Care

Chelmon muelleri requires a well-established aquarium with plenty of live rock for grazing and hiding. They are not considered reef-safe as they may nip at corals and invertebrates. A varied diet of meaty foods, including mysis shrimp and marine flakes, is essential for their health. They can be shy and may require a peaceful tank environment to thrive.

Reproduction

Little is known about the breeding habits of Mueller's Butterflyfish in the home aquarium. In the wild, they are likely to form pairs during the breeding season and release eggs into the water column, which then become part of the plankton.

Habitat

Mueller's Butterflyfish is found in the Western Pacific, from the Great Barrier Reef to the coasts of Indonesia and the Philippines. They prefer shallow, coral-rich areas and are often seen in pairs or small groups.
