Osteogaster venezuelana
A medium-sized corydoras whose flanks flush blue-green, traded as an especially strongly coloured member of the aeneus group. It is hardy, undemanding about water chemistry and can be shoaled in a tank with an 80cm footprint.
Osteogaster venezuelana is a callichthyid catfish reported from Venezuela whose nomenclature remains unsettled. FishBase treats the older name Corydoras venezuelanus as a synonym of Osteogaster aenea and gives it no page of its own, while the Catalog of Fishes recognises it as valid. Seriously Fish likewise states that confusion surrounds its identity, and the aquarium trade distinguishes it as a strongly blue-green form. Standard length is 7.5cm. It is easy to keep, tolerating 21-27C, pH 6.0-8.0 and 2-15dGH, with an 80 x 30cm base of about 72 litres as the minimum. Peaceful and gregarious, it should be kept in groups of at least 4-6. Breeding follows the usual corydoras method of two males per female with a 50-70 percent cool water change once females are gravid; eggs are laid on glass or fine-leaved plants. Because the name is unsettled, no IUCN assessment exists under this species name.
