Description de l'espèce
Geographical Origin and Habitat: A freshwater species; the enclosure should provide stability, oxygenation, space and shelter consistent with its behaviour without turning one habitat description into a mandatory recipe.
Taxonomy and Morphology: The accepted scientific name is Danio albolineatus; the verified classification records genus Danio, family Danionidae, subfamily Danioninae, order Cypriniformes. Historical names remain searchable as synonyms rather than separate species.
Social Behavior: Pearl Danio is gregarious and should be kept in a school. The minimum reference is 8 individuals; sex, maturity and available space can require a more conservative composition. Observe access to food, resting behaviour, chasing and use of shelter. Isolation, persistent competition or aggression means the number, composition or environment needs to be corrected.
Coloration and Sexual Dimorphism: Colour and shape can vary with age, sex, physiological state and environmental conditions. Identification and sexing require recognized species-level characters; one appearance or photograph is not enough.
Soins, reproduction et cohabitation
Aquarium Setup: Pearl Danio needs an aquarium of at least 80 litres, sized for adult body size and a minimum group of 8 individuals. Filtration, shelter and swimming room must match the species and the actual number kept. Volume alone does not make an enclosure suitable: tank shape and length, usable area, oxygenation and the ability to separate territories must reflect adult behaviour.
Diet and Feeding: The recorded diet is omnivorous. Offer appropriately sized foods varied within that category, and adjust quantity and frequency from actual intake, body condition and leftovers. One food or a fixed schedule is not suitable for every age and situation.
Water Quality: Maintain stable, well-oxygenated water appropriate to a freshwater species; the card's reference values are 20–25 °C, pH 6–7.5. Verify conditions with reliable tests and size maintenance and filtration to the actual load. Ranges are not automatic thresholds for treatment or rapid chemical correction.
Compatibility and Cohabitation: The cohabitation profile is suitable for a compatible community, with a generally active temperament. Keep at least 8 individuals; tankmates, stocking density and decor must allow escape, rest and feeding without excessive competition. Watch interactions especially during feeding, maturity and breeding. Persistent chasing, injury or exclusion from food requires a change in stocking or layout, or separation of the animals.
Aquarium Breeding: The recorded reproductive profile is “oviparity”. Breeding should be attempted only with healthy adults, separation capacity and a plan for eggs or young. Do not treat unverified triggers, sex ratios or hatch times as universal for this species.
Risks and Diseases: Use a secure cover and close escape gaps. Prevent problems through quarantine of new arrivals, stable water, appropriate feeding and daily observation. Similar signs can have different causes, so check parameters, history and diagnosis before medication. Follow the product label and qualified aquatic-veterinary advice; there is no universal reduced dose for a species or family.

Profil de poisson
- Tempérament
- Active
- Pearl Danio has a generally active temperament. Insufficient space, an unsuitable social ratio or incompatible tankmates can substantially change observed behaviour.
- Régime alimentaire
- Omnivore
- In the wild, they are omnivorous micro-predators feeding on small insects, zooplankton, and algae. In the aquarium, they are unfussy eaters that will readily accept high-quality flakes, micro-pellets, and freeze-dried foods. Supplementing their diet with live or frozen bloodworms, daphnia, and brine shrimp will enhance their iridescent colors.
- Espérance de vie
- 3-5 years
- Taille adulte
- 6 cm
- Ratio des sexes
- School
- Pearl Danio is gregarious and should be kept in a school. The reference minimum is 8 individuals and must not be read as permission to overcrowd the aquarium.
- Fréquence d'alimentation
- Twice daily
- Due to their high activity levels and fast metabolism, they should be fed small amounts two to three times daily. They are surface and mid-water feeders that eagerly attack food as soon as it hits the water. Ensure they consume all offered food within a few minutes to prevent water pollution.
- Charge biologique
- Low to Medium
- The Pearl Danio produces a relatively low bioload individually, but they must be kept in schools, which collectively produce a moderate bioload. They are extremely active fish that consume a fair amount of food, contributing to waste production. Standard, efficient biological filtration and regular weekly water changes are sufficient to maintain good water quality.
- Courant
- Stagnant
- Originating from clear, flowing streams in Southeast Asia, they appreciate moderate to strong water flow. A powerhead or strong filter return provides the current they enjoy swimming against, keeping them active and healthy. Good surface agitation is also important to maintain high dissolved oxygen levels.
- Risque de saut
- Yes
- Danios are notorious jumpers, and the Pearl Danio is no exception. They will easily leap out of the water if startled by sudden movements, lights, or when playing near the surface. A tight-fitting lid with no large gaps around the filter output is absolutely mandatory.
- Reproduction
- Oviparous
- They are prolific egg scatterers that are very easy to breed in captivity. A conditioned pair or group placed in a separate breeding tank with marbles or a breeding mop will spawn at first light. The parents will eagerly eat their own eggs, so they must be removed immediately after spawning is complete.
- Compatibilité et compagnons
- Community
- The cohabitation profile is suitable for a compatible community, with a generally active temperament. Keep at least 8 individuals; tankmates, stocking density and decor must allow escape, rest and feeding without excessive competition. Watch interactions especially during feeding, maturity and breeding. Persistent chasing, injury or exclusion from food requires a change in stocking or layout, or separation of the animals.
- Niveau dans le bac
- Top/Middle
- They are highly active fish that predominantly occupy the upper and middle levels of the aquarium. They are constantly in motion, darting back and forth across the length of the tank. While they appreciate some floating plants for cover, they require plenty of open swimming space.
