Description

• Size: Usually grows to about 4-5 cm (1.5-2 inches).
• Coloration: They have a light-colored body, typically silver or cream, with two distinctive horizontal dark lines running along each side of their body. This feature gives them the nickname “Super 2 Lines.”
• Body Shape: Like other Corydoras species, they have a rounded body with a slightly flattened belly and whisker-like barbels around the mouth, which they use for foraging.
• Fins: Their fins are typically clear or lightly colored.

• Temperament: Peaceful and social, Corydoras ornatus do well in groups (shoaling fish), and it’s recommended to keep at least 5-6 of them together in an aquarium.
• Activity: They are bottom-dwellers, often seen searching for food in the substrate with their barbels.

• Tank Size: A minimum tank size of 20 gallons is recommended for a small group.
• Water Parameters:
  • Temperature: 22-26°C (72-79°F)
  • pH: 6.0-7.5 (slightly acidic to neutral)
  • Hardness: Soft to moderately hard water
• Substrate: Soft, sandy substrate is ideal to protect their sensitive barbels from injury.
• Filtration and Aeration: Moderate water flow and good filtration are important to maintain water quality. They prefer well-oxygenated water.
• Plants and Décor: They appreciate live plants, driftwood, and hiding spots to mimic their natural habitat.

Corydoras ornatus are omnivorous, primarily scavengers. In an aquarium, they can be fed a varied diet that includes:

• High-quality sinking pellets or tablets
• Frozen or live foods like bloodworms, brine shrimp, and daphnia
• Blanched vegetables (e.g., zucchini or cucumber slices)

• Breeding Corydoras can be relatively easy in well-maintained aquariums.
• Spawning Behavior: They typically lay eggs on flat surfaces like leaves or tank walls. A conditioned pair or group of Corydoras can be stimulated to breed with water changes and feeding live or high-protein foods.
• After spawning, it’s best to remove the adults to prevent them from eating the eggs.

This species is a great choice for beginner and experienced aquarists alike due to its hardy nature and peaceful disposition.
