Care

Caring for the Milletseed Butterflyfish can be challenging due to its dietary requirements. In the wild, they feed primarily on coral polyps and small invertebrates. In captivity, they require a varied diet that includes marine algae, mysis shrimp, and other meaty foods, as well as preparations designed for marine herbivores and omnivores. A well-established aquarium with plenty of live rock for grazing and hiding is essential for their well-being.

Reproduction

In their natural habitat, Milletseed Butterflyfish form monogamous pairs during the breeding season. They are pelagic spawners, releasing their eggs and sperm into the water column where fertilization occurs. The eggs are then left to drift in the currents. Reproducing them in the home aquarium is quite difficult and rarely achieved.

Habitat

Milletseed Butterflyfish are found in coral-rich areas and clear lagoons within the Hawaiian Islands. They prefer shallow waters but can be found at depths of up to 180 feet. Their natural environment is characterized by abundant live coral, which is crucial for their feeding habits.
