Brevibora dorsiocellata (Duncker, 1904) |
|
Brevibora dorsiocellata is a small fish belonging to the Family Cyprinidae, subfamily Danioninae, which is known by the common names of ocellated rasbora, hi-spot rasbora, and eye-spot rasbora, an allusion to the marking situated upon the dorsal fin. This small fish is a popular aquarium fish, having been one of the species featured in the landmark textbook Exotic Aquarium Fishes by Dr William T. Innes (page 180.1 - see References below). Its appearance in this work only occurs in later editions of the book, however, therefore the species is not subject to the same degree of aquarium domestication as the more familiar Harlequin rasbora.
Brevibora dorsiocellata is a native of Malaysia and Sumatra . It is an inhabitant of streams and other waterbodies with an acidic pH, at least some of these being situated in habitats classified as peat swamp forests (more details covered in the Habitat section below). or they found in National water resources
Brevibora dorsiocellata is an elongate fish, with a pointed snout, whose base colour is a reflective, metallic silver, though under some lighting conditions, the fish can take on a yellowish hue, with a slight pink flush present in the ventral area of the body between the operculum and the pelvic fins (corresponding roughly to the sac enclosing the alimentary canal). Under conditions of reflectied light, the fish sometimes displays a fine lateral band from the opeculum to the end of the caudal peduncle (Walker, 1971, p. 98) this being an olive-gold hue. The fins, with the exception of the dorsal fin, are hyaline, the relation of the pectoral and pelvic fins being typical of the ostariophysans (fishes possessing an auxiliary mechanism for detecting sound consisting of a set of internal bones called the Weberian Ossicles). In such fishes, the pectoral fins are located immediately behind the operculum, whilst the pelvic fins are located further back upon the ventral side of the body - in the case of Brevibora dorsiocellata, their position is to be found vertically beneath the dorsal fin. The dorsal fin is positioned approximately equidistant between the operculum and the caudal fin, and it is the marking upon this fin that gives rise to the common names of the fish: the base colour is white, with a large rounded black oval overlaid upon the base colour, in appearance fancifully likened to an eye.
