Distribution and habitat
The range of the Orangefin Zebrafish is Kachin in northern Myanmar, where they occur in tributaries of the Ayeyarwaddy River. They live in small, fast-flowing streams with clear, often brownish water and shady bamboo growth on the banks.
Maintenance
The aquarium should have a dense border planting, with hiding and retreat possibilities (roots, stones) and offer a lot of swimming space. A coarse, round gravel as substrate with some foliage covered (e.g. sea almond leaves), slightly shaded light (floating plants) and a moderate current is ideal.
No ammonia, ammonium and nitrite should be detectable, the nitrate value should not exceed 100 mg/l. To ensure the water quality and oxygen content, a filter and heater adapted to the aquarium size is required, as well as lighting for the species-appropriate day-night rhythm of the animals.
Diet
In nature they feed mainly on insects and insect larvae. The food supply consists of live, frozen and dry food. For a balanced diet, feed once a day with a high-quality, protein-rich dry food (flakes, granules, pellets) as well as cyclops, daphnia, mosquito larvae or artemia (live or frozen).
It is recommended to feed small portions several times a day, which are eaten within a few minutes. A regular and varied diet promotes health and increases resistance.
Behaviour and compatibility
They are swimming and lively fish, which are well suited for a community tank with other peaceful fish. At least 5, but preferably much more Orangefin Zebrafish should be kept together
Basically, only mutually compatible fish species with similar demands on water conditions and water temperature should be socialized.
Sex dimorphism
The males are more slender and somewhat more colorful than the more plump females.
Reproduction and breeding
They are free spawners that do not engage in brood care. The male usually swims around (drifts) the female in the early morning, which spawns among fine-feathered plants. The larvae hatch after 24-36 hours and swim freely after a few days.
Fry must be fed several times a day with special rearing food (Artemia nauplii). In community tanks breeding is hardly possible, because the spawn is easy prey.
Important
Kyathit is the Burmese name for leopard. Populations from different locations often differ significantly in pattern and coloration.
The tank should be well covered, because they like to jump.
The well-being of the fish should be checked regularly. Temperature should be checked daily, pH, hardness and nitrate levels should be checked at least every 14 days. Regular partial water changes are recommended, even if the contaminant level has not yet reached the upper limit. Sudden changes in water quality should be avoided. Newly introduced fish must be accustomed slowly to the water in the aquarium.
