These fish are not currently listed under CITES, making them easier to export.
