Inhabits coral reefs (Ref. 58534). A nocturnal species (Ref. 75154).

Occurs along exposed reef margins and outer reef slopes. Has been observed at depth of 183 m in Hawaii (Ref. 1602). Benthopelagic (Ref. 58302). Secretive during the day and hides in holes and crevices of surge channels. Feeds at night on crustaceans, crustacean larvae, polychaete worms, and small fishes. Spine of preopercle venomous.

分布於印度-太平洋區，西起東非到夏威夷、馬貴斯群島與迪西島，北至日本南部，南至澳洲與奧斯垂群島。臺灣分布於西部、南部及蘭嶼等海域。

一般以一支釣及延繩釣的方法捕獲。魚肉白，但質地較爛，煮湯時肉易散開且多溶解油質，因此適合抹鹽油煎食用。唯須注意其內臟可能累積熱帶海魚毒。而它的鱗片及棘刺尖利，需小心刺傷。在水族館中也有人看上它鮮紅的體色，將它飼養做為觀賞魚。

體呈橢圓形，中等側扁。頭部具黏液囊，外露骨骼多有脊紋。眼大。口端位，裂斜。下頜不突出於上頜。前上頜骨的凹槽大約達眼窩的前緣垂直線上；鼻骨的前緣有兩個分開的小棘；鼻窩沒有小刺。前鰓蓋骨後下角具ㄧ強棘，長度約等於眼徑；眶下骨上緣幼時具小棘，長大後平滑。體被大型櫛鱗；側線完全，側線鱗數 47-52，側線至背鰭硬棘中間點之鱗片數 2.5；頰上具 5 列斜鱗。鰓耙數6-8+13-15=19-23。背鰭連續，單一，硬棘部及軟條部間具深凹，具硬棘 X-I，軟條 14；最後一根硬棘短於前一根硬棘。臀鰭有硬棘 IV，軟條 9；胸鰭軟條 14-15(14)；尾鰭深叉形。體為紅色，體側具銀紅色斑紋，並有藍色的虹彩；背鰭硬棘部紅色，棘的尖端白色，而在每個鰭膜的中央有一個白色的斑塊；餘鰭皆為紅色，腹鰭與臀鰭硬棘的前緣為白色。

主要棲息於礁岩邊緣或礁岩斜坡外圍，深度範圍一般在１到２０公尺左右。在夏威夷有深達１８３公尺的記錄存在。白天非常神祕，愛躲在洞穴中或碎浪帶水道的縫隙中；晚上則出來活動覓食，以甲殼動物、甲殼幼生、多毛類和小魚等為食。
