Care

Caring for Frembli's Butterflyfish can be challenging due to their specialized dietary requirements. They primarily feed on coral polyps and benthic invertebrates in the wild, so providing a varied diet that includes live foods and marine-based preparations with sponge material is crucial for their well-being in captivity.

Reproduction

Little is known about the reproductive habits of Frembli's Butterflyfish in the wild or in captivity. However, like many butterflyfish, they are likely to form monogamous pairs and engage in elaborate courtship displays.

Habitat

Chaetodon fremblii is endemic to the Hawaiian Islands, where it inhabits coral reefs and lagoons. It is typically found at depths ranging from shallow waters to about 30 meters. The species prefers areas with abundant coral growth, which provides both food and shelter.
