Forms mid-water aggregations off steep slopes during the day to feed on zooplankton. Usually found alone or in pairs. Omnivorous. Has the ability to show or hide its blue markings (Ref. 9710). Minimum depth reported taken from Ref. 27115.
出現於深的潟湖與臨海礁石。 陡坡外的中層水域聚集成群在白天期間覓食浮游動物。 通常單獨或成對發現。 雜食性。 有能力顯示或者隱藏它的藍色斑紋。 (參考文獻 9710) 最小深度報告取自參考文獻 27115.
