Overview

Fuller's cory is a peaceful bottom catfish that suits a community tank and a keeper with a little experience.

Did you know

Fuller's cory is named for Ian Fuller, the British catfish specialist whose CW numbering system cataloged unnamed cories. It wore his code, CW051, before it wore his name.

Caring for the Fuller's cory

Keep Fuller's cories in a group of six or more, in 20 gal (75 L) or larger. Long-snouted cories dig enthusiastically, so give them a deep bed of fine sand to root in. Add some wood and a patch of leaves.

Keep the water well oxygenated, at 73 to 81°F (23 to 27°C) and a pH of 5.8 to 7.2. Feed sinking prepared foods and frozen fare.

Fuller's cories are peaceful and get along with other community fish. Dedicated cory keepers have bred them using cool, soft water changes. Breeding them is hard, and they remain a project fish rather than a beginner spawner.

Good to know

Fuller's cory was described in 2021 by Tencatt and colleagues. It is a long-snouted member of the family Callichthyidae, and it keeps its place in the strict-sense genus Corydoras after the 2024 revision.

In the wild

Fuller's cory comes from the Madre de Dios drainage in southeastern Peru. It works the sandy runs and litter pockets of clear and lightly stained streams.
