Ancistrus Xenocara Care Guide
(Clearfin Bristlenose Pleco)
Ancistrus xenocara, commonly referred to as the Clearfin Bristlenose Pleco, is a small, peaceful species of catfish native to the rivers of South America, particularly in the upper Orinoco River basin. Its distinctive bristles, manageable size, and algae-eating habits make it a popular choice for community aquariums.
Tank Requirements
- Tank Size:
- Minimum 20 gallons for a single specimen. For a breeding group or community tank, consider 30–40 gallons.
- Tank Setup:
- Substrate: Use fine sand or smooth gravel to protect their sensitive undersides.
- Decor: Provide caves, driftwood, and smooth rocks for hiding and grazing. Driftwood is particularly important as it mimics their natural habitat and aids in digestion.
- Plants: Hardy plants like Anubias, Java fern, and Amazon swords can be added.
- Lighting: Low to moderate lighting suits their natural preference for dim conditions.
- Water Flow:
- Gentle to moderate water movement, mimicking slow-moving river habitats.
Water Parameters
- Temperature: 72–79°F (22–26°C)
- pH: 6.5–7.5 (slightly acidic to neutral)
- Hardness: 4–12 dGH (soft to moderately hard water)
- Ammonia/Nitrite: 0 ppm; nitrates should be kept below 20 ppm.
- Water Changes: Perform weekly water changes of 20–30% to maintain pristine water conditions.
Diet
Ancistrus Xenocara is primarily herbivorous but benefits from a balanced diet:
- Staple Foods:
- High-quality sinking algae wafers or spirulina-based pellets.
- Vegetable Matter:
- Blanched zucchini, cucumber, spinach, and sweet potato are excellent dietary additions.
- Occasional Protein:
- Offer live or frozen foods like bloodworms, blackworms, or brine shrimp sparingly.
- Feeding Schedule:
- Feed once or twice daily, ensuring the food reaches the tank bottom.
Behavior and Compatibility
- Temperament:
- Peaceful and non-aggressive, making them ideal for community tanks.
- Tankmates:
- Compatible with small, peaceful fish such as tetras, rasboras, guppies, and Corydoras. Avoid aggressive or overly territorial species.
- Activity:
- Primarily nocturnal but can adapt to daytime activity in a well-established aquarium.
Breeding
Breeding Ancistrus xenocara in captivity is relatively easy with proper preparation:
- Breeding Tank:
- Use a separate tank or a well-maintained community tank with plenty of caves. Water should be slightly acidic (pH 6.5–7.0) and warm (77–80°F).
- Conditioning:
- Condition adults with a varied diet rich in vegetables and protein.
- Spawning Behavior:
- Males guard a cave where the female deposits eggs. Males will fan the eggs to oxygenate them until they hatch, typically within 4–6 days.
- Raising Fry:
- Fry are free-swimming after 2–3 days. Offer them crushed algae wafers, blanched vegetables, or finely powdered spirulina-based foods.
Common Challenges
- Barbel Health:
- Poor substrate or unclean water can lead to barbel infections. Use fine sand and maintain excellent water quality.
- Driftwood Requirement:
- Driftwood is essential for their digestive system. Ensure it is always available in the tank.
- Algae Misconception:
- While they eat algae, their diet should be supplemented with other foods to ensure proper nutrition.
Interesting Facts
- Males develop prominent bristles on their snouts as they mature, which are used to attract females and assert dominance.
- They are excellent algae eaters and can help control algae growth in community tanks.
- Ancistrus xenocara is highly adaptable and can thrive in a variety of freshwater setups when provided with the right care.
