Habitat
This species primarily inhabits coral reefs and lagoons in tropical marine environments, often at depths of 3 to 30 meters. It prefers areas with abundant live coral and clear water, commonly found in the Indo-Pacific region including the Red Sea and Hawaiian Islands. Geographic preferences include sheltered reefs and outer slopes with strong currents.
Diet
The lined butterflyfish feeds mainly on coral polyps, small benthic invertebrates like worms and crustaceans, and occasionally algae. It grazes during the day, using its elongated snout to pick at coral surfaces, and is known for its selective feeding behavior to avoid toxic corals. Feeding typically occurs in pairs or small groups around coral heads.
Behavior
Lined butterflyfish are diurnal and often seen swimming in pairs or small groups, though they can be solitary at times. They exhibit territorial behavior, aggressively defending their feeding areas on coral reefs from intruders. Notable behaviors include rapid darting movements to evade predators and a tendency to form loose aggregations during spawning periods.
Conservation Status
Listed as Least Concern by IUCN.
