生態學
海洋 礁區魚類; 非遷移的; 深度上下限 0 - 30 m (Ref. 7247). 熱帶; 6°S - 30°S, 50°W - 31°W
Western Atlantic: Brazil. Caribbean (described from Cuban specimens) species refers to Stegastes xanthurus (formerly considered as a junior synonym of S. variabilis). Populations from Brazil and the Caribbean are genetically very distinct (Roberstson & van Tassell, 2012; accessed 08 August 2016; http://biogeodb.stri.si.edu/caribbean/en/thefishes/species/3884).
西大西洋: 佛羅里達 (美國) ，墨西哥灣與加勒比海到巴西。

Adults inhabit inshore and offshore coral reefs. They feed mainly on benthic algae but also on sponges, ascidians and anemones while juveniles feed on invertebrates like harpacticoid copepods and nemerteans (Ref. 9626). Often solitary (Ref. 9626). Juveniles are aggressively territorial (Ref. 9626). Aggressive when breeding (Ref. 9710). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Taken incidentally in traps and small-meshed beach nets (Ref. 5217).
棲息於岸邊與外海的珊瑚礁。 成魚主要捕食水底的藻類也捕食海綿，海鞘類與卷曲異輻海葵而稚魚吃像哲水蚤與紐蟲的無脊椎動物.(參考文獻 9626) 時常獨居性的.(參考文獻 9626) 稚魚侵略性具有領域性。 (參考文獻 9626) 侵略性當繁殖的時候.(參考文獻 9710) 在魚籠與小網目的海灘網中附帶地捕獲了。 (參考文獻 5217)
