It’s very peaceful, but doesn’t make an ideal community fish due to its small adult size. It’s easily intimidated by larger tank mates and won’t compete well for food with them. Many fish often kept in community aquaria, such as angelfish, gouramis and larger catfish will also find it an ideal snack. Keep it alone or in a community of other tiny species, such as similarly sized characins, cyprinids or perhaps some small freshwater shrimp. It also makes an ideal dither species for Apistogramma and other dwarf cichlids, as it tends to inhabit the middle levels of the tank.
It lives in groups in nature so it’s best to buy at least 6, preferably 10 or more. You’ll find they shoal quite tightly, have more confidence and look much more effective when maintained in good numbers. They’ll also school quite happily with other small fish in the tank.
Like most corys, it’s easily sexed when viewed from above. Females are noticeably rounder and broader bodied than males, especially when full of eggs. They’re often also slightly larger.
