deskripsi pendek Kunci identifiaksi (pengenalan) | Morfologi | Morfometrik

duri punggung lunak (Keseluruhan (total)) : 10; Sirip dubur lunak: 8 - 9; vertebrata, bertulang belakang: 29. 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 a lesser 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).
Body shape (shape guide): fusiform / normal.

Biologi     Daftar kata (contoh epibenthic)

Occurs in shallow, cool, clear, quiet, heavily shaded forest streams, usually with a silty substrate and often in areas with a large amount of leaf debris in the water. Feeds on terrestrial insects (Diptera and Coleoptera, see Ref. 6469) and detritus. Males slimmer and brightly colored than females.

Siklus hidup dan perilaku kawin Kematangan | Reproduksi, perkembang biakan | Pemijahan | telur-telur | Fekunditas | Larva

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.
