Emerald-Eye Rasbora

The eyespot rasbora 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 reflected light, the fish sometimes displays a fine lateral band from the operculum 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. …

It 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

It is a typical rasbora with respect to breeding, namely it is a scatterer of non-adhesive eggs, choosing fine-leaved aquatic foliage as the repository for its eggs. However, success at the captive breeding of this species is heavily contingent upon water chemistry - the species is only likely to spawn in soft, acidic water matching that of its natural habitat, and thus particularly scrupulous attention to water chemistry is required if captive breeding is to be attempted. While as an additional measure to control water chemistry, filtration over peat is not vital, it is likely to be a contributory factor in success with this species (or, alternatively, the use of commercially available 'blackwater tonic' type products to condition the water accordingly). Once the matter of water chemistry has been settled, the breeding aquarium should be furnished with fine-leaved aquatic foliage. Cabomba and Myriophyllyum are suitable choices, and Java moss is likely to be a useful addition to the breeding aquarium as well. Synthetic substitutes can also be utilised if live plants are unavailable, or the requisite species are difficult to obtain. Prospective parents should be conditioned using live foods as described above, and introduced with some care to the breeding aquarium. …
