Dwarf Rasbora (Boraras maculatus)
The Dwarf Rasbora (Boraras maculatus) is a tiny, peaceful freshwater fish known for its striking coloration and delicate spotted patterns. Native to Southeast Asia, including blackwater streams in Malaysia and Indonesia, this species is perfect for nano tanks and well-planted aquariums.
Boraras maculatus grows to only about 0.8 to 1 inch in length, making them one of the smallest rasboras available. Despite their size, they are active swimmers and display beautiful schooling behavior when kept in groups of at least 8 to 10 individuals. A larger school enhances their confidence and showcases their natural activity.
These fish thrive in heavily planted tanks with gentle water flow, soft substrates, and plenty of hiding spots. Floating plants can help diffuse light and provide cover, replicating their natural blackwater habitat.
Ideal water conditions include a temperature of 72°F to 79°F, a slightly acidic pH of 5.5 to 7.0, and soft water. Stable, clean water is critical, as Dwarf Rasboras are sensitive to poor water quality.
Boraras maculatus are omnivorous and will eat high-quality micro pellets, flakes, and tiny live or frozen foods such as daphnia, microworms, and baby brine shrimp. Feeding small amounts multiple times a day helps maintain their health and vibrant colors.
These peaceful fish are compatible with other small, non-aggressive species like other dwarf rasboras, small tetras, and pygmy corydoras. Avoid housing them with larger or aggressive fish that may stress or prey on them.
The Dwarf Rasbora is hardy, colorful, and full of life, making it an excellent choice for nano aquariums and planted community tanks. With proper care, they can live up to 3 to 4 years, adding energy and beauty to any aquarium setup.
