Etymology

Dario: derived from the specific epithet of the type species, dario, which in turn is from its Bangla name, Darhi.

Distribution

Endemic to Kachin State in northern Myanmar. The type locality is a mountain stream south of Mogaung in the Ayeyarwaddy River basin. A pair of males from separ…

Habitat

No details are available although the possibly sympatric D. hysginon shows a marked preference for small, often turbid pools with dense growths of aquatic plan…

Aquarium size

A pair or small group with a male and several females can be housed in an aquarium with a base measuring 45 ∗ 30 cm or more.

Maintenance

Best-maintained in a well-structured arrangement with plenty of cover. A soft substrate is preferable although fine-grade gravel is acceptable, while ideal pla…

Water conditions

Temperature: It is subject to seasonal temperature fluctuations in nature and is comfortable within the range 59 - 77°F/15 - 25°C with even greater extremes be…

Diet

Dario species are micropredators feeding on small aquatic crustaceans, worms, insect larvae and other zooplankton. In captivity they should be offered small li…

Behaviour and compatibility

Given its rarity the emphasis should be on captive reproduction and we strongly recommend maintaining it alone. It's not a gregarious fish as such and rival ma…

Sexual dimorphism

Males are far more brightly-coloured and develop extended pelvic, dorsal and anal fins than females as they mature. In addition females are smaller and possess…

Reproduction

Substrate-spawner forming temporary pair bonds.

Other fishes are best omitted if you want to raise good numbers of fry, although in a mature, well-furnished community a few may survive to adulthood.

Either a single pair or a group of adults can be used but if using multiple males be sure to provide each with space to form a territory with around 30 cm² per individual adequate.

One male will usually become dominant meaning the others will not be involved in breeding.

Water parameters should be within the values suggested above and the fish conditioned with plenty of live and frozen foods.

As they come into breeding condition males will begin to form territories and display courtship behaviour alongside an intensified colour pattern.

This can be prolonged for several days with the female often being chased away then courted again minutes later.

The male will make a non-aggressive approach towards the female and appear to 'invite' her into the centre of his territory, and if ready to spawn she will follow.

The act itself is over in just a few seconds with eggs being scattered in a random fashion on the underside of a solid surface such as a plant leaf.

Post-spawning the female is ejected and the male takes sole responsibility for the territory.

If you want to maximise the numbers of fry raised now is the time to either remove the medium to a container containing water from the spawning tank or the adults as the fry will be preyed upon once hatched.

The incubation period should be 2-3 days after which the fry may need up to a week to fully absorb the yolk sac.

They are very small indeed and will require an infusoria-type diet until large enough to accept microworm, Artemia nauplii, and suchlike.

Where does this come from?

My own experienceFor example, I've kept twelve in a planted 60 cm tank since March 2024.A website I sawFor example, an IUCN Red List assessment, a museum catalogue or a FishBase page.A paperFor example, Marshall et al. (2011), Water temperature differences in interfluvial palm swamp habitats of Paracheirodon axelrodi and P. simulans.A book, or something not onlineFor example, Tappin (2010), Rainbowfishes: their care and keeping in captivity.Something already on the pageFor example, the Behaviour and compatibility section already says this.
