The Collare Butterfly (Chaetodon collare) is a striking marine fish known for its vivid colours and elegant shape. It reaches a maximum size of around 8 inches (20 cm), making it a moderately sized butterflyfish in the aquarium trade. Its body features a distinct colour pattern with a bright yellow base and a bold black collar, resembling a formal attire, which gives the fish its common name.


Belonging to the family Chaetodontidae, the Collare Butterfly is part of a group of reef-associated fish, known for their attractive patterns and vibrant hues. Genus Chaetodon encompasses various butterflyfish species, and the Collare Butterfly shares this genus with close relatives like the Raccoon Butterflyfish (Chaetodon lunula) and Saddleback Butterflyfish (Chaetodon falcula). The name “Chaetodon” originates from the Greek words “khaite,” meaning “mane,” and “odon,” meaning “tooth,” which alludes to their bristle-like teeth.

Natural Habitat

In its natural habitat, the Collare Butterfly thrives in the warm, clear waters of the Indo-Pacific, including the Red Sea, the Maldives, and the South Pacific. Typically, it inhabits coral-rich environments, particularly lagoon and seaward reefs. These locales are characterized by vibrant coral formations, providing the fish with both shelter and a diverse food source. The fish is often observed in pairs or small groups as they gracefully navigate the intricate coral structures.

Keeping Collare Butterfly Healthy:  

Maintaining the Collare Butterfly in an aquarium setting requires a moderate to advanced level of care. Their delicate nature necessitates attention to water quality, temperature, and diet. They are sensitive to fluctuations in water parameters, making stable conditions paramount for their well-being. A well-established reef tank with pristine water conditions is ideal.

Special Requirements and Feeding

To ensure the Collare Butterfly’s health, offer a diet consisting of a variety of live or frozen foods. They are primarily omnivores, with a preference for coral polyps and small invertebrates. Supplement their diet with high-quality marine flakes and pellets. It’s advisable to feed them multiple times a day to satisfy their grazing tendencies.

How Many Should I Keep

Keeping a single Collare Butterfly is generally recommended due to their territorial nature. If you intend to keep more than one, provide ample space and ensure they are introduced simultaneously to reduce aggression.

Lighting Preference

Collare Butterflies prefer moderate to high-intensity lighting. This is essential, as it not only promotes the health of any corals in the tank but also brings out the vibrant colours of the fish.

Suitable Tank Mates

When selecting tank mates, consider peaceful species like other butterflyfish, angelfish, and some smaller tangs. Avoid aggressive or territorial fish that may intimidate or harass the Collare Butterfly. Additionally, be cautious with large, carnivorous species that could view the Collare Butterfly as prey.

Reproduction in the Wild 

In the wild, Collare Butterfly (Chaetodon collare) reproduction is characterized by distinct courtship and spawning behaviours. Mating pairs are often seen engaging in intricate dance-like movements above coral formations in sheltered areas. During these courtship displays, the male and female Collare Butterflies synchronize their movements and engage in intimate contact to ensure successful fertilization. After the courtship rituals, the female releases her eggs, and the male fertilizes them in open water, where the fertilized eggs then drift with the currents.

Breeding Chaetodon collare

Breeding Collare Butterflies in captivity, although challenging, is possible with careful attention to the following aspects:

1) Set up: Create a controlled environment in a spacious and established reef aquarium. Maintain stable water conditions with temperature around 77-82°F (25-28°C) and a specific gravity of 1.020-1.025. Ensure the presence of suitable coral species where the fish can deposit their eggs.

2) Courtship/ Spawning: To initiate courtship and spawning, introduce a well-conditioned pair into the breeding tank. Observe their behaviour closely. The male will begin to display courtship rituals, including vibrant colour changes and intricate swimming patterns. Spawning occurs when the female releases her eggs while the male simultaneously releases sperm to fertilize them. These fertilized eggs will then float freely in the water.

3) Rearing: To rear Collare Butterfly fry successfully, move the fertilized eggs to a separate rearing tank. Maintain water quality with suitable temperature and salinity. Provide appropriate food for the newly hatched larvae, such as rotifers or copepods, and later transition them to brine shrimp nauplii. The fry should be kept in a well-lit and carefully controlled environment to support their growth.

Sexual Dimorphism

Sexual dimorphism in Collare Butterflies is minimal. Both males and females share the same striking yellow and black colouration, making it challenging to differentiate between the sexes based on appearance alone. The primary differences become evident during courtship and spawning behaviours, where the male takes on a more active role in initiating and participating in the process.


The Collare Butterfly Chaetodon collare is native to the Indo-Pacific region, where it can be found in various locales, including the Red Sea, the Maldives, and the South Pacific. These tropical waters are known for their rich coral reef ecosystems, which provide the ideal habitat for this species. While the Collare Butterfly can be found in the aquarium trade, the original wild fish comes from these biodiverse marine environments.


The Collare Butterfly, Chaetodon collare, displays fascinating reproductive behaviours in the wild, characterized by intricate courtship rituals and open water fertilization. In captivity, breeding can be achieved with careful setup, monitoring of courtship behaviours, and dedicated rearing of the fry. Their minimal sexual dimorphism and striking colouration make them an alluring species for both aquarium enthusiasts and those intrigued by the beauty of marine life.

Additionally, any losses of livestock will also be charged to you. Please be aware that the items you are ordering are living creatures – livestock. We kindly ask that you refrain from ordering livestock if you are unable to accommodate the possibility of a delayed delivery.

    These terms and conditions are a fundamental aspect of our policy. Our primary goal is to dissuade individuals who could react negatively to a delayed delivery and subsequently request order cancellations. It is of utmost importance to underscore that your order pertains to living creatures, not mere inanimate objects. In the event of an occasional delay, it is crucial that you respond in a rational and responsible manner, taking into account the welfare of the livestock. We kindly request that you refrain from placing an order for livestock if you tend to react strongly to such situations. By proceeding with the order of livestock, you indicate your acceptance and agreement to abide by these specified terms and conditions.
