Overview
The pretty cory is a peaceful blackwater cory for the bottom of a warm community tank. It is a step up from the easiest cories.
Did you know
The pretty cory is found only in the Rio Purus system, which keeps it scarce in the hobby.
Caring for the pretty cory
Keep pretty cories in a group of six or more, in a tank of at least 24 gal (90 L). Give them soft sand in a shaded, tannin-stained tank.
They like warm, soft, acidic water, at 75 to 82°F (24 to 28°C) and a pH of 6.0 to 7.5. Feed sinking pellets and small frozen foods that reach the bottom.
Pretty cories are peaceful, so keep them with calm tank mates. Breeding males grow a very tall, sail-like dorsal fin with a pale, cream-white front ray. They are hard to breed.
Good to know
The pretty cory's scientific name means beautiful. The 2024 revision placed it in the genus Brochis, as Brochis pulchra. It is one of the larger, more sought-after blackwater cories.
In the wild
The pretty cory comes from the Rio Purus and its tributaries in Brazil, where it lives in warm, soft, tannin-stained blackwater. It forages over sand among leaf litter and roots.
