Mediterranean rainbow wrasse

The Mediterranean rainbow wrasse (Coris julis) is a small, colourful fish in the family Labridae. It can be found in the Mediterranean Sea and in the northeast Atlantic Ocean from Sweden to Senegal (though it is a rare wanderer to the southern British Isles).[2][3] Records of this species south from Senegal and the Cape Verde Islands are actually the closely related Coris atlantica.[3]

It feeds on amphipods, isopods, sea urchins, polychaete, shrimps, and small gastropods.[3]
