Etymology

Anostomus: from the Greek ano- (Gr. ἀνά-), meaning 'up, upward', and stóma (Gr. στόμα), meaning 'mouth', in reference to the upturned mouthparts possessed by m…

Distribution

This species is widely-distributed in the Río Orinoco system in Brazil, Colombia and Venezuela, plus coastal river drainages in Guyana, Suriname and French Gui…

Habitat

Typically found in rocky areas at the edge of fast-flowing stretches of rivers and streams where it grazes on algae and small invertebrates.

Aquarium size

A tank with base dimensions of 120 ∗ 30 cm or equivalent should be the smallest considered.

Maintenance

A biotope-style set-up could consist of a sandy substrate, piles of smooth rocks and driftwood roots and branches, some of which should penetrate the water sur…

Diet

Omnivorous but primarily a herbivore. Offer small live and frozen foods as well as plenty of vegetable matter in the form of blanched spinach, lettuce, cucumbe…

Behaviour and compatibility

Although it occurs in large shoals in nature, it tends to be very quarrelsome with conspecifics if only a few individuals are kept. It can be maintained in gro…

Anostomus currently contains five valid species though only A. anostomus and A. ternetzi are well-known in the aquarium hobby.

A phylogentic study by Sidlauskas and Vari (2008)[2] demonstrated the genus as recognised at the time to represent a polyphyletic lineage.

Three species, A. intermedius, A. plicatus and A. spiloclistron, were found to be more closely-related to the genera Gnathodolus, Sartor and Synaptolaemus than to other congeners and therefore placed into the new genus Petulanos, with P. plicatus as type species.

The family Anostomidae is distributed throughout much of tropical and subtropical South America from northwestern Colombia to central Argentina.

The majority of species are moderately-elongate and somewhat rounded in shape although there are some exceptions, e.g., the relatively deep-bodied Abramites.

Greater diversity is apparent in the range of oral morphology, however, and members exhibit a wide range of adaptations in dentition and jaw structure.

A number of anostomids tend to swim at an oblique 'head-down' angle which has given rise to them being referred to by the generalised vernacular term 'headstanders'.

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.
