Corydoras Stenocephalus Care Guide
The Corydoras Stenocephalus, a species of catfish native to South America, is a peaceful and hardy species commonly referred to as a “Cory.” Known for its unique appearance, characterized by a long, narrow head and an elongated body, this species makes an excellent addition to community aquariums. As a member of the Corydoras genus, they are known for their playful nature and their ability to help keep the tank substrate clean by scavenging for food.
Tank Requirements
- Tank Size:
- A minimum of 20 gallons is suitable for a small group (6 or more is recommended).
- Larger groups or community tanks will require at least 30 gallons.
- Tank Setup:
- Soft, fine gravel or sand substrate is ideal for their sensitive barbels.
- Provide ample hiding spots using rocks, driftwood, and plants.
- A planted tank with a variety of hiding places and open swimming space is best.
- Lighting: Moderate; they prefer a dim environment with shaded areas to feel secure.
- Water Flow: Gentle flow, as these catfish prefer slow-moving waters.
Water Parameters
- Temperature: 72–79°F (22–26°C)
- pH: 6.0–7.5 (neutral to slightly acidic)
- Hardness: Soft to moderately hard (2–12 dGH)
- Ammonia/Nitrite: 0 ppm; nitrates should be kept under 20 ppm.
- Water Changes: Weekly water changes of 20–30% are important to maintain water quality and prevent the buildup of toxins.
Diet
Corydoras Stenocephalus is an omnivorous scavenger:
- Staple Foods:
- High-quality sinking pellets or wafers designed for bottom feeders.
- Live/Frozen Foods:
- Bloodworms, brine shrimp, daphnia, and tubifex worms.
- Vegetables:
- Offer blanched zucchini, spinach, peas, or algae wafers occasionally.
- Feeding Schedule: Feed once or twice a day, offering small amounts of food that can be consumed in a few minutes.
Behavior and Compatibility
- Temperament:
- Peaceful and social; Corydoras stenocephalus is best kept in groups of at least 6 to 8 individuals to reduce stress and promote natural behaviors.
- They are bottom-dwelling fish, scavenging for food and interacting with other members of their group.
- Tankmates:
- Compatible with a wide variety of peaceful species such as tetras, small gouramis, peaceful cichlids, and livebearers.
- Avoid housing with aggressive fish or very small fish that might be eaten.
- Activity Level:
- Active during the day, especially when there is food available. They enjoy exploring the bottom of the tank and foraging for scraps.
Breeding
Breeding Corydoras Stenocephalus can be accomplished in a well-maintained aquarium:
- Breeding Setup:
- A separate breeding tank with soft, slightly acidic water (pH 6.0–6.5) and a temperature of around 76–78°F is ideal.
- Provide flat surfaces such as broad-leaved plants or glass for egg-laying.
- Spawning Behavior:
- A successful breeding group will often spawn after a period of conditioning with high-quality food.
- Females will lay eggs on the surfaces, which are fertilized by the males.
- Egg Care:
- The eggs will hatch in 3–5 days, and the fry will be free-swimming within 1 week.
- Fry Care:
- Feed fry with infusoria or liquid fry food until they are large enough to eat baby brine shrimp.
Common Challenges
- Water Quality:
- Corydoras Stenocephalus is sensitive to poor water quality, especially high nitrate levels, so regular maintenance is critical.
- Barbel Damage:
- Their sensitive barbels can be injured by rough or sharp substrates, so it’s important to provide a soft substrate like sand or fine gravel.
- Overfeeding:
- Overfeeding can cause water quality issues and lead to obesity in these catfish, so be sure to offer small portions that they can eat within a few minutes.
- Stress in Small Groups:
- Keeping fewer than 6 individuals can cause stress and abnormal behavior. Ensure they are kept in groups to keep them comfortable and active.
Interesting Facts
- Like many other Corydoras species, Corydoras stenocephalus “sifts” through the substrate for food, which helps keep the tank clean.
- They are often referred to as “dwarf” or “petite” Corys due to their smaller size compared to other species in the genus.
- Their active, social nature and peaceful disposition make them a great choice for community tanks.
