The Dwarf Rasbora, encompassing species like Boraras maculatus and Boraras brigittae (Chili Rasbora), is a truly enchanting and miniature freshwater fish highly prized in the aquarium hobby, especially for nano and planted tanks. Reaching an adult size of typically less than an inch (2.5 cm), these tiny jewels are known for their vibrant and often iridescent colors, ranging from reddish-orange to a subtle silver, frequently adorned with distinctive dark spots or stripes that intensify under optimal conditions and good lighting. They are exceptionally peaceful and display a shy, schooling nature, making them ideal inhabitants for community tanks with other small, gentle species, including various dwarf shrimp. Dwarf Rasboras thrive in well-planted aquariums with plenty of hiding spots, a dark substrate, and soft, slightly acidic water conditions that mimic their native blackwater habitats in Southeast Asia. Keeping them in groups of 8-10 or more is crucial for their well-being, as it encourages natural schooling behavior, reduces stress, and enhances their brilliant coloration. Their diet should consist of high-quality micro-pellets, crushed flakes, and small live or frozen foods like cyclops, daphnia, or newly hatched brine shrimp to ensure optimal health and vibrancy.
