These adorable, peaceful little cold-water fish are easy to care for and breed. Mature males have long fins, which they flare at each other to display dominance. These Vietnamese minnows (related to the Chinese White Cloud Mountain Minnow) are the smallest of the Tanichthys family and grow to a maximum length of only 1 to 1.25 inches. They’re great for nano tanks or small community aquariums!
