Overview

October 16, 2026 · Suggest an edit

Rabaut's corydoras is recognized by its copper–orange body with a metallic sheen and the dark band running along the back from below the dorsal fin toward the tail base; because of this color it is called the "rusty cory" in English. In juveniles the pattern is sharper and more contrasting and softens with age. Adults are around 6 cm. Its former name is C. myersi. It can be confused with the similarly colored C. zygatus from the same region; their care is the same.
