Description: It has a elongated and laterally compressed, olive-green body marked with a brilliant orange or red longitudinal band and a series of vertical blue-black bars on the flanks. There is a red stripe on the back of the fish, which glows brightly under bright light. The fins are silvery-blue, the dorsal and anal fins have yellow longitudinal bands, while caudal fin has yellow edges. Their color only looking its best when they are properly kept in schools. The Glowlight Danio was described in honor of Dr. Chopra by Hora in 1928, but it did not become popular in the hobby until the last few years.

Mature females are a little larger and plumper, but not as colorful as males. During spawning it can be very conspicouos, when males intensify their color and females are full with eggs. Glowlight Danios are egg-scatteres. Well-fed fish will usually spawn every 10 days, and it is possible that a small numbers of fry survive in the community tank. They can be bred in pairs or in group in a small (10-15 litres) tank with a little water-current. Add some java moss or spawning mops to the breeding tank. Spawning can be initiated by adding small amounts of cool water every few hours. The fish should spawn in the following morning. A female will produce about 50 relatively large eggs, which are sink to the bottom. After spawning the parents should be removed. The fry hatch after 72 hours and become free-swimming after 2 days. Feed them with infusoria or liquid foods. After 3 days they can usually eat newly hatched brine shrimp. At about three weeks of age the fry get a red stripe on their sides, and they will have the normal adult coloration when they become 2 months old. They become sexually mature at 6 months of age.
