Etymology

Danio: from Dhani, a Bengalese vernacular term for small, minnow-like cyprinids.

Distribution

Collected from the Tanintharyi River drainage, a tributary of the Tenasserim River system in Tanintharyi (formerly Tenasserim) Division, southern Myanmar.

Habitat

No details are available but expect it to inhabit quieter, slower-moving sections of streams and minor rivers.

Aquarium size

An aquarium with base dimensions of 120 ∗ 30 cm48 ∗ 12 in or equivalent should be the smallest considered.

Maintenance

Looks particularly effective in a heavily-planted arrangement with a darker substrate, and may appear paler in sparsely-decorated set-ups. We suggest maintaini…

Diet

Probably preys on insects and their larvae in nature. In the aquarium it's largely an unfussy feeder and will accept most foods. A good quality dried product o…

This species is very peaceful indeed making it an ideal resident of the well-furnished community tank.

Since it places no special demands in terms of water chemistry it can be combined with many of the most popular fish in the hobby including other small cyprinids as well as tetras, livebearers, rainbowfishes, anabantoids, catfishes and loaches, though its adult size must be taken into consideration.

It's a schooling species by nature and really should be kept in a group of at least 8-10 specimens.

Maintaining it in decent numbers will not only make the fish less nervous but result in a more effective, natural-looking display while males will also exhibit their best colours as they compete with one other for female attention.

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 profileFor example, the Behaviour and compatibility section already says this.

Anything worth adding

Describe what you saw, or which part of the source says this.

Sexual dimorphism

Males have an overall yellowish-green body colour which extends into the fins whereas females are predominantly blue.

Reproduction

Like most cyprinids this species is an egg-scattering spawner that exhibits no parental care. That is to say when the fish are in good condition they will spaw…

Notes

This probable undescribed species first became available to aquarists in 2002, with males and females marketed as 'Danio sp. hikari yellow' and 'D. sp. hikari …
