Overview
The Emerald Eye Rasbora is a slender, translucent little fish whose eyes shine iridescent green under the right light, with a bold black spot ringed in white on the dorsal fin. It comes from soft blackwater streams and peat swamps in Southeast Asia. Cheap, hardy and undemanding, it suits peaceful planted community tanks and nano set-ups alike.

- Habitat: Gently flowing blackwater streams linked to peat swamp forest
Feeding

- Preferred Foods: Daphnia, Artemia, cyclops, micro pellets, crushed flake, microworms
- Feeding Habits: Small feeds once or twice daily; live or frozen food daily is ideal for colour and breeding
Tank Mates

Aggression & Behaviour

- Territoriality: None; shoals tightly and shows best in numbers
Experience Level

Final Notes
Buy a group of at least eight; alone or in small numbers they hide and fade. Dim lighting, floating plants, leaf litter and a dark substrate make the green eyes really shine. It is an egg scattering continuous spawner with no parental care, and females are noticeably rounder in the belly. Once settled in a mature planted tank it is an undemanding and charming fish.
