I could follow these Zebra Fish (Girella zebra) around all day as they cross from here to there.
Photographing them is easy. Just watch for a while as they traverse their circuitous route through pylons, reef and and bottom debris and they will eventually come round again. All you need to do is wait.
I chose this spot to wait near the old Rapid Bay Jetty and on their own schedule they crossed my path as planned.
