Biology : The yellow surgeon lives in a school. Individuals may occasionally squabble to establish or maintain hierarchy in the group.
Like all surgeon fish, it has a spine at the base of its tail. This is similar to the scalpel used by surgeons, hence the name. This spine is an effective means of defence.
