Chaetodon Ephippium - The Saddleback Butterflyfish

Chaetodon Ephippium (The Saddleback Butterflyfish)

Native to the Indo-Pacific, commonly found in coral-rich reefs and lagoons.
Recognizable by its pale yellow body, large black saddle-like marking on the back, and a vibrant orange-red border along the dorsal and anal fins.
A relatively large butterflyfish species that is both active and inquisitive.
Often found in pairs in the wild, though it can also be observed swimming alone.
Best suited for a well-established marine aquarium with ample open swimming space and rock formations.

Omnivorous, feeding on a variety of invertebrates, algae, and coral polyps in the wild.
In captivity, it thrives on a diet consisting of sponge-based foods, high-quality pellets, frozen mysis shrimp, and marine algae.
May take time to adjust to prepared foods, so a gradual transition with a variety of offerings is recommended.
Providing multiple small meals per day supports digestion and prevents malnutrition.
A nutrient-rich and diverse diet helps maintain bright coloration and overall vitality.

Typically inhabits coral reefs with plenty of rocky structures and crevices for shelter.
Prefers moderate water flow and well-oxygenated conditions.
Aquarium setups should include live rock to provide natural grazing opportunities and hiding spots.
Maintaining excellent water quality is crucial for this species, as it is sensitive to poor conditions.
Providing a balance of shaded and open areas helps encourage natural behaviors.

Optimal water temperature: 74-82°F (23-28°C) to ensure healthy metabolism.
Preferred pH range: 8.1-8.4, with a salinity level of 1.020-1.025.
Requires regular water changes and high-quality filtration to maintain stable parameters.
Not considered fully reef-safe, as it may nip at soft corals and sessile invertebrates.
Providing a structured tank environment with live rock and ample swimming room helps reduce stress.

Generally peaceful but can be aggressive toward other butterflyfish if housed in a small tank.
Compatible with tangs, angelfish, and other semi-aggressive marine species.
Not fully reef-safe, as it has a tendency to feed on coral polyps and small invertebrates.
Should be housed with fish of similar size and temperament to prevent bullying or competition.
Providing ample swimming space and rock formations minimizes territorial disputes.

An active and social species that enjoys patrolling the aquarium.
Frequently observed picking at rock surfaces and interacting with tankmates.
May take time to fully acclimate but will become more confident as it settles in.
Providing live rock structures encourages natural grazing behaviors and creates a stimulating environment.
Over time, it may recognize its caretaker and display curiosity, especially during feeding times.
