Chaetodon flavirostris

Datasheet

General Description

The Black Butterflyfish, scientifically known as Chaetodon flavirostris, belongs to the Chaetodontidae family and is characterized by its attractive patterns and colors. They are part of a group of Butterflyfish known for their resemblance within a complex, with slight variations in color and patterns that are crucial to differentiate due to varying needs among species.

Aquarium Suitability

Being a docile species, the Black Butterflyfish is suitable for aquariums with caution. They thrive best when kept as a pair, ideally one male and one female, and require ample hiding spots among live rocks for security. Although initially finicky eaters, they eventually accept a varied diet, including small crustaceans and zooplankton. Furthermore, these fish need a spacious tank to allow for swimming and should be monitored for sensitivity during transportation and acclimatization.

Care and Hardiness

With average hardiness, the Black Butterflyfish demands a tank size of at least 500 liters, with water conditions featuring a pH range of 8.1-8.4, a specific gravity of 1.020-1.025, and temperatures between 22.2-25.6°C. They are known to be sensitive during transportation but can adapt well with proper care and attention.

Reef Suitability

Considered reef-safe with some luck, the Black Butterflyfish can coexist in a reef environment as long as they are provided with suitable conditions and a compatible grouping of corals. It is essential to select appropriate species based on the corals desired within the aquarium to prevent any disturbances.

Aquarium Setup

When setting up an aquarium for Black Butterflyfish, it is crucial to ensure the presence of ample hiding places and live rock formations to mimic their natural habitat. Maintaining water quality within the specified parameters, providing a varied diet, and creating enough space for swimming are vital aspects of the setup to promote the well-being of these fish.

Behaviour

Known for their peaceful nature, Black Butterflyfish largely ignore other fish species and can cohabit with multiple members of their own kind, preferably in pairs. They exhibit curious behaviors such as searching through sand for food, which may lead to cloudiness in the tank, and are generally calm and non-aggressive in their interactions.

Feeding and Diet

Black Butterflyfish feed on small crustaceans like krill, mysis, and artemia, along with zooplankton such as cyclops and pods. Although they may initially refuse to eat in a new environment, they typically start feeding within a week and benefit from a varied diet to thrive in captivity.

Dimorphism

Distinguishing between male and female Black Butterflyfish in terms of appearance is essential when maintaining them in pairs for breeding purposes. While captive reproduction is possible with some species, ensuring a suitable environment and diet conducive to reproduction is crucial for successful breeding.

Habitat and Distribution

In the wild, Black Butterflyfish are found in the Pacific Ocean, ranging from Australia to Pitcairn. Their natural habitat includes coral reefs where they feed on soft corals, zoanthids, anemones, tubeworms, and bristleworms. When replicating their habitat in an aquarium setting, it is essential to provide a diverse diet, appropriate hiding spots, and conducive water conditions to support their well-being and longevity.
