Water parameters
Overview
As its name says, the concolor corydoras is a "single-colored" corydoras: its body has no spots, bands or mask; it carries a plain color that shifts from gray to purplish depending on the light. This simplicity makes it easy to recognize among its spotted and striped relatives. Adults reach 5–6 cm. Coming from the Orinoco basin, this species is close to the bronze corydoras in its care needs and is hardy.
Tank Setup
- At least 60 liters for a group of 6–10; a large footprint.
- Fine, rounded sand substrate; a plain-colored fish stands out more over dark sand.
- 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. Make sure enough food reaches the bottom; corydoras cannot live on leftovers alone.
Behavior and Compatibility
A peaceful, calm bottom dweller. It sifts the bottom in a group and does not harm shrimp or small fish.
Good companions: tetras, rasboras, peaceful barbs, gouramis, dwarf cichlids, otocinclus, shrimp.
Avoid: cichlids that claim the bottom, large predatory fish.
