Distribution

Native to the Chao Phraya and lower Mekong river basins in Laos, Thailand and Cambodia and is widespread in Peninsular Malaysia with its distribution also exte…

Habitat

Clearly an adaptable fish as it has been collected various types of habitat including swiftly-flowing forest hill streams with substrates of boulders, smaller …

Aquarium size

Choice of decor is not as critical as water quality and the amount of open swimming-space provided. We suggest keeping it in a large, well-planted aquarium or alternatively it would look superb in a set-up designed to resemble a flowing river with a substrate of variably-sized rocks and gravel and some large water-worn boulders. A rivertank manifold could also be constructed to provide naturalistic unidirectional flow. The tank can be further furnished with driftwood branches and aquatic plants for aesthetic value. While the vast majority of plant species will fail to thrive in such conditions possibilities include hardy species such as Java fern, Bolbitis or Anubias species which can be grown attached to the decor.

It will also do well in a tank set up to recreate a peat swamp-type environment with dim lighting, roots and branches, leaf litter and real peat fibre added to the filter or mixed into the substrate. You could also add aquatic plant species that can survive under such conditions such as Microsorum pteropus (Java fern), Vesicularia dubyana (Java moss) and Cryptocorynes. In either situation the tank must have a very tightly-fitting cover as this species is a surface-dweller, an accomplished jumper and can escape through the tiniest of gaps. Like many other species that hail from such pristine natural environments it is intolerant to the accumulation of organic wastes and requires spotless water at all times in order to thrive.

It may be wise to ask about the origin of your fish before purchase as populations from flowing waters may require acclimatisation to more acidic, less-oxygenated conditions and vice versa. The widely-available captive-bred fish are likely to be adaptable to both sets of conditions but wild fish might be more delicate. This species also seems to react badly if introduced to the aquarium too quickly so try to acclimatise it over a couple of hours if possible.

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.

Water conditions

Temperature: 22 – 25 °C72 – 77 °F pH: 5.0 - 8.0 depending on the origin of the fish but somewhere between 6.5 - 7.5 usually proves ideal in the aquarium. Hardn…

Diet

According to stomach analyses of wild specimens this species feeds mainly on invertebrates both aquatic and terrestrial, particularly insects. In the aquarium …

Behaviour and compatibility

This species is very peaceful indeed making it an ideal resident of the larger, well-furnished community tank. As it places no special demands in terms of wate…

Sexual dimorphism

Mature females are noticeably rounder-bellied and often a little larger than males.

Reproduction

This is one of the easier members of the genus to breed and like most cyprinids is an egg-scattering, continuous spawner that exhibits no parental care. That i…

Notes

This popular species is also known as the 'three-lined' rasbora and provided a large enough tank is available it is an excellent choice for those new to the ho…
