Common name: Sixspine butterflyfish

General information

The Ocellate Butterflyfish, also known as the Peacock Butterflyfish, is a striking species that is admired for its beauty and grace in the home aquarium. Its body is predominantly white with a series of black vertical stripes and a distinctive eyespot or 'ocellus' on the dorsal fin, which can confuse predators and provides the fish its common name.

This species is not as commonly kept as some other butterflyfish due to its specialized dietary requirements and sensitivity to water quality. However, for advanced hobbyists, it can be a rewarding challenge.

Care

The Ocellate Butterflyfish requires a well-established aquarium with plenty of live rock for grazing and hiding. They are known to be picky eaters, often requiring a diet of live foods such as clams and shrimp to maintain their health. It is crucial to ensure a varied diet to prevent nutritional deficiencies.

They are generally peaceful but can be territorial towards other butterflyfish. It's important to introduce them to the aquarium at the same time if keeping multiple butterflyfish to reduce aggression.

Reproduction

In the wild, Ocellate Butterflyfish are pelagic spawners, releasing their eggs into the water column where they are fertilized and dispersed by currents. In the home aquarium, breeding is rare and challenging, but not impossible for dedicated hobbyists.

Habitat

Parachaetodon ocellatus is found in the Indo-Pacific region, from the Red Sea and East Africa to the Hawaiian, Marquesan, and Ducie islands, north to southern Japan, south to Lord Howe and Rapa islands. They are typically found in coral-rich areas of lagoon and seaward reefs, from the shallows down to depths of around 30 meters.

Their natural habitat includes a variety of reef structures, which should be replicated in the home aquarium to provide a sense of security and natural foraging opportunities.
