Overview

Keep a shoal of six over sand in 75 liters with soft, warm water. It feeds on the standard sinking and frozen menu once settled, though fresh imports can be slow starters. Documented breeding is lacking. Rio Negro shipments bring it in modest numbers at best, so groups take patience to assemble.

In the wild

This cory lives in the Rio Icana, a blackwater tributary of the upper Rio Negro, over white sand and sunken leaves in warm, very soft water. Give it a blackwater-leaning tank: fine sand, litter, wood shade, and water at 24 to 28 degrees Celsius with pH 5.5 to 7.0.

Good to know

Warren Burgess described this species in 1993, and it holds a small piece of hobby history: it was the first cory catalogued under the C-number system, C1. The 2024 revision lists it as Brochis incolicana. Adults reach about 6 centimeters and wear a clean arc of dark pigment along the back half of the body.

Did you know

When German aquarists invented the C-number system for unidentified corys, this fish got the very first slot: C1.
