What Eyestripe Surgeonfish look like
The Eyestripe Surgeonfish, Acanthurus dussumieri, exhibits a streamlined, oval body shape that can reach a maximum adult size of approximately 12 inches (30 cm). This species is characterized by its distinctive coloration, featuring a bluish-gray body adorned with a prominent yellow stripe that runs horizontally from the eye to the base of the caudal fin. The fins are typically yellow, with the dorsal fin being long and pointed, while the anal fin is shorter and rounded. Sexual dimorphism is subtle, with males often displaying slightly more vibrant coloration during breeding periods. A notable defensive adaptation is the presence of sharp, retractable spines located on either side of the tail, which can inflict painful wounds when threatened. Additionally, the lateral line is well-defined, aiding in the detection of water movements and potential predators.
Behavior & temperament
Acanthurus dussumieri is generally a social species, often found in small to medium-sized schools, particularly in shallow reef environments. They exhibit a hierarchical social structure, with dominant individuals displaying more vibrant coloration and engaging in aggressive posturing to establish territory. The Eyestripe Surgeonfish is primarily a mid-water swimmer, frequently foraging among the reef's crevices and algae-covered surfaces. Breeding behavior involves the formation of spawning aggregations, where males and females engage in synchronized swimming and release gametes into the water column. Their temperament can vary, with individuals displaying territorial aggression, particularly during breeding seasons.
Diet & feeding
In the wild, the Eyestripe Surgeonfish primarily feeds on algae, particularly filamentous algae, making it an important herbivore in reef ecosystems. In captivity, they require a diet rich in marine algae, spirulina, and high-quality herbivore pellets to maintain optimal health.
Behind the name
The genus name 'Acanthurus' is derived from the Greek words 'akantha' meaning 'thorn' and 'oura' meaning 'tail', referring to the sharp spines on the tail. The species name 'dussumieri' honors the French naturalist, Jean Dussumier.
