About the Species
Native to South America, Hoplisoma trilineatum is a peaceful, social bottom-dweller that naturally thrives in groups. Their unique patterning — made up of interconnected lines and markings — gives them a more complex look compared to spotted Cory species.
This species is often mislabeled as “Julii Cory,” but the difference lies in the pattern — with False Juliis showing a more maze-like, flowing design rather than simple spots.

False Julii Corydoras display a light base color covered in intricate dark patterning.
• Adult Size: 2–2.5 inches
• Body Type: Streamlined, armored catfish

False Julii Corydoras are extremely peaceful and thrive in groups.
