生物學特性     字彙 (例如 epibenthic)

Adults inhabit shallow, coral or rocky bottoms and sometimes near the shore in areas with little visibility (Ref. 9626). Juveniles were collected from tide pools and on rocky Lithothamnion reefs; adults found up to 15 m depth (Ref. 40395). A diurnal species, adults feed on benthic algae, polychaetes and harpacticoid copepods (Ref. 9626); also consume hydroids and sponges and has been observed to feed on Abudefduf saxatilis eggs at night (Ref. 9626). 16:21 SL/TL (Ref. 9626). Oviparous, distinct pairing during breeding; eggs are demersal and adhere to the substrate; males guard and aerate the eggs (Ref. 205).

以確定記錄只從巴西的海岸。 棲息於淺灘, 珊瑚或者岩石底部而且有時在海岸的附近在有小能見度的區域中.(參考文獻 9626) 一個日行性種, 它吃水底的藻類,多毛類動物與哲水蚤.(參考文獻 9626) 成魚也消費水息蟲與海綿而且已經被觀察覓食 岩豆娘魚〔Abudefduf saxatilis〕 卵在晚上.(參考文獻 9626) 16:21 SL/TL.(參考文獻 9626)
