White Cloud Mountain minnows (Tanichthys albonubes) are considered good fish for beginners, as they are extremely forgiving with regard to aquarium temperature and water quality. They are often sold as ideal "starter fish" for cycling a new aquarium, however it is kinder if they are introduced to an already cycled tank. They are schooling fish, and feel most comfortable in a group of at least five. An individual of these minnows kept alone may become timid and lose its bright color. White Clouds are generally peaceful and happy to coexist with other fish, as long as they are not put in a tank with larger fish that may eat them. The minnows are usually top or middle-level swimmers and rarely swim close to the bottom of a tank.
