Description: The base color of Corydoras melanistius is light grey, and the body is covered with small dark spots. There is a prominent black band across the head, extending down through the eyes, and another black patch on the back, extending into the dorsal fin.

After a cold water change that drops the temperature from 22-24 to around 16-18 degrees, the fish usually spawn in the typical T-formation. The female holds 2-4 eggs between her pelvic fins, where the male fertilizes them. Then the female swims to a suitable spot, where she attaches the very sticky eggs. The approximately 2 mm large eggs take 3-4 days to hatch, and after another 2 days, the young fishes are swimming free. You can raise them with micro eels and baby brine shrimp.
