[1] The specific epithet hastatus means with a spear, in reference to the spearhead-like spot on the tail root.

Its body is a translucent white to olive color, with a thin dark stripe on the sides from behind the gill cover to the root of the tail, and a whitish belly.

[1] It feeds on worms, benthic crustaceans, insects, and plant matter.

Other Corydoras species with similar mid-water habits include C. habrosus and C. pygmaeus.

The female holds a single egg between her pelvic fins, where the male fertilizes them for about 30 seconds.

The pair repeats this process about every three minutes for from one to two hours with some 10- to 15-minute rests between egg releases.

A total of 30 to 60 eggs may be spawned by a single female over this period of time.

The aquarium should be clean, well-aerated, and densely planted to provide hiding places.

Although the fish is generally a mid-water dweller, a fine gravel or sand substrate should be provided since it will occasionally burrow.

Fish should be conditioned with large amounts of live foods such as Tubifex and whiteworms, during which time the females will become noticeably plumper.
