Description
Super Two Lines Cory – Corydoras ornatus
Introduction:
The Super Two Lines Cory (Corydoras ornatus) is a stunning and peaceful species of Corydoras catfish native to the Amazon River basin in South America. Known for its distinctive black markings that run in two parallel lines along its body, this small and active species is a favorite among aquarium hobbyists. Reaching an adult size of about 2.5 inches (6 cm), the Super Two Lines Cory is an excellent choice for a community tank, as it is non-aggressive and helps keep the substrate clean by scavenging for leftover food.
1. Natural Habitat and Behavior
In the wild, the Super Two Lines Cory is found in the clear, slow-moving waters of the Amazon and Orinoco basins, where it inhabits sandy or muddy bottoms. This species prefers areas with plenty of hiding spots, such as plants, driftwood, and submerged rocks, which provide refuge from potential predators. As a bottom-dwelling fish, the Super Two Lines Cory is active during the day, often seen foraging for food in the substrate. Corydoras species are generally peaceful and social, often seen in groups in the wild, and the Super Two Lines Cory is no exception, thriving best in a group of at least 6 individuals.
2. Aquarium Setup
- Tank Size: A minimum of a 20-gallon (75 liters) tank is recommended for a group of Super Two Lines Corys. A larger tank will provide more space for them to forage and interact with one another.
- Substrate: Fine sand or smooth gravel is ideal, as Corydoras species have sensitive barbels and can be injured by sharp edges. A soft substrate also allows them to sift through it to search for food.
- Decor: These fish enjoy a well-planted aquarium with plenty of hiding spots. Adding driftwood, smooth rocks, and plants will create an environment where they feel secure. They also appreciate open areas to swim in the middle levels of the tank.
- Water Conditions:
- Temperature: 72–78°F (22–26°C)
- pH: 6.0–7.5
- Hardness: 4–12 dGH
- Water flow: Gentle to moderate water flow, as Corydoras prefer calm, low-current areas.
- Lighting: Moderate lighting is fine, but floating plants can be used to diffuse light, mimicking their natural environment in the wild.
3. Diet and Feeding
The Super Two Lines Cory is an omnivorous scavenger, primarily feeding on small invertebrates, detritus, and plant matter in its natural environment. In the aquarium, its diet can be easily managed with the following:
- Staple Diet: Sinking pellets designed for bottom feeders, as well as algae wafers, which cater to their omnivorous nature.
- Supplemental Foods: Offer occasional live or frozen foods such as bloodworms, brine shrimp, and daphnia to provide protein.
- Vegetable Matter: Blanched vegetables such as zucchini, spinach, and peas can also be offered to ensure a balanced diet.
- Feeding Schedule: Feed small amounts 2–3 times per day, ensuring that all food is consumed within a few hours to avoid water contamination.
4. Compatibility with Other Fish
The Super Two Lines Cory is an excellent community fish that gets along well with most peaceful species:
- Ideal Tank Mates: Suitable tank mates include other peaceful species such as tetras, rasboras, guppies, and other small catfish. Corydoras are social fish, so they do best when kept in groups of at least 6.
- Caution: Avoid aggressive or overly territorial fish, as these may stress the Corys.
- Social Behavior: This species is peaceful and prefers the company of its own kind. It will spend most of its time foraging in the substrate, and it’s often seen in groups, which helps reduce stress.
5. Common Challenges and Tips
- Water Quality: Like many Corydoras species, the Super Two Lines Cory is sensitive to poor water conditions. Regular water changes (20–30% weekly) and proper filtration are necessary to maintain clean water.
- Tank Maintenance: The soft substrate is essential to prevent injury to their barbels. Avoid rough or sharp decorations in the tank.
- Social Needs: This species is highly social and will thrive in groups. A solo Corydoras will be stressed and may become less active.
- Tank Setup: Ensure plenty of hiding spots to provide security, as Corydoras species can be shy and prefer to have shelter available.
Conclusion
The Super Two Lines Cory (Corydoras ornatus) is a beautiful and peaceful catfish that makes an excellent addition to community aquariums. Its striking markings, gentle nature, and social behavior make it a delightful fish to observe. With the right tank setup, diet, and companions, the Super Two Lines Cory will thrive and bring activity and charm to your aquarium.
