Chaetodon Meyeri (The Meyer’s Butterflyfish)

Overview

• Native to the Indo-Pacific, frequently found in coral reefs and lagoons with rich coral growth.
• Easily recognized by its elegant white body covered with black, maze-like lines and a distinctive yellow outline along its fins.
• A specialized species that requires a well-maintained aquarium with stable water conditions.
• Typically observed in pairs or small groups, often seen swimming close to branching corals.
• Best suited for experienced aquarists due to its delicate dietary needs and sensitivity to environmental changes.

Feeding

• Obligate corallivore, primarily feeding on coral polyps in the wild.
• In captivity, it requires a diet rich in sponge-based foods, frozen mysis shrimp, and high-quality marine algae.
• May be difficult to transition to prepared foods, so a slow introduction is recommended.
• Frequent small meals throughout the day help sustain energy levels and prevent malnutrition.
• A varied diet with enriched foods supports long-term health and vibrant coloration.

Habitat

• Prefers coral-dense reef environments with moderate water movement.
• Often found near reef slopes and sheltered coastal areas where food sources are abundant.
• Aquarium setups should include plenty of live rock to provide natural grazing opportunities.
• Requires pristine water conditions with high-quality filtration to maintain health.
• Providing shaded areas and open swimming space encourages natural behaviors and reduces stress.

Fish Care

• Optimal water temperature: 75-82°F (24-28°C) to support metabolic function.
• Preferred pH range: 8.1-8.4, with a salinity level of 1.020-1.025.
• Requires stable water parameters with frequent water changes and monitoring.
• Not considered reef-safe, as it actively feeds on live coral polyps.
• Providing live rock enhances foraging behavior and creates a more naturalistic environment.

Compatibility

• Generally peaceful but can be territorial towards similar butterflyfish species.
• Compatible with tangs, wrasses, and other non-aggressive marine fish.
• Not suitable for reef tanks due to its coral-dependent feeding habits.
• Should be housed with similarly sized fish that will not outcompete it for food.
• Providing adequate swimming space and well-defined territories helps minimize aggression.

Aquarium Behavior

• An active and graceful swimmer that enjoys patrolling the tank.
• Frequently observed picking at rock surfaces and searching for food.
• May take time to adjust to captivity but becomes more comfortable with stable conditions.
• Providing live rock encourages natural foraging and enhances activity levels.
• Over time, it may develop recognition of its caretaker and exhibit curiosity, especially during feeding sessions.
