Etymology

Danio: from Dhani, a Bengalese vernacular term for small, minnow-like cyprinids. albolineatus: from the Latin albus, meaning 'white', and lineatus, meaning 'li…

Distribution

Currently understood to be widely-distributed with records existing from parts of Myanmar, Thailand, Laos, Cambodia, Vietnam, Peninsular Malaysia and the Indon…

Habitat

Inhabits various habitat-types from well-oxygenated, clear streams with rocky substrates running through forested areas, to still bodies of water such as ponds…

Aquarium size

Minimum base dimensions of 90 ∗ 30 cm are recommended for this active species.

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…

Stomach analyses of wild specimens have revealed this species to be chiefly insectivorous, feeding on a variety of aquatic/terrestrial insects and their larvae.

Small amounts of algae, other plant material and organic detritus were also recorded but may have derived from the gut contents of prey items.

In the aquarium it's a largely unfussy feeder and will accept most foods.

A good quality dried product can be used as the staple diet but this should be supplemented with regular meals of small live and frozen fare such as bloodworm, Daphnia, Artemia, etc.

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.

Anything worth adding

Behaviour and compatibility

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 che…

Sexual dimorphism

Sexually mature females are usually rounder-bellied, slightly less colourful and a little larger than males. The differences are especially clear when the fish…

Reproduction

Like many small 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 wil…

Notes

Doubts remain whether D. albolineatus is representative of a single species or a group of similarly-patterned, closely-related fish, and the form from Chantabu…
