Just had a thought... isn't it rather unusual to find a fish like this
in a harbour in Portugal? According to the Florida Museum of Natural
History website
they are mostly found around America and only occasionally around the
med.

First of all it doesn't have be exactly the Gray Triggerfish. There are
numerous species of Triggerfish. But your description
came quite close to describing one, especially the top and bottom fins
waving alternately.
While triggerfish conjures up images of tropical fish as there are many
colorful ones in warm waters, in the U.S.
they can be found as far north as New York in the summer months.
I'm not sure why you would consider this fish unusual or in Portugal. In
Greece it is called gouroupsaro and Mih in Croatia.

If you check the distribution maps in FishBase (click the AquaMaps link
to generate it) you will see that the Gray Triggerfish has an enormous
distribution on either side of the Atlantic. To see the actual data
points behind the generated map click the "Point Map".

On the eastern side it is known up to the British Isles and almost down
to South Africa and on the western side from New Foundland to southern
Brazil.
