Corydoras Splendens

Datasheet

General Description

The Emerald 'Brochis' (Corydoras splendens) is a species that was formerly classified in the genus Brochis. It is distinguished by its mottled color pattern as juveniles and enlarged dorsal fin, sometimes traded as ‘hi-fin cory’. It belongs to the family Callichthyidae, known for 'armored' catfish due to bony plates instead of scales. Corydoras are facultative air breathers, occasionally rising to the water surface to gulp air.

Aquarium Setup

For optimal care, a tank setup of at least 270 litres is recommended (see table). A sandy substrate or clean gravel is suitable, with added decor for security. Water conditions should ideally maintain a pH of 5.0-8.0, hardness of 36-268 ppm, and a temperature range of 20-28°C.

Behaviour

Emerald 'Brochis' are peaceful and sociable fish that thrive in groups of 6-8 individuals. They tend to form aggregations in smaller tributaries and still bodies of water. Their facultative air-breathing ability aids survival in oxygen-deprived environments, showcasing occasional surface gulping behavior.

Feeding and Diet

Corydoras splendens are omnivores, accepting sinking dried foods, live, and frozen varieties like bloodworms and Tubifex. A varied diet is essential for their well-being, as they should not solely rely on leftovers from other aquarium inhabitants for sustenance.

Reproduction & Dimorphism

Adult females of this species are rounder, taller-bodied, and slightly larger than males. Reproduction involves laying eggs near the water surface, facilitating easy removal for hatching and raising elsewhere.

Habitat and Distribution

The Emerald 'Brochis' is widely distributed throughout the Amazon basin in countries such as Brazil, Peru, Ecuador, and Colombia. They thrive in backwaters, oxbows, and marginal lakes, forming groups in these habitats.
