生物学特性     字汇 (例如 epibenthic)

Juveniles inhabit shallow protected areas, while adults prefer coastal reefs with heavy coral growth providing ample hiding places. Generally solitary or in pairs. Feeds on sponges, tunicates, and algae (Ref. 30573). The young are excellent aquarium fish and suitable for a community tank.

稚鱼栖息于水浅且有遮蔽的区域, 虽然成鱼用提供充足的藏身处的大量珊瑚成长偏爱岸礁。 通常独居性或成对。 吃海绵,被囊类与藻类。 (参考文献 30573) 幼鱼是优良的水族馆鱼并且适合做一个公众的水族馆鱼。
