Sailfin corydoras
species of fish
The sailfin corydoras (Scleromystax macropterus), bigfin corydoras, or largefin corydoras is a subtropical freshwater fish belonging to the Corydoradinae sub-family of the family Callichthyidae. It originates in coastal rivers in South America, and is found from São Paulo to Santa Catarina, Brazil and some upper Paraná River tributaries. It was originally described, under the name Corydoras macropterus, by Charles Tate Regan in 1913.
The fish will grow in length up to 3.4 inches (8.7 centimeters). It lives in a subtropical climate in water with a 6.0 – 8.0 pH, a water hardness of 2 – 25 dGH, and a temperature range of 64 – 70 °F (18 – 21 °C). It feeds on worms, benthic crustaceans, insects, and plant matter. It lays eggs in dense vegetation and adults do not guard the eggs.
The sailfin corydoras is of commercial importance in the aquarium trade industry.
This brief starts where responsible research should: with the source description of “Sailfin corydoras” as species of fish. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of fish. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jul 29, 2026. The linked authority identifier is Q3764460. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1913.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
