Etymology

Devario: appears to be derived from a local vernacular name for the type species of the genus Cyprinus (now Devario) devario Hamilton, 1822. neilgherriensis: n…

Distribution

Appears endemic to tributaries of the Bhavani river system in the Nilgiri Hills of Tamil Nadu state, southern India including the Pykara, Avalanche and Kaity s…

Habitat

Inhabits hill streams and upper parts of small rivers containing clear, well-oxygenated water with substrates of gravel and variably-sized rocks and some margi…

Aquarium size

An aquarium with surface dimensions of 120 ∗ 45 cm or similar should be the smallest considered.

Maintenance

Likely to fare best in an aquarium set up to resemble a flowing stream or river with a substrate of variably-sized, water-worn rocks, sand, fine gravel and per…

Probably not an aggressive fish but may intimidate slow-moving or timid tankmates with its constant activity and vigorous feeding behaviour, meaning it's most appropriate for aquaria containing robust, similarly-sized fishes.

There are plenty of suitable choices including many cyprinids, loaches, cichlids, catfish and characins, although as always when selecting a compatible community of fish proper research is essential.

It's a schooling species by nature and ideally should be kept in a group of at least 8-10 specimens which will not only make the fish less nervous but result in a more effective, natural looking display.

Based on experience with congeners any aggression will also be contained as the fish concentrate on maintaining their hierarchical position within the group, and males tend to display better colours in the presence of rivals.

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.
