Description
Centropyge eibli is a small marine angelfish, reaching a maximum total length of approximately 7–8 cm (2.8–3.1 in). The species exhibits a typical Centropyge body shape—laterally compressed with a rounded profile. Coloration consists of a predominantly bright yellow to orange base with numerous small, irregular blue or black speckles covering the dorsal region and upper flank. The ventral surface is lighter, often whitish. Fin morphology follows the genus pattern, with a dorsal fin of 13–14 spines and 16–18 soft rays, an anal fin of 3 spines and 16–17 soft rays, and a short, truncate caudal fin.
Distribution and Habitat
Centropyge eibli is native to the western Pacific Ocean. Confirmed records include the Philippines, Indonesia (particularly the western islands such as Sulawesi and the Moluccas), and the surrounding archipelagos. The species inhabits coral reef environments, favoring steep reef slopes, outer reef walls, and sometimes lagoonal reef flats at depths ranging from 5 to 30 m (approximately 16–98 ft). It is typically associated with areas of abundant branching corals and sponge growth, where it can find both shelter and feeding opportunities.
Ecology and Behavior
- Diet: Primarily herbivorous, grazing on benthic algae, epilithic microalgae, and occasionally detritus. Like other dwarf angelfishes, it may also ingest small sessile invertebrates such as sponges and tunicates.
- Social Structure: Usually observed in small harems consisting of one dominant male and several females, though solitary individuals are also common. The species is protogynous hermaphroditic, with the dominant female capable of changing sex to male if the resident male is lost.
- Reproduction: Ovoviviparous, spawning in pairs or small groups. Eggs are demersal and adhere to the substrate; larvae are planktonic before settling onto reef habitats.
Conservation Status
The International Union for Conservation of Nature (IUCN) has not evaluated Centropyge eibli individually; therefore, an official threat category is unavailable. However, its habitat—coral reefs—faces global pressures including climate‑induced bleaching, ocean acidification, and localized impacts such as overfishing and habitat degradation. No specific trade data indicate that C. eibli is a major target of the marine ornamental aquarium industry, though occasional collection does occur.
Human Use
Occasionally kept in marine aquaria due to its small size and attractive coloration. Captive care requires a mature reef tank with stable water parameters, abundant live rock for grazing, and limited exposure to aggressive tank mates.
