Distribution and habitat

White fringed dwarf bluefish are native to the small tributaries to the Daying River (Yunnan, China), a tributary of the Irrawaddy River system in Myanmar. There they live in small, clear streams with a leafy substrate of stones and sand and dense riparian vegetation.

Maintenance

The aquarium should have a dense border planting, with many hiding places, such as roots, stone caves or bamboo tubes and offer free swimming space. A dark substrate of sand and fine gravel covered with some foliage (e.g. sea almond tree, oak), subdued light (floating plants) and soft, slightly acidic, oxygen-rich water is ideal.

No ammonia, ammonium and nitrite should be detectable, and 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

The food supply consists of live, frozen and dry food. For a balanced diet, feed once daily with plankton, cyclops, daphnia, moina and artemia (live or frozen). After habituation, dry food is also accepted, but should not be the main component of the diet. It is recommended to feed small portions several times a day. Only feed as much as will be eaten within a few minutes. A regular and varied diet promotes health and increases resistance.

Behaviour and compatibility

They should be kept in pairs or in a harem, one male with several females. The males of these shy and quite peaceful fish form small territories, which are consistently defended within the species. Keeping several pairs or harems is only recommended in a larger and richly structured tank. They should only be socialized with other small and not too lively fish, but it is better to keep them in a species tank.

Basically, only compatible fish species with similar demands on water quality and water temperature may be socialized.

Sex dimorphism

The males are more colorful and can be recognized by their straight or inwardly curved (concave) ventral line. The females are smaller and not so intensely colored.

Reproduction and breeding

They are substrate spawners and prefer to attach the spawn to the underside of fine-feathered plants. The larvae hatch after 2-3 days and swim freely after about 5 days. No brood care is practiced.

Fry must be fed several times a day with special rearing food (infusoria, Artemia nauplii). In a community tank breeding is hardly possible, because the young fish are easy prey.

Important

Dario dayingensis are very similar to Dario hysginon.

The foliage (sea almond tree, oak, etc.) enriches the water with humic substances, naturally lowers the pH and is a valuable secondary food source.

The well-being of the fish should be monitored regularly. Temperature should be checked daily, pH, hardness and nitrate levels 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
