[River Baby (Asian market); Cá Lòng Tong (Viet);
Rasbora argyrotaenia]
Found in the rivers of Southeast Asia, including Borneo and Indonesia, these are very tiny carp, growing to 4.7 inches long, but are commonly shorter. While primarily river fish, they will invade flooded rice fields. They are most known as an aquarium fish, but are also eaten, especially in Vietnam, where the fish is highly regarded.
