Chaetodon Ulietensis (The Pacific Double-Saddle Butterflyfish)

Overview

• Native to the Indo-Pacific, commonly found in coral reefs, lagoons, and shallow coastal waters.
• Characterized by its striking white body, bold black bands, and yellow dorsal and caudal fins.
• A moderately hardy species that adapts well to captivity with proper care and a stable environment.
• Often observed in pairs or small groups, particularly in coral-rich habitats.
• Best suited for an established aquarium with live rock structures and stable water parameters.

Feeding

• Omnivorous, feeding on coral polyps, algae, and small invertebrates in the wild.
• In captivity, it requires a varied diet including sponge-based foods, frozen mysis shrimp, and high-quality marine pellets.
• Readily adapts to prepared foods but benefits from a mix of live and frozen offerings.
• Multiple small feedings per day help sustain energy levels and digestion.
• A nutrient-rich diet ensures vibrant coloration and overall health.

Habitat

• Prefers coral-rich reef environments with moderate to strong water flow.
• Frequently found near reef edges and rocky formations where food is abundant.
• Aquarium setups should include live rock to encourage natural foraging and hiding places.
• Requires high-quality filtration and stable water conditions to thrive.
• Providing shaded areas and open swimming spaces allows for a comfortable environment.

Fish Care

• Optimal water temperature: 74-80°F (23-27°C) to support a healthy metabolism.
• Preferred pH range: 8.1-8.4, with a salinity level of 1.020-1.025.
• Requires consistent water quality with regular maintenance and water changes.
• Not fully reef-safe, as it may nip at corals and sessile invertebrates.
• Providing live rock enhances grazing opportunities and supports natural behaviors.

Compatibility

• Generally peaceful but may exhibit territorial tendencies toward other butterflyfish.
• Compatible with tangs, angelfish, and other semi-aggressive marine species.
• Not ideal for reef tanks due to its tendency to graze on coral polyps.
• Should be housed with similarly sized fish to prevent competition for food.
• Providing ample space and hiding areas minimizes territorial aggression.

Aquarium Behavior

• An active and inquisitive species that enjoys exploring its surroundings.
• Frequently seen grazing on rock surfaces and interacting with other fish.
• May take time to acclimate to captivity but becomes more confident with proper care.
• Providing live rock encourages natural foraging behavior and enhances environmental engagement.
• Over time, it may recognize its caretaker and show increased curiosity, especially during feeding sessions.
