Emerald Dwarf Rasbora (Bio-Secured Bred)

The Emerald Dwarf Rasbora (Microrasbora erythromicron) is a small, vibrant freshwater fish native to the peat swamps and rivers of Southeast Asia, particularly in Myanmar and Thailand. This species is known for its striking emerald-green coloration, which shimmers under aquarium lighting, making it a popular choice among aquarists. The fish typically measures about 3-4 cm in length, making it ideal for small community tanks where it can showcase its beauty without overwhelming the space.

In nature, Emerald Dwarf Rasboras inhabit densely vegetated areas where they seek cover among the plants. Their natural habitat is characterized by slow-moving waters and ample leaf litter, which provides both food and shelter. This species is peaceful and social, often seen in small schools in the wild. They exhibit intriguing behaviors, such as darting in and out of vegetation, which adds liveliness to any aquarium setup.

Emerald Dwarf Rasboras thrive best in well-planted aquariums with subdued lighting that mimics their natural environment. They prefer a soft, slightly acidic to neutral pH and require stable water conditions to maintain their health and vibrancy. These fish are relatively hardy but benefit from a well-maintained tank with regular water changes, which helps to replicate their natural habitat conditions.

Due to their small size and gentle nature, they are ideal for community tanks with other small, non-aggressive species. Their shimmering appearance and dynamic schooling behavior make them a captivating addition to any aquatic display, appealing to both novice and experienced aquarists alike.

To keep Emerald Dwarf Rasboras healthy, maintain water temperatures between 24°C to 28°C, with a preferred pH range of 6.0 to 7.5. They thrive in soft to moderately hard water, ideally with a hardness of 5-15 dGH. A minimum tank size of 40 liters is recommended to provide ample swimming space and cover for these small fish.

Feeding is straightforward, as they are omnivorous and will accept a variety of foods. High-quality flake food, micro-pellets, and live or frozen foods like daphnia and brine shrimp are excellent options for providing a balanced diet. Regular feeding, 2-3 times a day, ensures they receive adequate nutrition and helps maintain their vibrant color.

When introducing new fish to the aquarium, a proper acclimation process is essential to reduce stress. Gradually introduce the fish to the tank water over several hours. Quarantine new arrivals for at least two weeks before adding them to the main tank to prevent the spread of diseases. Emerald Dwarf Rasboras are peaceful and should be housed with other small, non-aggressive species to avoid aggression and ensure a harmonious community tank environment.

Emerald Dwarf Rasboras are sensitive to temperature fluctuations; thus, it is vital to maintain a stable shipping temperature between 24°C and 28°C. They should be packed in breathable bags with sufficient oxygen and minimal water volume to reduce stress during transit. It is recommended to ship no more than 10 fish per liter of water to ensure comfort. This species is not listed under CITES, making it easier to export.
