Overview
Keep six over sand in 60 liters with brisk clean water. Feeding is standard sinking-and-frozen fare. Real punctatus reaches the trade only through infrequent Suriname exports, so confirm provenance before believing a label. Breeding reports for the true species are scarce.
In the wild
The true punctatus cory lives in the Suriname and Iracoubo river systems of the Guianas, over sand in clear forest creeks. Like other Guiana Shield corys it wants clean, flowing, oxygen-rich water: 23 to 27 degrees Celsius, pH 5.8 to 7.2, over fine sand with stones and wood.
Good to know
Bloch described Corydoras punctatus in 1794, making it one of the oldest names in the genus, and for two centuries much of the hobby applied it to the wrong fish: the common spotted corys of Peru sold as punctatus are usually other species. The genuine article is a Suriname endemic of about 6 centimeters with a dotted body and dorsal-fin flag.
Did you know
Odds are most fish ever sold as this species were something else; the real punctatus is a Suriname rarity wearing one of the genus's oldest names, coined in 1794.
