The fish, up close
The Julii Cory, scientifically known as Corydoras julii, is a small and peaceful freshwater catfish species native to the tributaries of the Amazon River in South America. It has a distinctive pattern of black spots and stripes on a light beige or white background, resembling intricate hieroglyphs. Julii Cories have long barbels around their mouths, which they use to sift through the substrate in search of food. These social fish are best kept in groups of at least 6 individuals to thrive and exhibit their natural behaviours.
Care guide
Use these notes to shape a setup around the fish, then speak with our team about the tank you have in mind.
Plan your setupBehaviour
Julii Cories are peaceful bottom-dwellers that spend much of their time scavenging for food in the substrate. They are social and do best when kept in groups, displaying shoaling behaviour as they explore the tank together. These fish are active during the day and may become more active during the evening hours.
Tank planning
Maintaining good water quality is crucial for the health of Julii Cories. They prefer well-oxygenated water with a temperature between 22-26°C and a pH range of 6.5-7.5. Provide them with a sandy substrate to prevent injury to their delicate barbels. Regular water changes and a well-established tank with hiding spots, such as caves or plants, are important for their well-being.
