Bronze corydoras

📖 Overview

Facultative air-breathing ; Found mostly in quiet, shallow waters with soft bottoms , but also inhabit running waters . Benthic . Adults stay in schools of 20 to 30 individuals. Because of their ability to breathe air intestinally, they take air 1 to 45 times per hour . Nocturnal . Adults feed on worms, crustaceans, insects and plant matter . Spawning occurs when the physical-chemical quality of the water changes with the onset of the rainy season . Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 60 cm .

🥚 Reproduction

During the spawning process, corys assume the so-called "T" position, with the male assuming the top part of the "T" and the femalae oriented perpendicular to him . The male stirs up the female with his barbels on her head and back; the female collects sperm in its mouth; lays down about 20 eggs (yellow in color, 1 mm in size) which she collects with her pelvic fins, then fertilizes them and fixes them to submerged rocks or plants. Such sequence takes place for 2-3 hours, thus resulting in spawning of 100-200 eggs. Several spawnings are possible in the same season. At 22°C, hatching occurs after 5 days, the vitellin being absorbed 3 days later .
