In reference to my image above:
The fish pictured was one of a pair. The two stuck close together while feeding on what appeared to be bryazoans encrusting the pylons of the wharf. They also picked at the surface of Ecklonia kelp, which again, appeared to be feeding behaviour.
If the pair was seperated during their movements by more than a metre or so, one of them would quickly dash back to find its partner.
Judging by their size, they were juveniles.
