Descrição da espécie
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 Devario aequipinnatus; the verified classification records genus Devario, family Danionidae, subfamily Danioninae, order Cypriniformes. Historical names remain searchable as synonyms rather than separate species.
Social Behavior: Giant Danio is gregarious and should be kept in a school. The minimum reference is 6 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.
Cuidado, criação e companheiros de tanque
Aquarium Setup: Giant Danio needs an aquarium of at least 300 litres, sized for adult body size and a minimum group of 6 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 22–26 °C, pH 6.5–7.5. 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 a species to combine with caution, with a generally active temperament. Keep at least 6 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 “egg scattering”. 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.

Perfil de peixe
- Temperamento
- Active
- Giant Danio has a generally active temperament. Insufficient space, an unsuitable social ratio or incompatible tankmates can substantially change observed behaviour.
- Dieta
- Omnivore
- Giant Danios are omnivorous and not particularly fussy when it comes to their diet, accepting a wide variety of foods. Their staple diet should consist of high-quality flakes or granules designed for active community fish. To ensure optimal health and vibrant coloration, their diet should be supplemented with live or frozen foods such as bloodworms, Daphnia, and brine shrimp. They will enthusiastically feed at the surface and in the middle water column, often creating a frenzy during feeding time.

- 5-7 years

- Proporção sexual
- School
- Giant Danio is gregarious and should be kept in a school. The reference minimum is 6 individuals and must not be read as permission to overcrowd the aquarium.
- Frequência de alimentação
- Twice daily
- Due to their high energy expenditure, they benefit from being fed two to three times a day in small portions. Each feeding should only consist of what the entire school can consume within two to three minutes to prevent water fouling. Overfeeding should be avoided despite their voracious appetite, as it can quickly deteriorate water conditions. A consistent feeding schedule helps maintain their energy levels and overall health.
- Carga biológica
- Medium to High
- The Giant Danio is an active, fast-swimming species with a moderately high metabolism that contributes to a significant bioload. Because they are best kept in large schools of at least six to eight individuals, the collective waste produced by the group can quickly accumulate. A robust filtration system and regular water changes are strongly recommended to maintain optimal water quality. Adequate biological filtration is particularly important to process the ammonia generated by their active lifestyle.
- Fluxo
- Strong
- Native to fast-flowing streams and rivers in the Indian subcontinent, Giant Danios thrive in environments with significant water movement. They actively seek out areas of high flow in the aquarium, using it to exercise and mimic their natural habitat. Providing strong filtration or adding powerheads to create a linear current will greatly benefit their physical well-being. A tank that simulates a river-like environment with smooth rocks and driftwood is highly recommended.
- Risco de salto
- Yes
- These fish are notorious and powerful jumpers, capable of easily launching themselves out of an uncovered aquarium. Their streamlined bodies and strong muscles are adapted for jumping, a behavior often triggered by sudden changes in lighting, water parameters, or startling movements. A tight-fitting lid with no gaps around filters or heaters is absolutely mandatory. Floating plants can also help make them feel more secure and deter them from jumping.
- Reprodução
- Egg scatterer
- Giant Danios are egg-scatterers that provide no parental care to their offspring and will eagerly consume their own eggs if given the chance. Breeding typically occurs in the early morning, usually triggered by a significant water change with slightly cooler water. The female scatters non-adhesive eggs over fine-leaved plants or a spawning mop while the male simultaneously fertilizes them. To ensure a successful spawn and fry survival, a separate breeding tank with a mesh floor or marbles is recommended to protect the eggs.
- Compatibilidade e companheiros de tanque
- With caution
- The cohabitation profile is a species to combine with caution, with a generally active temperament. Keep at least 6 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.
- Nível do tanque
- Top/Middle
- Giant Danios are primarily surface and mid-water dwellers, constantly patrolling the upper half of the aquarium. They are rarely seen resting on the bottom unless they are sick or severely stressed. Providing ample open swimming space in the upper areas is crucial for their well-being. Tall background plants can offer them a sense of security while leaving the central mid-to-top areas open for their active swimming.
