This little guy under Rapid Bay Jetty is a Western Cleaner Clingfish,
Cochleoceps bicolor.
In more than 25 years of diving this location, this year is the first time I have seen them here.
The first time was back in late winter when my dive buddy Alexius found one during one of our dives. Since then I can find at least one on most dives here.
As I have mentions before, the thing I love about clingfish is that they always look like they are smiling at me.
