Least Rasbora (Boraras urophthalmoides)** – One of the smallest aquarium fish available, growing to just about 1 inch (2.5 cm). Native to Southeast Asia, this delicate species is p rized for its slender body, dark lateral stripe, and distinctive tail spot that resembles an exclamation mark. Least Rasboras thrive in planted aquariums with soft, slightly acidic water and do best in peaceful shoals of six or more. Hardy yet elegant, they add movement and charm to nano and community tanks. Perfect for aquarists seeking a tiny, colorful, and low-maintenance species, Least Rasboras are ideal companions for other small fish such as pygmy Corydoras, Sundadanio, and dwarf shrimp. With proper care, they can live 4–8 years, making them a long-lasting addition to your aquarium. Show more
