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).
主要发现于岩石与沙子形成一个中间的生存环境的地方了。 雌性那是独居性的相似雄性能进入被发现于岩石中, 而且产卵的雄鱼的领土.(参考文献 5595) 吃鱼苗。 (参考文献 267) 当进食, 它转在它的侧边把它的大又侧扁颚放进入岩石的裂缝之内，在哪里它抓取小鱼那是哪里隐匿.(参考文献 6307)
