Cherryspot Rasbora Care Guide

The Cherryspot Rasbora, scientifically known as Rasbora rubrodorsalis, is a small and vibrant freshwater fish that adds a splash of color and activity to any aquarium. Native to the peat swamp forests and blackwater streams of Southeast Asia, particularly in Thailand and Malaysia, this species is prized for its striking appearance and peaceful behavior, making it an excellent candidate for community tanks with other peaceful and similarly sized fish.

Rasbora rubrodorsalis is characterized by its slender body and the distinctive cherry-red spot located near the dorsal fin, from which it gets its common name. The rest of the body is typically a translucent gold or tan color, with subtle iridescent hues that catch the light as they move. This species is relatively small, making it a perfect choice for nano tanks or larger community setups seeking a touch of dynamic color.

Creating an ideal habitat for the Cherryspot Rasbora involves mimicking the soft, acidic conditions of their natural environment. The aquarium should be well-planted with both floating and submerged vegetation to provide ample hiding spots and replicate the densely vegetated waters of their habitat. Driftwood, leaf litter, and a dark substrate can also help simulate the tannin-stained waters they are accustomed to, providing a comfortable and stress-reducing environment.

The diet of Rasbora rubrodorsalis is omnivorous, consisting mainly of small invertebrates and zooplankton in the wild. In captivity, they thrive on a varied diet that includes high-quality flake foods, micro pellets, and live or frozen foods such as daphnia, brine shrimp, and micro worms. Offering a balanced diet is crucial for maintaining their health, energy levels, and vibrant coloration.

Breeding Cherryspot Rasboras can be a challenge but is certainly achievable with attention to water conditions and diet. Like many small rasboras, they are egg scatterers, releasing their eggs among dense vegetation where the adults are less likely to find and consume them. Providing a breeding tank with soft, acidic water and plenty of plant cover can encourage spawning behavior. The fry are tiny and require infusoria or other very small foods until they are large enough to accept standard fry foods.

Caring for Rasbora rubrodorsalis involves maintaining clean water with regular water changes and careful monitoring of water parameters to ensure a stable environment. Their peaceful and schooling nature makes them ideal for community tanks, where they can be kept with other non-aggressive species that do not outcompete them for food or space.

In summary, the Cherryspot Rasbora, Rasbora rubrodorsalis, offers a unique combination of beauty, peaceful behavior, and relatively straightforward care requirements, making it an attractive addition to the freshwater aquarium. While their care does require attention to their specific environmental and dietary needs, the rewards of keeping Cherryspot Rasboras include the enjoyment of their lively schooling behavior and the visual appeal they bring to the aquatic setting.
