Found mainly in places where rock and sand form an intermediate biotope. Females which are solitary like males can enter the male's territory found among rocks, and spawn (Ref. 5595). Feed on fish fry (Ref. 267). When feeding, it turns on its side to place its large, laterally compressed jaws into rocky cracks where it captures small fish that are sheltering there (Ref. 6307).
主要發現於岩石與沙子形成一個中間的生存環境的地方了。 雌性那是獨居性的相似雄性能進入被發現於岩石中, 而且產卵的雄魚的領土.(參考文獻 5595) 吃魚苗。 (參考文獻 267) 當進食, 它轉在它的側邊把它的大又側扁顎放進入岩石的裂縫之內，在那裡它抓取小魚那是那裡隱匿.(參考文獻 6307)
