Danio choprae

Despite the peaceful nature of Danio choprae towards other species, some aggressive behaviour can be observed among fishes of their own species.

Danio choprae

Danio choprae was first described by Hora in 1928. The name that was given to this species in its first description, is still valid. In the course of time, however, several synonyms have emerged. Therefore, these fish can also be found as Celestichthys choprae, Brachydanio choprai and Danio choprai. Especially the last synonym, D.choprai, is similar to the official valid name. This similarity often leads to confusion on the official name of this species.
The name choprae is named after Dr. B.N. Chopra by Hora in his initial study of these fish.


Similar to other Danio species is the body of Danio choprae elongated. Dark Blue vertical bars can be found on its green body. In addition, a blue horizontal bar, located dorsally, runs across the entire body. The fins are translucent with the exception of a yellow tips at the ends of the caudal fin. In addition, a yellow line can be seen running horizontally on the dorsal fin. The anal fin, also displays a line across it. However, the line is white instead of yellow on the anal fin.

There are barely any differences between males and females. Males are more colorful whereas females are a bit larger and rounder bellied.

Distribution and Habitat

Danio Choprae is only found near Kamaing and Mogaung. These are found near the city Myitkyina. The fish are caught in the river Mogaung Chaung and the surrounding streams. This river is a tributary of the Irrawaddy (Also known as Ayeyarwaddy). This river flows in Kachin state which is located in Myanmar (Burma).

In the study of Kullander (2012) the fish were found in a pool of 30 m (32.8 yards) wide and 30 to 50 cm (11.8-19.7 inches) deep. Out of this pool, a small stream of 30 cm (11.8 inch) wide and 20 cm (7.8 Inch) deep emerged. The water here was very clear with a temperature of 24,8°C (76.6°F)and a pH of 7.6. The conductivity of the water was measured at 11 μS/cm. The substrate consisted out of mud. However, they are also collected on substrates of rocks and gravel. The waters do not contain any aquatic vegetation.


Danio choprae is not difficult to feed. It will accept almost every type of food. Fabricated foods are, therefore, easily accepted. However, do keep in mind that this is a carnivorous species. So its main diet should mainly consist of carnivorous foods.

The Aquarium

Since this species can be found in streams with a moderate current, some current needs to be present in the aquarium. In addition, a substrate of gravel and sand in combination with rocks and some driftwood will mimic the natural habitat. However, if one chooses for a black dark substrate over sand, the colours of the fish will become more pronounced. In addition, do plants enhance the colouration as well. Keep in mind that the aquarium should be closed off. Otherwise, the fish will jump out of the tank.

Despite their peaceful nature towards other species, some aggressive behaviour can be observed among fishes of their own species. Specimens ranked higher in the hierarchy will bully those that are ranked lower. Therefore, Danio choprae should always been kept with enough specimens. This will divide the aggressiveness over more individuals resulting to a lower chance of fishes being bullied to death. Torn fins are, however, hard to prevent and will be observed from time to time.

Breeding Danio choprae

Breeding Danio choprae is relatively easy. Spawning may even occur in a community aquarium. to increase the yield, however, a special breeding aquarium should be created.
This aquarium should be decorated in such a way that the parents cannot eat their own eggs. This can be done in various ways. For instance, a substrate of marbles or a grid above the substrate will prevent the fish from reaching their eggs. However, another option is to plant a lot of plants and create a dense vegetation. Mosses like Java Moss are especially suited for this. This will make it harder for the fish to find their eggs and eat them. Specially crafted breeding mops can be used for this purpose as well.

The pH of the water should be set at 7 with a relatively high temperature. The fish can be triggered by slowly filling the tank, which should be half full, over the course of several hours. This will mimic the monsoon and get the fish in the mood for mating. The next morning the fish will start to spawn.
Once the eggs are laid, the fish should be removed from the tank. To prevent eggs or fry to be sucked into the filter, the current should be decreased. 3 days after spawning, the eggs will hatch. A few days later the fry will start to swim freely. From now on they do need to be fed with small fabricated foods or infusoria.
