Dadiburjor's Danio

Adults of this fish typically reach a length of 2 to 3 cm. Their body is adorned with a dark blue dotted line that runs horizontally from head to tail against a background varying from golden to orange. The belly has a silvery hue. The fins are colorless and translucent. Sexual dimorphism in Dadiburjor's Danio is weakly expressed, and males are practically indistinguishable from females based on external characteristics.

This species inhabits waters of South Asia, particularly in western India — in the states of Goa, Karnataka, Kerala, and Tamil Nadu. Preferred habitats are numerous river systems that originate in the Western Ghats mountains and flow into the Arabian Sea. They are characterized by shallow streams with abundant riparian and submerged aquatic vegetation.

These are peaceful and active fish. It is advisable to keep them in a school (at least 8–10 individuals) with similarly sized miniature cyprinid species, such as other danios or rasboras.

For a group of 8–10 individuals, an aquarium of at least 40 liters is recommended. The setup should ideally recreate a dimly lit space, abundant with aquatic vegetation and driftwood that can serve as shelters. The use of floating plants will help create additional shade. It is important to provide gentle filtration, avoiding strong water movement, as these small fish do not tolerate powerful currents well. A simple air-driven sponge filter can be an excellent solution. Keeping Dadiburjor's Danio is not particularly difficult; key aspects include quality feeding, maintaining stable water parameters (temperature, pH, and dGH), and regular aquarium maintenance procedures, including waste removal and partial water changes.

These fish do not have specific dietary requirements. A typical daily diet can consist of various dry foods, such as flakes, granules, or tablets. To enrich their diet, it is very beneficial to add live or frozen foods, for example, Artemia, small bloodworms, or Daphnia.

Under favorable conditions and a protein-enriched diet, spawning occurs regularly in these fish. The entire group spawns simultaneously, attaching eggs to leaves closer to the water surface. Since they lack parental instincts, the eggs can be quickly eaten by adult fish. To increase the chances of offspring survival, it is important to timely transfer the leaf with eggs to a separate tank. The incubation period lasts 2–3 days. After hatching, the fry remain attached for 4–5 days, feeding on the yolk sac reserves, and only then begin to swim freely. From this point, they should be fed microscopic foods, such as infusoria, and as they grow, Artemia nauplii and similar products can be included in their diet.

Most health problems in fish arise from unsuitable keeping conditions. If the fish has not been subjected to aggression from conspecifics and has not sustained physical injuries, then the cause is most likely poor water quality or food. Often, after eliminating these factors, the fish's body can cope with the ailment on its own. However, in the case of prolonged negative exposure, medication may be required. More detailed information on symptoms and treatment methods can be found in the "Aquarium Fish Diseases" section.

When selecting individuals, attention should be paid to their activity and the integrity of their skin. Healthy fish should be active, without visible damage, spots, or signs of emaciation. Avoid purchasing fish that isolate themselves, appear sluggish, or have clamped fins. Since the species is sensitive to water quality, it is recommended to assess the condition of the aquarium in the store: there should be no dead individuals, and the water should be clear and without a strong odor. It is best to purchase a group of 8–10 individuals at once, as fish experience severe stress when kept alone.
