Julii Cory

The Julii Cory adds fine dark spotting and an attractive patterned body to the aquarium floor. These peaceful catfish spend much of their time investigating sand, resting near cover, and moving about with their companions.

• Recommended aquarium: A 30-gallon aquarium or a comparable tank with roughly 91 cm of length is recommended for a group.
• Group size: At least 6 of the same species or confirmed form.
• Temperature: 72–78°F (22–26°C).

Aquarium setup and care

Provide fine sand, clean sheltered resting areas, and a broad open feeding zone. Plants and smooth wood give the fish security. Keep the aquarium established and well filtered, with regular partial water changes.

Keep ammonia and nitrite at zero, perform regular partial water changes, and remove uneaten food. Corys require their own balanced diet; leftover food and algae are not sufficient.

Diet and feeding

Feed complete sinking catfish foods alongside small frozen or live foods such as daphnia, brine shrimp, or appropriately sized worms. Watch the group at feeding time to ensure each fish receives food.

Compatibility

Works well with small peaceful tetras, rasboras, and similarly gentle fish. Avoid predators, fin nippers, and territorial fish that guard the entire bottom. A group of matching Corys supports their natural social behavior.

Spotting alone is not a reliable guarantee of true Julii identification; pattern and appearance vary.
