Overview

The Julii cory is a spotted catfish that forages in peaceful groups across the floor of a community tank. It is manageable for a keeper with some experience.

Did you know

The true Julii cory is rarely imported. Almost every fish sold under its name is really the three line cory, Corydoras trilineatus.

Caring for the Julii cory

Keep Julii cories in a group of at least six, in a tank of 20 gal (75 L) or larger. Give them a soft sand bed to sift, with driftwood, dried leaves and shaded planting.

Keep the water clean and gently filtered, at 68 to 79°F (20 to 26°C) and a pH of 6.0 to 7.5. Regular water changes keep this delicate cory in good condition.

Feed sinking pellets, frozen bloodworm and daphnia, and a little wafer. Julii cories forage across the sandy bottom with their barbels, so check that the food settles where they can reach it.

They mix well with small, calm community fish that leave the floor clear at feeding time. Julii cories have been bred in aquaria, but breeding them is rated difficult.

Good to know

The Julii cory is an armored catfish of the family Callichthyidae, listed as Hoplisoma julii and also known as Corydoras julii. It wears fine, separate dark spots on the head. The three line cory shows the same marks joined into maze like lines.

In the wild

The true Julii cory comes from clear coastal rivers in northeastern Brazil. It lives over sand in warm, soft, slightly acidic water.
