The Emerald Dwarf Rasbora (Celestichthys erythromicron) is a brilliantly patterned nano fish recognized for its metallic green body and vivid vertical striping. Often associated with high-elevation lake systems, this species delivers intense coloration and refined movement in planted freshwater aquariums.

This offering consists of Tank-Bred specimens, raised in controlled aquarium environments for improved adaptability and stability in captivity. Tank-bred Emerald Dwarf Rasboras acclimate well to established planted systems when provided stable parameters and structured aquascapes.

Ideal for nano community aquariums and carefully curated planted layouts, Celestichthys erythromicron thrives in well-maintained systems with moderate planting density and gentle flow.
