Description de l'espèce
Geographical Origin and Habitat: Irrawaddy River basin in northern Myanmar. Populates pristine mountain and hill streams, thick with bamboo and rocky pebbles, characterized by cool and rough waters.
Taxonomy and Morphology: Orange Finned Danio / Kyathit Danio (Danio kyathit). "Kyathit" in Burmese means "Leopard", referring to its spotted pattern, although there is a variant with continuous lines. Similar to Danio rerio, but more massive.
Social Behavior: Frantic, joyful, absolutely tireless. 100% gregarious: in schools of at least 8-10 units it best expresses the inter-male chases, which remain completely harmless.
Coloration and Sexual Dimorphism: Golden-bronze flanks furrowed by longitudinal series of sculpted black spots (or 3 or 4 solid horizontal stripes). Males are instantly recognized by the bright red-orange shades on the edge of all fins.
Soins, reproduction et cohabitation
Aquarium Setup: The water current must be sustained to simulate the stream. Tank of at least 80 cm (32 inches) in length. Fine sand or smooth gravel substrate covered with polished river stones. Strictly closed tank!
Diet and Feeding: Essentially insectivorous diet. Flake food is tolerated very well, but mosquito larvae, bloodworms, daphnia and live Drosophila will dramatically emphasize the orange fins.
Water Quality: Tolerates winters at 18°C (64°F) and domestic temperatures up to 25°C (77°F) well. If it exceeds 26°C (79°F) for a long time, the fish will suffer respiratory distress and lose part of its visual intensity.
Compatibility and Cohabitation: Perfect for hill stream tanks together with Balitorids (Sewellia), Garra, Botias and other Cyprinids tolerant of cool water (Pethia). A nightmare for shy or slow fish (like Discus or Gouramis).
Aquarium Breeding: Drops hundreds of non-adhesive eggs into the pebbly substrate. To save the eggs, a grid is needed or spawning on a thick carpet of Java Moss, then removing the parents (chronic egg cannibals).
Risks and Diseases: Primary risk of dying asphyxiated on the floor if the tank has open cracks. Fungal infections (Costia, Saprolegnia) are frequent in case of poor bottom hygiene.

Profil de poisson
- Tempérament
- Semi-aggressive
- The Orange Finned Danio is a peaceful, highly gregarious schooling fish. They are never aggressive toward other species, though their boisterous activity can be annoying to quieter fish. Intraspecific interactions consist of constant, harmless chasing and sparring among males establishing a loose hierarchy.
- Régime alimentaire
- Omnivore
- They are unfussy omnivores that naturally feed on insects, small crustaceans, and plant matter. In the home aquarium, they will readily accept high-quality flakes, micro-pellets, and freeze-dried foods. Supplementing with live or frozen foods like bloodworms and daphnia will bring out the intense orange coloration in their fins.
- Espérance de vie
- 3-5 years
- Taille adulte
- 4.5 cm
- Ratio des sexes
- Group
- Females are slightly larger, significantly plumper, and have less intense orange coloration on their fins. Males are slender and display bold, bright orange fins, especially when displaying to rivals or females. They must be kept in a group of at least 8-10 individuals with a roughly equal mix of males and females.
- Fréquence d'alimentation
- Twice daily
- Being highly active, they benefit from being fed small amounts two to three times a day. They are enthusiastic surface and mid-water feeders that will rapidly consume anything offered. Care should be taken to ensure slower tank mates get their share before the danios eat everything.
- Charge biologique
- Low
- The Orange Finned Danio produces a relatively low bioload individually, but typical schools will generate a moderate amount of waste. They are highly active fish that require regular feeding, which contributes to their bioload. Standard biological filtration and routine weekly water changes will easily maintain the necessary water parameters.
- Courant
- Stagnant
- Originating from small, fast-flowing streams in Myanmar, they thrive in aquariums with moderate to strong water flow. A powerhead or a strong filter return will encourage them to swim actively against the current, which they enjoy. Strong flow also ensures high oxygenation, which is crucial for these energetic fish.
- Risque de saut
- Yes
- Like all danios, they are excellent and frequent jumpers, presenting a very high jump risk. They will often leap out of the water when chasing each other, during feeding, or if startled. A completely sealed, tight-fitting lid is absolutely required to keep them safely in the aquarium.
- Reproduction
- Oviparous
- They are prolific egg scatterers that will easily breed in a well-conditioned tank. A separate breeding setup with a mesh bottom or dense marbles is required, as the adults will ravenously consume their own eggs. Once spawning is complete, usually in the early morning, the adults must be promptly removed.
- Compatibilité et compagnons
- Peaceful
- They are an excellent community fish, known for being peaceful and active. They mix well with other similarly sized, robust community fish like tetras, corydoras, and other danio species. However, their constant, high-speed darting may stress out slow-moving or highly timid species like certain gouramis.
- Niveau dans le bac
- Top/Middle
- They are predominantly top and mid-level swimmers, constantly patrolling the upper reaches of the tank. They are almost always in motion, requiring a long aquarium to provide adequate swimming space. While they don't hide much, they appreciate floating plants to break the water surface.
