Chaetodon Auriga (The Threadfin Butterflyfish)

Overview

• Native to the Indo-Pacific, including the Red Sea and eastern coasts of Africa.
• Easily recognized by its white body adorned with diagonal black stripes and a distinct black spot near the rear fin.
• A hardy and adaptable species that thrives in well-maintained aquariums.
• Generally peaceful but may display territorial behavior toward other butterflyfish.
• Requires a spacious marine aquarium with rock structures and open swimming areas.

Feeding

• Omnivorous, primarily consuming small crustaceans, coral polyps, and algae in the wild.
• Readily accepts high-quality marine pellets, frozen foods, and meaty seafood-based diets in captivity.
• Including sponge-based food in its diet enhances health and maintains bright coloration.
• Regular feeding throughout the day supports digestion and sustains energy levels.
• A well-balanced diet helps ensure a strong immune system and overall well-being.

Habitat

• Prefers coral-rich environments with ample rock formations for shelter.
• Thrives in moderate water movement with stable water parameters.
• Aquarium setups should feature live rock for natural foraging and enrichment.
• Requires a well-maintained marine system with clean, oxygenated water.
• Providing shaded areas and swimming space helps encourage natural behaviors.

Fish Care

• Ideal water temperature: 74-80°F (23-27°C) for optimal health.
• Recommended pH range: 8.1-8.4, with a salinity level of 1.020-1.025.
• Requires strong filtration and frequent water changes to maintain water clarity.
• Acclimating it to a mature aquarium reduces stress and promotes a healthy adjustment.
• Providing a structured environment with caves and crevices helps minimize territorial disputes.

Compatibility

• Generally peaceful, but may become aggressive toward other butterflyfish.
• Compatible with tangs, wrasses, and other similarly non-aggressive species.
• Not considered reef-safe, as it may nibble on corals and small invertebrates.
• Should not be housed with overly aggressive fish that could intimidate or outcompete it.
• Providing ample swimming space reduces stress and territorial behavior.

Aquarium Behavior

• An active and curious swimmer that explores rock formations frequently.
• Often seen foraging for food along rock surfaces and investigating its surroundings.
• May establish a territory but generally coexists well in larger tanks with diverse species.
• Providing a dynamic environment with live rock encourages natural feeding behaviors.
• Over time, it may become more interactive with its caretaker, especially during feeding times.
