Seargeant Majors; genus Abudefduf

Seargeant Majors are actually named after their bossy behaviour towards other fish, including those bigger than themselves. Our Koh Phangan species seem to be planktivores, living off small creatures in the water column.

A small reef dweller, seen mainly at Mae Haad and Chaloklum Reefs on Koh Phangan.

Not so common, solitary, darker body and distinctive yellow tail.

Their tails are marked like scissors. These Seargeants can be found in large (feeding) schools in the shallows.

Identified by the black spot in front of the tail, maybe...

The yellow shading to the top of the body sets this Seargeant apart from the others.
