fish identification

Hi, I've just returned from a holiday on the Algarve. While feeding the
mullet in a nearby harbour I spotted an unusual fish. Can anyone help
me identify it please?

It was shaped like a perch (round and plump in depth but quite slim in
width), silvery in colour but with distinctive large bright blue eyes
or eyebrows (dont laugh!) It had quite big lips and only one set of
triangular fins just in front of its tail, above and below, these were
also bright blue and both sets where the same size. When it swam its
fins waved alternatively. The mullet seemed afraid of it although it
wasnt much bigger than about 12" in length. It ate the bread but I also
saw it feeding off the barnacles on the harbour walls.

Would be very keen to find out what it is because I've searched fishy
pics and havent seen anything quite like it! An old chap who had a boat
in the harbour and was a keen fisherman hadnt a clue what it was either!



Fin structure, alternate waving of fins, blue eyes, feeding off
barnacles....
A juvenile gray triggerfish?
