Scientific Name Corydoras davidsandsi  Black, 1987
Common Names Sands' Cory
Panzerwels (Germany)
Type Locality Rio Unini, whitewater area of the Rio Negro, Brazil.
Pronunciation Kory DOOR ass - David SANDS eye
Etymology Cory = helmet, doras = skin. In this case it was incorrectly used to mean armour (cuirasse) instead of skin in allusion to the dual rows of plates that run along the flanks of this genus. Named for David Sands, the English aquarist behind the seminal 'catfishes of the world' books but who has not continued this output into the new millenium.

Size 60mm or 2.4" SL. Find near, nearer or same sized spp.
Identification Corydoras are identified by their twin rows of armour plates along the flanks and by having fewer than 10 dorsal fin rays. They are most commonly confused with the other genera in the sub-family, namely Brochis, Scleromystax and Aspidoras.

C. davidsandsi is similar to C. melini both fish have a black stripe running from the lower dorsal fin to the lower caudal fin just past the caudal peduncle. In C. davidsandsi the line splits above the caudal peduncle (best viewed from above) and in most other species it does not split. Additionally, aside from the vertical eye stripe and the aforementioned back stripe, the flanks of C. davidsandsi are without further pigment, differentiating it from C. melini.
Sexing Females are stouter, especially if viewed from above.

Feeding Flake food, tablets, frozen and live foods like worms etc.
Furniture Sandy bottom, wood and plants like java moss and java fern around the perimeter.
Compatibility A perfect citizen.
Suggested Tankmates Smaller South American characins, Apistogramma and other Corydoras.
Breeding Like other Corydoras; water changes can induce spawning (T-clinch). Adding a small powerfilter/powerhead to the tank can help trigger spawning. Eggs are laid on the tank sides, on driftwood, and in plants. Eggs are prone to fungus. Suggest keeping the eggs in a floating net in the tank containing the parent fish. Alternatively, Methylene Blue can be used. Fry are fed with microworms after the yolk sac has been used up (3-4 days).
