False-Eye Sergeant

Abudefduf sparoides

The False-eye Sergeant is a tropical damselfish found in the western Indian Ocean, from Kenya to KwaZulu-Natal, South Africa, and around islands such as Aldabra, Madagascar, Mauritius, and Réunion. Typically, this species inhabits coral and rocky reefs exposed to moderate wave action, at depths ranging from 0 to 6 meters. Juveniles are often seen in lagoons and shallow, flat environments. The False-eye Sergeant features a distinctive black blotch on the middle of its caudal peduncle, which is larger than its eye, aiding in identification. This species primarily feeds on algae, but its diet also includes crustaceans and small invertebrates. It is an oviparous fish, meaning it lays eggs, and forms distinct pairs during breeding. Males play an active role in guarding and aerating the eggs, which are demersal and adhere to the substrate. Divers may encounter these fish either alone or in loose aggregations, making them a solitary but occasionally social species. The False-eye Sergeant is classified as 'Least Concern' by the IUCN. While not of interest to fisheries, it contributes to the ecological balance of reef environments. Divers might find this species in shallow reef areas, where its unique markings and behavior can be observed.
