Water parameters
Overview
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.
Tank Setup
- At least 60 liters for a group of 6–10; a large footprint.
- Fine, rounded sand substrate; shaded areas with roots and plants.
- 22–26°C, soft to moderately hard, clean and well-oxygenated water.
- A 25–30% water change every week.
Diet
Sinking tablets and granules, frozen bloodworms, brine shrimp and daphnia. Feeding in the evening reduces competition with fast fish.
Behavior and Compatibility
A peaceful, social bottom dweller. It is bolder and more active in a large group; it does not harm fish or shrimp.
Good companions: tetras, rasboras, peaceful barbs, gouramis, dwarf cichlids, otocinclus, shrimp.
Avoid: cichlids that claim the bottom, large predatory fish.
