Very peaceful and suitable for many community aquaria given its relatively small size. Good tankmates include other species that prefer hard water, such as similarly-sized rainbowfish, livebearers and freshwater gobies. In the brackish tank it can be combined with smaller, peaceful species such as mollies, halfbeaks, gobies etc.
Like some other rainbowfish it can be quite skittish and does far better when kept in a shoal of at least 6-8, preferably more. The males will also be encouraged to display their best colours in the company of conspecifics. Try to provide 2-3 females per male.
This rainbowfish is ideally suited to a heavily planted setup and will show its best colours in such surroundings. The use of floating plants to dim the light a little is also recommended. Allow open spaces between areas of planting to provide swimming space and areas for males to display at one another. High water quality is essential to the well-being of this species, so weekly partial water changes are recommended. Contrary to popular belief, it doesn’t require the addition of salt to its water, although it can tolerate mildly brackish conditions.
