Chalceus és un gènere de peixos de la família dels caràcids i de l'ordre dels caraciformes.[2]
Chalceus ist eine Gattung großer, schlanker Salmler aus Südamerika. Chalceus-Arten kommen im tropischen Südamerika östlich der Anden im Stromgebiet des Amazonas und in Guayana vor.
Chalceus-Arten werden 20 bis 25 Zentimeter lang. Ihr Körper ist langgestreckt, die große Schwanzflosse tief gegabelt, mit einem unteren Schwanzlossenlobus, der oft etwas größer ist. Auffälligstes Gattungkennzeichen ist die besondere Beschuppung. Oberhalb der Seitenlinie, die relativ tief an den Seiten liegt, gibt es drei Reihen sehr großer Schuppen, unterhalb sind die Schuppen sehr viel kleiner und zahlreicher. Im deutschen werden die Süßwasserfische auch Glanzsalmler oder Südamerikanische Großschuppensalmler (vgl. Afrikanischer Großschuppensalmler) genannt. Die Rückenflosse ist kurz und liegt hinter der Körpermitte. Eine kurze Fettflosse ist vorhanden.
Chalceus-Arten sind schnell schwimmende und gut springende Schwarmfische, die sich carnivor von kleineren Fischen und Insekten ernähren.
Chalceus wurde bis vor kurzem der Familie der Echten Salmlern (Characidae) zugeordnet und wurde dort in keine Unterfamilie gestellt (Incertae sedis). Im Jahr 2011 wurde die Gattung in eine selbständige, monotypische Familie gestellt, die Chalceidae (Claudio Oliveira et al., 2011).
Chalceus-Arten werden lokal als Speisefische genützt.

Chalceus is a genus of fish that inhabits freshwater habitats in South America. Members can be found in the Amazon and Orinoco basins, as well as in the Guianas and various tributaries of the former.[1] It is the sole representative of the family Chalceidae.
Members of the genus Chalceus typically reach a length of 15–25 cm (6–10 in), but are up to about 30 cm (12 in).[2] They have an elongated shape, and relatively large scales. Their fins are a variety of colors, most commonly red, yellow, or hyaline, with a red or pink tail being the most common.[3]
Chalceus was previously classified as a member of the family Characidae, and is still listed there by some authorities (like GBIF and ITIS).[4] However, recent phylogenetic and morphological analysis has prompted a move into the family Chalceidae, which is currently home only to the genus Chalceus (making it monotypic).[5][6] This move was also done in order to keep the family Charadicae monophyletic.[5]
Currently, there are five accepted species in the genus Chalceus.[2][7] In alphabetical order, they are:
The genus Chalceus was established by Georges Cuvier in the year 1818 when he described the pinktail chalceus (C. marcolepidotus) as a new species in a new genus.[8] By way of monotypy, the pinktail became the type species therein.[7] The next established species was the tucan fish, C. erythrurus, which was named by Edward Drinker Cope in 1870, though he first classified it in the genus Plethodectes with the full name Plethodectes erythrurus.[9] In 1872, he moved it to Chalceus.[10]
A full redescription of the genus occurred in the year 2004, undertaken by Brazilian biologists Angela M. Zanata and Mônica Toledo-Piza, which resulted in the nomination of the other three species.[11]
The name Chalceus is Greek in origin and comes from the word chalkos, which means copper.[12][13] This was given by Cuvier because he observed that the original specimen's scales were "sometimes golden" when preserved in alcohol.[8][14]

Chalceus est un genre de poissons téléostéens de la famille des "Characidae" en incertae sedis et de l'ordre des Characiformes. Les Chalceus se rencontre en Amérique du Sud, de l'Orénoque au bassin de l'Amazone, ainsi que les rivières des Guyanes. Ils atteignent généralement une longueur de 20-25 cm (7/9 à 9/8 po). Ce sont des prédateurs, se nourrissant d'insectes, de petits poissons, et similaires.
