The Vietnamese Cardinal Minnow, scientifically known as Tanichthys micagemmae and often referred to as the Vietnamese White Cloud, is a small, peaceful schooling fish prized for its shimmering colors, hardiness, and calm nature. Perfect for both tropical and cool-water setups, this Vietnamese minnow is ideal for planted and community aquariums. With their bright red fins and sparkling silver-blue bodies, Vietnamese Cardinal Minnows bring energy and color to nano tanks and larger displays alike. Discovered in the cool streams of Vietnam’s central highlands, the Vietnamese Cardinal Minnow is closely related to the well-known White Cloud Mountain Minnow. Unlike its Chinese cousin, this species displays deeper coloration, sleeker body lines, and more vivid red-orange hues in the fins. Adaptable to a wide range of water conditions, Tanichthys micagemmae thrives in aquariums with gentle flow and dense vegetation, making it a favorite among aquascaping enthusiasts. A full-grown Vietnamese Cardinal Minnow reaches about 1–1.2 inches (2.5–3 cm) in length, making it a perfect choice for nano aquariums. Males exhibit more intense red and gold tones, while females are slightly rounder and paler. Under good lighting, their silver bodies shimmer with blue-green reflections, a subtle yet captivating beauty that enhances any minnow fish aquarium. Vietnamese Cardinal Minnows are peaceful, social schooling fish that thrive in groups of six or more. Their gentle behavior makes them excellent tank mates for other small community species such as Rasboras, Danios, small Tetras, shrimp, and snails. They are active mid-level swimmers that enjoy cooler water temperatures and calm surroundings.
