The glowlight danio (Danio choprae) is a fish species that comes from the northern Myanmar region. It is found naturally in the Irrawaddy River and, since the 2000s, these fish have become common aquarium fish. They belong to the Cyprinidae and Danio families and they closely resemble glowlight tetra fish in appearance. Despite this, they are more closely related to zebra danio fish. They can be found with a variety of saturated colors on their bodies and are more colorful than most fish in the Danio family. Their colors include green, red, orange, gold, blue, silver, yellow, white, and black.
Glowlight danios feed on insects, insect larvae, flake foods, dwarf shrimp fry, and other small animals. In aquariums or tanks, they should not be kept with larger fish that might hurt them. Males have more colorful bodies than females and fertilize eggs on the go while swimming. Glowlight danios do not care for their eggs after laying them, in fact, the eggs hatch into small fry in just 72 hours. The species is classified as Least Concern by the IUCN.

Glowlight danios (Danio choprae) live in the shallow waters of hill streams and are endemic to the Irrawaddy River in Myanmar. They exist at depths of 11.8-19.7 in (30-50 cm) in their freshwater habitat. They are able able to coexist with the golden zebra loach and other peaceful fish in an aquarium tank.

Did you know...
The name that is widely used for the glowlight danio is a bit of a misnomer. The fish was named Danio choprae in the year 1928 by scientist Dr. S. L. Hora for Dr. B. N. Chopra, who initially gathered the first specimen of the fish. However, since the suffix 'ae' relates to female names in Latin, the scientific name was later changed to Danio choprai.
Glowlight danios, surprisingly, do not get their names from glowfish, which are a variety of zebra danio rerio fish. The zebra danio rerio fish happens to be a close cousin of glowlight danios, with both of them belonging to the family Cyprinidae. Glowlight danios get their names from glowlight tetra fish, to which they bear a resemblance in appearance.
Glowlight danios are one of the most vivid and brightly colored species of the Danio family, with every color on their bodies being saturated to the maximum.
Glowlight danios also often go by the scientific name Celestichthys choprae.
Only between six and 10 glowlight danio fish should be kept together in a single school. And at least five zebra danios should be kept together in a school. This practice needs to be observed since they are schooling fish.
The minimum tank size that is required for glowlight danios is over 20 gallons. Proper glowlight danio care also includes maintaining a temperature of 61-79 F (16-26 C). Also, the tank should have a pH of 6-8, and the carbonate hardness should be between 1-12. The tank size plays an important role since glowlight danios are great jumpers. A tank size of more than 20 gallons prevents glowlight danios from jumping out of their tank.
Glowlight danios belong to the order Cypriniformes and the genus Danio. The male of the species is more colorful than the female. The body of a male is brighter, slender, and more colorful and the caudal fin, the dorsal fin, and the anal fin of the danio are all in different shades of color. Their caudal fins tend to have a black and gold color, theor dorsal fin has a yellow line, and their anal fin has a white line on it.
The breeding of danios has taken place for more than 72 years after they were first observed and classified. Now, the breeding of these aquatic animals is a business in its own right.
In their natural surroundings with plants, rocks, and substrate, danios have to be more active than in artificial aquarium surroundings. In the river, they must stay active to avoid being eaten by larger predators that habitually feed on them. It does this by swimming through marine plants and finding holes in rocks or spaces between them. In an aquarium, these danios do not disturb the plants that are simply there for show.
The glowlight danio has many great qualities which make it a great fish to have in an aquarium. It is endlessly adaptable and tough, it is largely peaceful and is extremely beautiful to look at. It can be kept in a school with different species of fish and it leaves your aquarium plants undisturbed. Their aquariums or tanks also do not need to be heated, since the glowlight danio thrives at room temperature water and is extremely adaptive and tolerant to any changes in temperature.
What to keep with a glowlight danio?
At a given time only a school of about 6 danios should be kept in a tank together. When designing an aquarium habitat or tank for glowlight danios, their compatibility with other fish should be accounted for. For example, its compatibility with other danio fishes is excellent which makes them excellent tankmates with each other, but not so much with larger size fishes like guppies. Other fish of smaller sizes can also make compatible tank mates with a glowlight danio.
The glowlight danio fish, being peaceful and shy, does well with other calm fish. They should not be kept with larger fish such as guppies, because they might end up harassing them. They get along great with all other danios, apart from the giant danio, since it is a much bigger fish. Other suitable tank-mates include anabantoids, tetras, loaches, livebearers, catfish, and rainbowfish.
An important step in glowlight danio breeding is taking the danios out of the tank after spawning to allow their eggs to hatch and become fry, otherwise, they might get eaten by the danio adults. The nature around a glowlight danio also is important, since a well-planted tank or aquarium keeps them happy. A well-planted tank or aquarium should include plenty of rocks.
The feeding of glowlight danios is easier than most fish since they eat basically any dry food that is given to them, including flake food. Feeding danios vegetable matter is also important. In their natural habitat, these danios eat insects and other larvae as food.
Does a glowlight danio have teeth?
These fishes have between one and three sets of pharyngeal teeth located in their throat, and they have a bony plate near the pharyngeal bone's end to grind their food as well.
