📖 Overview

Adults occur in clear waters and coral-rich areas of lagoon and seaward reefs commonly in seaward reefs . Benthopelagic . Juveniles are solitary, living among branching corals, while adults are almost always in pairs and are home-ranging. They feed exclusively on coral tissue . Oviparous . Form pairs during breeding . Minimum depth reported taken from Ref. 128797.

🔬 Taxonomy

🐟 Physical Description

Dorsal spines (total): 12 - 13; Dorsal soft rays (total): 24 - 28; Anal spines: 3; Anal soft rays: 20 - 23. Body is white with orange to orange-brown oblique bands on the sides. Two broad yellow-edged black bars are on the head; one running across the eye and another on the snout . Snout length 2.6-3.2 in HL. Body depth 1.3-1.6 in SL .: short and / or deep; Cross section: compressed.

🌀 Behaviour

Ornate butterflyfish adults are predominately found in pairs that occupy exclusive territories including Clearwater lagoons and seaward reefs rich in coral growth (size range ~100-1400m2). On the other hand, juvenile Chaetodon ornatissimus live in solitary, tend to be shy, and hide in the arms of branching corals for protection. Once juveniles reach breeding age, they form pairs. It is uncommon to find adult Chaetodon ornatissimus without a mate. Pairs also establish a "home range" where they are likely always to be found.
