Life Cycle ( anglais )

fourni par Fishbase
A prolific breeder. The courtship ritual is frenetic; several batches of about 20 eggs are spawned among submerged marginal vegetation during the course of about 30 minutes. The eggs sink, and hatch in about 36 hours. The free-swimming fry are very delicate and sensitive to water conditions.

Diagnostic Description ( anglais )

fourni par Fishbase
Rasboroides vaterifloris is distinguished from its congener R. nigromarginatus by the location of pelvic-fin origin which is midway between the pectoral-fin base and anal-fin origin (vs. closer to anal-fin origin), by having the dorsal margin of the operculum more or less straight (vs. with a deep indentation), and the dorsal profile of the head approximately straight (vs. slightly concave) behind the level of the eye in males. Males of R. vaterifloris can be diagnosed from those of R. nigromarginatus by having a greater interorbital width (29-33 % HL, vs. 17-22) and a greater internarial width (19-21 % HL, vs. 11-17), while females differ by having a greater anal-fin depth (23.5-24.8 % SL, vs. 17.4-22.7), a greater interorbital width (25-33 % HL, vs. 16-21), a greater caudal-peduncle depth (12.4-13.4 % SL, vs. 10.4-12.3) and a lesser caudal-peduncle length (18.6-21.2 % SL, vs. 21.1-25.0). It differs from R. pallidus and R. rohani by having the dorsal-fin origin 1 scale-width (vs. 3 scale-widths) behind the pelvic-fin origin and alesser body depth of 31.0-32.8 % SL (vs. 33.0-37.5 in R. pallidus and 33.3-40.0 in R. rohani) (Ref. 94541).

Perlmuttbärbling ( allemand )

fourni par wikipedia DE

Der Perlmuttbärbling (Rasboroides vaterifloris, Syn.: Rasbora vaterifloris, Rasbora nigromarginata) ist ein kleiner Süßwasserfisch, der endemisch in den Stromgebieten der Flüsse Kalu und Nilwala im südlichen Sri Lanka vorkommt.

Der Gattungsname Rasboroides wurde wegen der Ähnlichkeit der Art zur Gattung Rasbora gewählt, das Art-Epitheton vaterifloris setzt sich aus Vateria, dem Gattungsnamen eines immergrünen Baums auf Sri Lanka und „floris“ (für Blüte) zusammen und verweist auf die Ähnlichkeit der Färbung des Fisches mit der Blütenfarbe des Baums.

Merkmale

Der Perlmuttbärbling hat einen hochrückigen, seitlich abgeflachten Körper der eine Maximallänge von 4 cm erreicht. In der Färbung der Art unterscheiden sich verschiedene Populationen je nach Fundort. Sie kann orangefarben, intensiv rot oder blauviolett sein und bei auffallendem Licht prächtig perlmuttfarben schimmern. Der Bauch ist weißlich oder orange. Die Flossen sind gelblich, die basalen Teile von Rücken-, After- und Schwanzflosse sind rötlich. Männchen sind schlanker und intensiver gefärbt. Rücken-, After- und Bauchflossen sind bei ihnen etwas länger. Die Seitenlinie ist vollständig (vs. reduziert bei Trigonostigma). Die Afterflosse ist stark eingebuchtet. Ihre sechs geteilten Flossenstrahlen unterscheiden Rasboroides von Rasbora (fünf).

Lebensweise

Der Perlmuttbärbling lebt in von Bäumen beschatteten, klaren und kühlen Gebirgsbächen mit ruhiger Strömung und einem schluffigen Bodengrund, oft in Bereichen mit einer großen Menge von abgestorbenen Blättern im Wasser. Er ernährt sich vor allem von terrestrischen Insekten (Zweiflüglern und Käfern) – die in das Wasser fallen – sowie von Detritus.

Rasboroides vaterifloris ( anglais )

fourni par wikipedia EN

Rasboroides vaterifloris, known as the pearly rasbora, vateria flower rasbora or fire rasbora, is a species of freshwater cyprinid fish endemic to Sri Lanka. It can be found in the shallow waters of shaded, slow-flowing clear streams with a silt substrate. It also prefers areas with plentiful leaf debris. Its diet consists of detritus and terrestrial insects. This species can reach a length of 4 centimetres (1.6 in) TL. It can also be found in the aquarium trade.[2]

R. vaterifloris was formerly believed to be the only species in the genus and found in several river basins. A study in 2013 found that it was restricted to the Kalu River basin, with related species inhabiting other basins.[3] However, a comprehensive taxonomic review in 2018 based on morphometry, meristics and mtDNA found that one of the species recognized in 2013, R. nigromarginatus (also restricted to the Kalu River basin), is a junior synonym of R. vaterifloris.[4] Although this expands its range in the Kalu River basin, R. vaterifloris is more threatened than the relatively widespread R. pallidus.[4]
