a trademarked brand of fluorescent zebrafish that appear to glow in the dark under ultraviolet light. ''Danio choprae'' is an active danionin species that spends most of its time on mid-water levels. This species feeds on insects that have fallen into the water, aquatic insect larvae, and other small animals. In the aquarium, it accepts most foods offered, including most dry foods. It has a streamlined body marked with a brilliant orange longitudinal band and a series of vertical blue-black bars on the flanks. The fins are edged with yellow.

S. L. Hora originally named this fish ''Danio choprae'' after Dr. B. N. Chopra. However, names ending in '-ae' are feminine and reserved for Latin names honouring women. Latin names honouring men usually end with '-i', and consequently the fish name sometimes is reported as ''Danio choprai''
