Corydoras paleatus is a species of catfish (order Siluriformes) of the family Callichthyidae.

[2] Corydoras paleatus is found in the Amazon basin,[1] and feeds on worms, crustaceans, insects, and plant matter.

[2] Charles Darwin discovered the C. paleatus when he went to Buenos Aires during his expedition aboard the Beagle during the 1830s.

Diet should be sinking pellets, algae wafers, frozen and live food, such as bloodworm or daphnia.

They may also occasionally enjoy blanched spinach, which can be attached to plants with a peg or the side of the glass with magnetic clips.

They can be seen to dart to the top of the tank: this is because they can use atmospheric oxygen to supplement what their gills extract from the water.

[citation needed] The males initiate the courtship ritual, which entails chasing the females around the tank.

Favorite spots include the heater, filters, and the glass, although, occasionally eggs are also laid on plants and driftwood.

In one study, the average hatching ratio of the eggs was found to be approximately 87%, with the overall egg-laying period lasting between 20 and 35 days[citation needed].

At first, the fry is small (with a mean length of 7.5246 mm[citation needed]) and is unable to eat, sustaining themselves on the last of their yolk sacs.
