Overview

The Guapore cory is a hardy little catfish and a good first cory.

Did you know

Most cories hug the bottom, but the Guapore cory forms loose groups that hover and swim well up in open water. It was even formally redescribed as a midwater member of the group.

Caring for the Guapore cory

Keep Guapore cories in a group of at least six so they behave naturally, in 16 gal (60 L) or larger. They feed along the bottom but spend a lot of time up in the water column. Give them open swimming space as well as a soft sand bed for foraging.

Add driftwood and shaded planting, and keep the water clean and well oxygenated with a gentle current. They are comfortable in a warm range of 72 to 82°F (22 to 28°C) and a pH of 6.0 to 7.5. Feed sinking pellets, wafers and frozen bloodworm and daphnia, making sure enough reaches the substrate.

Guapore cories are peaceful, so keep them with small, calm community fish. Regular aquarium spawning is not widely recorded. Like the rest of their group, they lay sticky eggs, and the female holds them briefly between her pelvic fins before attaching them.
