Etymology

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

Distribution

Known only from a small area within the rio Preto and rio Maraca drainages in Amapá state, northeastern Brazil. Type locality (translated from German) is 'Smal…

Habitat

Collected from small streams flowing through savanna grassland containing clear, light brown-coloured water with substrates of sand and gravel and little in th…

Aquarium size

An aquarium with base dimensions of 60 ∗ 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 although it should also thrive in a planted set-up. Th…

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.

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 numbers of fry may start to appear without intervention, but if you want to maximise yield a more controlled approach is required.

The adult group can still be conditioned together but a smaller aquarium should also be set up and filled with mature water. This should be very dimly lit and the base covered with some kind of mesh of a large enough grade so that the eggs can fall through but small enough so that the adults cannot reach them. The widely available plastic 'grass'-type matting can also be used and works well, as does a layer of glass marbles. Alternatively, filling much of the tank with a fine-leaved plant such as Taxiphyllum spp. or spawning mops can also return decent results.

The water itself should be of slightly acidic to neutral pH with a temperature towards the upper end of the range suggested above. An air-powered sponge filter or air stone(s) should also be included to provide oxygenation and water movement.

When the adult fish are well-conditioned a single pair or group comprising one or two males and several females can then be introduced to each container and left in place until eggs are detected (typically the following morning).

Initial food should be Paramecium or a proprietary dry food of sufficiently small (5-50 micron) grade, introducing Artemia nauplii, microworm, etc., once the fry are large enough to accept them.

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.

Notes

This species is sometimes referred to as 'red line', 'scarlet', or 'neon black red stripe' tetra. It is very similar to the flag tetra, H. heterorhabdus, which…
