General information

The Threadfin Anthias, scientifically known as Nemanthias carberryi, is a vibrant and active fish that adds a splash of color to any saltwater aquarium. This species is part of the Anthiinae subfamily, which is known for its brightly colored members. The males exhibit a striking red-orange hue with elongated filamentous rays on the dorsal fin, while females and juveniles are more subdued in coloration, typically displaying a yellow-orange body with a purple hue on the dorsal fin.

Care

Threadfin Anthias are moderately challenging to keep due to their specific dietary and social requirements. They thrive in well-established aquariums with plenty of swimming space and numerous hiding places among live rock. A peaceful community tank is ideal, as they can be shy and may be outcompeted for food by more aggressive fish. They require a diet of small, meaty foods multiple times a day to maintain their health and coloration.

Reproduction

In the wild, Threadfin Anthias form harems consisting of one dominant male and several females. If the dominant male perishes, the largest female will undergo a sex change and take on the male's role. In the aquarium, breeding these fish can be challenging, and it is often not attempted by hobbyists due to the complexity of rearing the larvae.

Habitat

Nemanthias carberryi is found in the Indo-Pacific region, particularly around the Maldives, Sri Lanka, and the Andaman Sea. They typically inhabit outer reef slopes and drop-offs, where they can be seen swimming in large aggregations just above the reef, feeding on zooplankton.
