Common name: One-stripe anthias

General information

The Red Sea Anthias, also known as the Swallowtail Anthias, is a vibrant and active fish that adds a splash of color to any reef aquarium. This species is part of the Pseudanthias genus, which is known for its brightly colored members, and Pseudanthias fasciatus is no exception with its pinkish-orange body and purple stripes.

These fish are predominantly found in the Red Sea, hence their common name, and are a popular choice among aquarists due to their striking appearance and dynamic behavior. They are relatively peaceful and can be kept with a variety of other reef-safe fish.

Care

Red Sea Anthias require a well-established aquarium with plenty of swimming space and hiding places among live rock. They thrive in a stable environment with consistent water quality. A varied diet of meaty foods such as mysis shrimp, brine shrimp, and finely chopped seafood is essential for maintaining their health and coloration.

These fish are known to be jumpers, so a secure lid or screen is recommended to prevent escape. They do best in groups, with a single male and multiple females, as they exhibit a hierarchical social structure.

Reproduction

In the wild, Red Sea Anthias are protogynous hermaphrodites, meaning they are born female and can change to male if the dominant male is no longer present. In the aquarium, breeding can be challenging due to their complex social dynamics and the need for precise water conditions.

Habitat

Pseudanthias fasciatus is native to the Red Sea and the Gulf of Aden. They are typically found in coral-rich areas and steep reef slopes, where they swim in large aggregations. These fish prefer depths ranging from the surface down to about 60 meters, where they feed on zooplankton carried by the currents.
