Mosquito rasbora
Introduction
The Mosquito rasbora (Boraras brigittae), also known as the Chili rasbora, is a captivating freshwater fish cherished by aquarists for its vibrant red coloration and peaceful demeanor. Despite its diminutive size, this species adds a striking visual appeal to any aquarium. Ideal for nano tanks, the Mosquito rasbora is relatively easy to care for, making it suitable for both beginner and intermediate fishkeepers.
Care and Environment
Providing optimal care for the Mosquito rasbora involves replicating its natural habitat to ensure health and vitality.
What is the minimum tank size for a Mosquito rasbora?
A minimum tank size of 12 liters is recommended for a single Mosquito rasbora. However, as they are shoaling fish, it's best to keep them in groups, necessitating a larger tank.
What are the ideal water parameters for Mosquito rasboras?
Maintain a temperature between 20–28°C, a pH range of 4.0–7.0, and water hardness of 18–179 ppm. Consistent water quality is crucial, as they are sensitive to fluctuations.
How should the aquarium be set up for Mosquito rasboras?
Use a soft, sandy substrate with ample vegetation, including floating plants to diffuse light. Incorporate driftwood and leaf litter to mimic their natural environment and provide hiding spots.
Filtration should be gentle to avoid strong currents, aligning with their preference for slow-moving waters. Regular water changes are essential to maintain water quality. For feeding, offer a varied diet of high-quality flake foods, micro pellets, and small live or frozen foods like daphnia or brine shrimp. Ensure food particles are appropriately sized for their small mouths.
Origin and Habitat
Native to the blackwater streams and peat swamps of South West Borneo, Indonesia, the Mosquito rasbora thrives in slow-moving, tannin-rich waters. These environments are characterized by dense vegetation, submerged roots, and leaf litter, creating a dimly lit habitat with soft, acidic water conditions. The substrate typically consists of sand covered with decomposing leaves and twigs, providing ample hiding spots and a natural food source through microfauna.
Temperament and Compatibility
Mosquito rasboras are peaceful, shoaling fish that exhibit their best behavior and coloration when kept in groups of at least six to ten individuals. They are timid and may become stressed if housed with larger or more aggressive species.
What are suitable tank mates for Mosquito rasboras?
Ideal companions include other small, peaceful species such as Ember tetras, Pygmy corydoras, and small shrimp species. Avoid housing them with larger or aggressive fish to prevent stress and potential predation.
How do Mosquito rasboras behave in a community tank?
In a well-planted community tank with appropriate tank mates, they will actively swim and display their vibrant colors. However, they may become reclusive if the environment is too bright or lacks sufficient hiding spots.
Interesting Facts
The Mosquito rasbora's striking red coloration intensifies during breeding periods, with males displaying more vivid hues to attract females. They are egg scatterers, depositing eggs among fine-leaved plants. In the wild, their diet consists of small insects, crustaceans, and zooplankton, highlighting their role as micropredators. Despite their delicate appearance, they can live up to 4–8 years with proper care, offering aquarists a long-term, rewarding experience.
