Emerald Eye Rasbora Care Guide
Brevibora dorsiocellata · Freshwater Fish
What Emerald Eye Rasbora look like
The Emerald Eye Rasbora (Brevibora dorsiocellata) exhibits a slender, fusiform body that typically reaches a maximum adult size of approximately 1.5 to 2 inches (3.8 to 5 cm). This species is characterized by its striking emerald-green iridescent spot located on the upper body, just anterior to the dorsal fin, which serves as a key identifying feature. The body coloration is predominantly silvery with a subtle sheen, complemented by the distinctive greenish iridescent eyes that further enhance its visual appeal. The fish possesses a small, terminal mouth with fine, comb-like teeth adapted for grazing on microalgae and small invertebrates. The dorsal fin is moderately sized and situated towards the rear of the body, while the anal fin is elongated, contributing to its agile swimming capabilities. Notably, the Emerald Eye Rasbora lacks significant sexual dimorphism, though females may appear slightly fuller-bodied during breeding periods. Defensive adaptations include a laterally compressed body shape that allows for quick evasive maneuvers in the presence of predators.
Behavior & temperament
Emerald Eye Rasboras are inherently social fish, often found in small to medium-sized schools within their natural habitats. They primarily inhabit the mid to upper water column, displaying pelagic tendencies. Their behavior is characterized by a peaceful temperament, making them suitable for community tanks. During breeding, they exhibit egg-scattering behavior, where females release adhesive eggs among aquatic vegetation, which provides cover for the developing embryos. The social hierarchy within schools is relatively egalitarian, with no pronounced dominance behaviors observed. These fish thrive in well-planted environments that mimic their natural habitats, where they can engage in foraging and schooling activities.
Diet & feeding
In the wild, the Emerald Eye Rasbora is an omnivore, feeding on a varied diet that includes small invertebrates, zooplankton, and microalgae. In captivity, they require a balanced diet consisting of high-quality flake food, supplemented with live or frozen foods such as daphnia, brine shrimp, and finely chopped vegetables to ensure optimal health and coloration.
