Range and Identity
Pterocaesio trilineata is the retained scientific name for this Indo-Pacific fusilier. The checked summary provides a broad region rather than a detailed locality map. That outline should not be expanded into confirmed occurrence at every reef or island within the two oceans.
Habitat and Behavior
The fish ranges around coral reefs and feeds in midwater aggregations. This is a water-column feeding position associated with reef surroundings. It differs from scraping algae or collecting prey directly from the bottom, neither of which is established by the account.
Food and Life History
The upper reference is twenty centimeters total length. The common thirteen-centimeter measurement uses standard length, so the two figures require their labels. The species lays numerous small pelagic eggs rather than attaching a guarded clutch to reef rock.
Field Note
Note school position above the reef and preserve a clear individual photograph. A distant group image may show habitat and schooling well while leaving species-level markings difficult to assess.
