Moustached Danio (Danio dangila) Care Guide
Danio dangila is among the largest Danio species, with long barbels and a reticulated pattern, needing a roomy tank for its active shoals.
Compiled by Aquairi from published sources · Published · Updated
Overview
Danio dangila, the moustached danio, is one of the largest members of the genus Danio and is the type species of the revalidated genus. Its common name refers to its exceptionally long barbels. It is an active shoaling fish that requires plenty of swimming room.
Taxonomy
- Family: Cyprinidae
- Genus: Danio (type species)
- Scientific name: Danio dangila
Habitat
It occurs through the Ganges River basin, with most records from Nepal and from the Brahmaputra drainage in India and Bangladesh; it is also reported from Bhutan tributaries and Myanmar. Habitats range from mountain streams to sluggish, swampy waters with dense marginal vegetation, and the species is adaptable across different altitudes.
Tank requirements
- Minimum tank volume: 200 L
- Temperature: 18-26 °C (64-79 °F)
- pH: 6.5-7.8
- GH: 5-18 °dGH
- School size: at least 6 individuals (8-10 recommended)
- Lifespan: 5-8 years
A large aquarium with a long footprint and good swimming length suits this active fish; a filter providing several turnovers per hour helps replicate its flowing-water origins. The species reaches a substantial size for a danio.
Diet
In the wild it preys on insects and larvae. In the aquarium it is an unfussy feeder, accepting dried staples supplemented with bloodworm, Daphnia and Artemia.
Compatibility
It is not aggressive but is very active and may disturb slow-moving tankmates, so it suits communities of robust, similarly sized fish. Keep it in groups of at least 8-10; very small fish make poor companions and should be avoided.
Breeding
It is an egg-scatterer with no parental care. Breeding is considered trickier than in other danios, but has been achieved with groups conditioned on live foods.
Moustached Danio (Danio dangila) Breeding Guide
Overview
Danio dangila is the largest Danio species and spawns without parental care, per Seriously Fish. Documented aquarium spawning is limited; one recorded success involved a group of 8 adults of the Meghalaya population that spawned during a thunderstorm after a period of conditioning with live foods.
Sexing
Females develop a rounder belly and display a white stripe on the distal edge of the anal fin, whereas males show red colouring there instead; the difference is clearest in spawning condition as males intensify in colour and females fill with eggs (Seriously Fish).
Conditioning
Live foods are essential preparation. Seriously Fish notes a good quality dried product can form the staple, supplemented with regular meals of small live and frozen fare such as chironomid larvae (bloodworm), Daphnia and Artemia.
Breeding Setup
- Spawn a conditioned group rather than a single pair (the documented success used 8 adults).
- A coarse gravel substrate, into which the eggs fall, with the females leading and males following (Seriously Fish).
- Soft to moderately hard water; the species range is recorded at 16-24 C, pH 6.5-7.5 and 36-268 ppm hardness.
Spawning Behavior & Trigger
In the documented case the fish spawned within the coarse gravel substrate, females leading and males behind, during a thunderstorm following live-food conditioning (Seriously Fish).
Egg & Fry Care
Eggs hatch in about 48 hours and the fry become free-swimming roughly 48 hours later. They accept Artemia nauplii and fry foods and grow quickly, reaching 12-15 mm within 30 days (Seriously Fish).
Common Challenges
This species can be trickier than smaller danios, and documented aquarium spawning is scarce, so a conditioned group, coarse gravel and live-food preparation are the practical levers. The larger adult size also calls for a correspondingly large spawning space.
