Threadfin rainbowfish
species of fish

The threadfin rainbowfish or featherfin rainbowfish (Iriatherina werneri) is a rainbowfish, the only species in the genus Iriatherina. It is characterized by long beautiful fins, and is among the most attractive of the rainbowfishes.
It is native to freshwater swamps and demersal or thickly vegetated areas of flowing waters, in tropical northern Australia and New Guinea.
It grows up to 5 cm (2.0 in) in length, but this does not include the Threadfin's long tail. Sexing is easy by examining fins: males have larger, gaudier finnage than females. Males also have more intense colours. When reproduction takes place eggs are scattered among the leaves of submerged vegetation, and hatch after 7–10 days.
The threadfin rainbowfish was described by Herman Meinkin in 1974 from types collected in Merauke, Irian Jaya, Indonesia. Meinken honoured the German aquarium fish trader Arthur Werner, who collected the type, in the specific name. The generic name is a combination of Iri referring to Irian Jaya and atherina, referring to the silverside genus Atherina as they were thought to be in the same family at the time of naming.

Why this record matters
“Threadfin rainbowfish” is worth following because a concise public description often conceals a longer documentary argument. Here, Threadfin, rainbowfish and species provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Oct 5, 2025. The linked authority identifier is Q2107345. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1974.
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.
