Overview

Did you know
Froehlich's cory is usually misspelled as froelichi, even by the shops that stock it. The original description spells it froehlichi, h and all, and that spelling has priority.
Caring for the Froehlich's cory
Keep Froehlich's cories in a group of six or more, in 20 gal (75 L) or larger. Give them a sand floor, some stones and a steady current, with clean water like the headwater streams they come from.
Keep the water at 72 to 79°F (22 to 26°C) and a pH of 6.0 to 7.5. Their Paraguay basin home means they tolerate cooler nights better than Amazon species. Feed sinking granules and frozen foods, which they take readily.
Froehlich's cories are peaceful and safe with other community fish. No aquarium breeding report has circulated yet.
