Plotosus lineatus

The young live in shoals where they form a ball, with their heads facing outwards, when they are faced with danger; the adults are more solitary. They feed on animal foodstuffs or small prey appropriate to the size of their mouth. This fish has a reputation for being fragile and an avid consumer of oxygen. Size: 30 cm.
