Etymology

Hyphessobrycon: from the Ancient Greek υπελάσσων (hyphesson), meaning 'of lesser stature', used as a prefix in this case, plus the generic name Brycon. herbert…

Distribution

This species appears to be widespread throughout the upper rio Paraguai in the states of Mato Grosso and Mato Grosso do Sul, Brazil, both north and south of th…

Appears to favour minor tributaries, headwater rivers, oxbows, and seasonally inundated floodplains.

For example, it has been collected from small streams draining to the upper rio Sepotuba in Mato Grosso state, itself a tributary of the upper rio Paraguai. These comprise flowing tributaries measuring a few metres wide with clear, light brown water and thick marginal vegetation. In some places aquatic macrophytes, including members of the genera Eleocharis, Echinodorus and Echinoria, also grow densely.

Sympatric fish species in the Sepotuba watershed include Astyanax assuncionensis, Creagrutus meridionalis, Knodus chapadae, Moenkhausia dichroura, Serrapinnus calliurus, Odontostilbe pequira, Pyrrhulina australis, Characidium aff. zebra, Leporinus friderici, Hoplias malabaricus, Farlowella paraguayensis, Rineloricaria cacerensis, Otocinclus sp., Corydoras aff. aeneus, Aequidens plagiozonatus, Crenicichla cf. lepidota, Gymnotus inaequilabiatus, Rivulus aff. picturatus, and Synbranchus marmoratus.

In the Pantanal small characids are often found in extremely clear water where submerged vegetation proliferates. The wetland is rich in aquatic macrophytes with at least 280 species recorded, including members of genera popular in the aquarium hobby such as Echinodorus, Bacopa, Ludwigia, Sagittaria, Eleocharis, and Salvinia.

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.

Aquarium size

An aquarium with base dimensions of 80 ∗ 30 cm or equivalent should be the smallest considered.

Maintenance

Perhaps looks best in an arrangement comprising a sandy substrate plus some driftwood roots and branches, or heavily-planted planted set-up. The addition of dr…

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 best-maintained alongside similarly-sized characids, gasteropelecids…

Sexual dimorphism

Sexually mature females are noticeably deeper-bodied and 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 has been a ubiquitous aquarium fish since its discovery, and is produced on a commercial basis in several countries, therefore wild fish are no lo…
