Endemic to the rio Araguaia system, the major tributary of the rio Tocantins in central and western Brazil, although the full range of H. haraldschultzi within the drainage is unclear.

Type locality is 'Ilha do Bananal, Goiaz, Brazil', referring to Bananal Island, the largest fluvial island in the world which is formed from the bisection of the Araguaia in southwestern Tocantins state.

Post-bifurcation, the eastern arm of the river is often referred to as the rio Javaés and it is probable that the type series was collected there since the Javaés runs through a portion of Goiás state.

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

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

Habitat

Little information appears to exist but presumably inhabits minor tributaries, backwaters and oxbow lakes rather than main river channels. In the Araguaia drai…

Aquarium size

Aquarium base dimensions of at least 60 ∗ 30 cm or equivalent are suggested.

Maintenance

Perhaps looks best in an arrangement comprising a sandy substrate plus some driftwood roots and branches although it will also thrive in a planted set-up. Floa…

Diet

Likely to be omnivorous feeding on small invertebrates, crustacea, filamentous algae, fallen fruit and suchlike in nature. In aquaria it may survive on a diet …

Behaviour and compatibility

Very peaceful making it an ideal resident of the well-researched community aquarium. It is perhaps best-maintained alongside similarly-sized characids, gastero…

Sexual dimorphism

Sexually mature females are noticeably rounder-bodied and usually a little larger than males.

Reproduction

An egg-scattering free spawner exhibiting no parental care. When in good condition adults will spawn often and in a mature aquarium it is possible that small n…

Notes

This species is occasionally available in the aquarium trade, although usually as bycatch among shipments of other fishes. It is sometimes traded as H. sp. 'Ar…
