Cardinal Tetra 红莲灯鱼 (Buy 10 free 1)
Cardinal Tetras and Neon Tetras are similar in appearance and are often confused with each other. However, there is one very easily identifiable difference. In the Cardinal Tetra, the red stripe on the lower half of the body extends the full length of the fish from the eye area to the tail. In the Neon Tetra, the red stripe starts at mid-body, roughly below the dorsal fin, and extends to the tail.
Cardinal Tetras have surpassed Neons in popularity and are in high demand in the aquarium trade. As a result, they are often priced a little more highly than their smaller and less brilliant cousins. Although they prefer soft acidic water, as the Neons do, Cardinals are more demanding, preferring a pH below 6 and a hardness level below 5 dGH. Adult Cardinals will reach a length of nearly 2 inches. Like Neons, they are best kept in schools of five or more.
