Care

Townsend's Anthias are considered moderately difficult to care for, primarily due to their specific dietary requirements. They thrive on a varied diet that includes small zooplankton, mysis shrimp, and other meaty foods. Frequent feedings are necessary, as they have a high metabolism and are accustomed to constant grazing in the wild. A well-established aquarium with plenty of swimming space and hiding spots among live rock is essential for their well-being.

Reproduction

Like many anthias species, Townsend's Anthias are protogynous hermaphrodites, meaning they are born female and have the ability to change to male if the dominant male is removed from the group. In the aquarium, breeding can be challenging, but with a stable environment and proper group dynamics, it is possible to observe their fascinating reproductive behavior.

Habitat

Townsend's Anthias are typically found in the Western Pacific, where they inhabit coral-rich areas and steep outer reef slopes. They prefer depths ranging from 25 to 60 meters, where they form aggregations above the reef, often in the water column or near the edges of drop-offs.
