Different sighting. This one was on a gum tree. Clouded Footman?
Tight school of small adults WNW of jetty. Poor quality photo but FWIW I also note the small Silver Drummer below the school.
Juvenile.
Anecdotally these seem to be becoming more common than ever in my diving lifetime here in SA and global warming makes a handy explanation if this becomes fact rather than just anecdotal:)
Such beautiful fish!
