Distribution and habitat
The red-striped danios are common in Peninsular Malaysia and West Kalimantan, Borneo. They live in the brown, humic water of shady, slow-flowing forest streams and weedy pools.
Maintenance
The aquarium should have a varied planting, which offers both shelters, as well as swimming space and roots that serve as a retreat. In soft, slightly acidic water, subdued light (floating plants) and a dark substrate covered with some foliage (e.g. sea almond leaves) they show the most beautiful coloration.
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 on insect larvae, small crustaceans, worms and other zooplankton. The food supply consists of live food, such as daphnia, cyclops, artemia, mysis and mosquito larvae, which are also well accepted frozen, plus commercially available frozen special food mixtures, supplemented with a high-quality, protein-rich dry food (granules, flakes, micropellets).
Only feed as much as is eaten immediately (in a maximum of 10 minutes). A regular and varied diet promotes health and increases resistance.
Behaviour and compatibility
They are lively and very peaceful schooling fish that can be socialized well with other small, peaceful fish. At least 5, but preferably much more red stripe danios should be kept together.
Basically, only compatible fish species with similar requirements for water conditions and water temperature should be socialized.
Sex dimorphism
The slimmer male has an almost straight abdominal line, which is rounded in the female.
Reproduction and breeding
They are frail spawners and spawn predators. The female spawns among fine-feathered plants (java moss) near the bottom. The larvae hatch after 18-48 hours and swim freely after 3-4 days.
Fry must be fed several times a day with special rearing food (Artemia nauplii, dust food). In a community tank breeding is hardly possible, because the spawn is easy prey.
Important
The aquarium should be well covered, because they like to jump.
The well-being of the fish should be checked regularly. The temperature should be checked daily, the pH, hardness and nitrate value 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.
