Chaetodon Collare - The Collare Butterflyfish

Chaetodon Collare (The Collare Butterflyfish)

Native to the Indo-Pacific region, particularly found in reef slopes and lagoons.
Characterized by its rich brown body, contrasted with a white vertical band and a deep orange caudal fin.
A highly adaptable species that can acclimate well to a properly maintained aquarium.
Often found in pairs in the wild, exhibiting strong social bonds and synchronized swimming behavior.
Best suited for a well-established marine aquarium with ample rock formations and open swimming areas.

Omnivorous, feeding primarily on plankton, coral polyps, and small benthic invertebrates in the wild.
In captivity, it benefits from a diet rich in sponge-based foods, high-quality pellets, and frozen marine preparations.
May be hesitant to accept prepared foods initially, requiring a period of adaptation.
Providing multiple small meals per day supports digestion and overall health.
A nutrient-rich diet enhances its coloration and helps prevent deficiencies.

Commonly found in coral reef environments with plenty of shelter among rocky outcroppings.
Prefers moderate water movement and well-oxygenated conditions.
Aquarium setups should incorporate live rock to support natural grazing and provide security.
Maintaining high water quality is essential for long-term success with this species.
Providing both shaded and open areas allows the fish to feel comfortable and exhibit natural behaviors.

Optimal water temperature: 75-82°F (24-28°C) for maintaining health and activity levels.
Recommended pH range: 8.1-8.4, with a salinity level of 1.020-1.025.
Requires stable water parameters, necessitating frequent monitoring and maintenance.
Not considered completely reef-safe, as it may nip at certain coral species and small invertebrates.
Ensuring a structured tank environment with live rock and hiding places helps reduce stress.

Generally peaceful but can exhibit mild territorial behavior towards other butterflyfish.
Compatible with tangs, angelfish, and other non-aggressive reef species.
Not fully reef-safe due to its tendency to graze on soft corals and sessile invertebrates.
Should be housed with similarly sized fish that do not pose a threat or outcompete it for food.
Providing a spacious aquarium reduces stress and allows for natural social interactions.

An active swimmer that frequently roams the tank, exploring its surroundings.
Often seen grazing on rock surfaces and interacting with tankmates.
May take time to fully acclimate but will become more outgoing with consistent care.
Providing live rock encourages natural foraging and creates a more engaging environment.
With time, it may develop recognition of its caretaker and display curiosity during feeding times.
