Acrossocheilus paradoxus favors perching at the point where the river flows rapidly and contains a highly dissolved oxygen concentration. Acrossocheilus paradoxus is a special breed in Taiwan; its body presents the color of Yellow-Green while the abdomen region appears slightly white in color, and on the side of its body, it contains seven black belts. These features can be observed clearly during its infancy, but when it achieves adult status, the color of its body dims and the black belts become unclear.
Acrossocheilus paradoxus is omnivorous and primarily feeds on moss on rocks and water insects. The roe is inedible and its toxins can cause diarrhea, dizziness, and vomiting.
