Water parameters
Overview
The tailspot corydoras is recognized by the fine speckles on its pale gray–beige body and the large black blotch on the tail base; its scientific name also means "spotted tail." Adults are around 5 cm. The Guapore and hastatus corydoras also have a tail spot, but those two are smaller species that swim in midwater; caudimaculatus is stocky and a typical bottom-dwelling corydoras. It comes from the warm waters of the Guaporé basin.
Tank Setup
- At least 60 liters for a group of 6–10; a large footprint.
- Fine, rounded sand substrate; shaded corners with roots and plants.
- 22–27°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 food reaches the bottom; it cannot live on leftovers alone.
Behavior and Compatibility
A peaceful, social bottom dweller. It sifts the bottom in a group and leaves fish and shrimp alone.
Good companions: tetras, rasboras, dwarf cichlids, gouramis, otocinclus, shrimp, other corydoras.
Avoid: cichlids that claim the bottom, large predatory fish.
