Common name: Swallowtail seaperch

General information

The Swallowtail Seaperch, scientifically known as Anthias anthias, is a vibrant and active fish that adds a splash of color to any marine aquarium. They are part of the Serranidae family, which includes groupers and sea basses. These fish are known for their bright pink and orange hues, with males typically exhibiting more intense coloration and a distinctive lyre-shaped tail.

In the wild, Swallowtail Seaperch form large aggregations, often seen swimming in the water column above the reef. They are a popular choice among advanced aquarists due to their striking appearance and interesting behavior.

Care

Anthias anthias require a well-established aquarium with plenty of swimming space and a tightly fitting lid, as they are known to be jumpers. They thrive in a water environment with strong currents and high oxygen levels. 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 sensitive to water quality changes, so regular water testing and maintenance are crucial. They are best kept in groups, with a single male to several females, to mimic their natural social structure and reduce aggression.

Reproduction

Swallowtail Seaperch are protogynous hermaphrodites, meaning they are born female and have the ability to change to male later in life. This usually occurs when there is an absence of a dominant male in the group. In the aquarium, breeding is challenging but possible with stable conditions and a well-structured social group.

Habitat

The natural habitat of Anthias anthias spans the Eastern Atlantic, from the Bay of Biscay to South Africa, including the Mediterranean and Black Seas. They are typically found in offshore rocky reefs and slopes, at depths ranging from 10 to 200 meters.

Their preference for deeper waters with strong currents should be considered when replicating their environment in the home aquarium.
