Etymology

Acestrorhynchus: from the Greek akéstra (Gr. ἀκέστρα), meaning 'darning needle' and rhýnchos (Gr. ῥύγχος), meaning 'snout', in reference to the presence of sha…

Distribution

The type series was collected from 'tributary of Rio dos Marmelos, Rio Madeira basin, 110 kilometers east of Humaitá along rodovia Transamazônica, Amazonas Sta…

Aquarium size

Acestrorhynchids are typically very active and extremely fast swimmers so minimum base dimensions in the region of 120 ∗ 45 cm are required even for a smaller …

Maintenance

The aquarium should ideally be designed to resemble a flowing stream or river with a substrate of variably-sized rocks, sand, fine gravel, and some larger wate…

Relatively peaceful with anything too large to swallow and can be maintained in a community provided tankmates are chosen with care.

Aggressively territorial or very competitive species should be avoided with the best choices being placid fishes such as Geophagus spp., Acarichthys heckelii, medium-sized doradid or loricariid catfishes and characids from genera like Ctenolucius, Mylossoma or Myloplus.

This species is not aggressive towards conspecifics with juveniles in particular exhibiting a marked schooling instinct.

Older individuals tend to be more solitary but still group together from time-to-time, and it's best maintained in numbers of four or more.

One important point to note is that acestrorhynchids are cannibalistic given the opportunity so if buying a group or adding to an existing school try to ensure that all individuals are of comparable size.

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

Sexual dimorphism

Sexually mature females tend to grow a little larger and be deeper-bodied than males.

Reproduction

Observations of the congener A. falcatus suggest that spawning occurs in midwater with the female remaining stationary while the male swims around her in a 'fi…

Notes

This species is a member of the putative 'A. nasutus group' of closely-related species within the genus alongside A. nasutus, A. maculipinna and A. falcirostri…
