Malabar danio (Devario malabaricus ) – tropical aquarium fish of the carp family, one of the larger representatives of the Devario family.


Asia . Malabar danio lives in streams and rivers in western India and Sri Lanka. Found in clear, well-oxygenated waters with gravelly ground. The current, depth and clarity of the water in which they live vary greatly depending on the season.

Characteristics and disposition

In the wild, it can reach 15 cm in length. In aquarium conditions it rarely exceeds 10 cm. Body color varies from yellow to green, decorated with three or four blue stripes running along the trunk, from the gill covers to the base of the tail, interrupted in several places by colored spots and transverse stripes. The females during the spawning period have a more rounded belly and their central blue stripe at the rear bends a little upwards. A shoal species, it is recommended to keep at least 8-10 individuals in a group .

Most of them look prettier, are less skittish and show natural behavior. When kept individually they become aggressive. They are very mobile, therefore the most important factor when choosing an aquarium is its length. They spend most of their time in the upper and middle parts of the reservoir.

Nutrition and feeding

In nature, they mainly hunt insects and their larvae, in the aquarium they do not cause problems and eat most of the available food, but prefer those that remain afloat .

Malabar danio can be fed with good quality dry food, regularly giving live or frozen food, such as artemia, daphnia, bloodworm. Such a diet will provide them with the best color and condition.


They require an aquarium of at least 100 cm in length, planted only on the back and sides, with a large area left for swimming. They will do best in a river-like reservoir with sandy or gravel ground, smooth stones and a few boulders. You can also use dry roots and branches for decoration.

In such an environment, durable plant species attached to decoration, such as Mikrozorium, Bolbtis or Anubias, will be the best. Due to their ability to pop out, the aquarium should be equipped with a cover. Water should be clean, well-oxygenated with forced movement. Regular water changes in the amount of 30-50% are recommended. They are not aggressive fish, but their mobility can disturb more peaceful species.

They are best kept in an Asian biotope aquarium with gentle barbs, razors or labyrinth fish. In a social aquarium, good roommates will be other carp fish, tetras, cichlids, loaches, cuirass and catfish.


Like most small carp, they scatter eggs and do not care for their offspring. In a well-kept and overgrown tank, spawning often takes place without the intervention of an aquarist and individual fry may appear. However, a more controlled approach is required if we want to raise more fry.

Spawning tank 60 x 30 x 30 cm required, not too brightly lit. It is worth lining the bottom with something like a net, with meshes large enough for the roe to pass through them and at the same time for parents to have no access to it. You can also use artificial grass, glass balls, an aquarium mop and preferably a large number of small-leaved live plants, e.g. java moss. The water should be slightly acidic with a temperature of about 25-26 ° C, well oxygenated with forced light movement.

We stimulate adult fish by feeding them live food more often. Then we select one or two pairs and transfer them to the breeding aquarium. Spawning usually takes place within 24 hours. After spawning, the female is clearly more slender. After 48 hours, the parents should be caught.

Hatching time depends on the temperature and usually takes between 24 and 36 hours. The larvae begin to swim freely after the next few days. The first food should be plankton or other micro-sized artificial foods, then artemia larvae, micro nematodes and powdered dry foods may be fed.
