First sighting of Zebrasoma flavescens (Teleostei: Acanthuridae) and Balistoides conspicillum (Teleostei: Balistidae) in the Mediterranean Sea: Two likely aquarium releases

Abstract

Here we provide the first documented occurrence of the yellow tang Zebrasoma flavescens and of the clown triggerfish Balistoides conspicillum in the Mediterranean Sea. These tropical fishes were photographed in October 2008 off Sitges (Costa Daurada, Spain: 41°13'27.09" N; 1°47'22.35" E) and in July 2012 in front of Palamós (Costa Brava, Spain: 41°50'56.19" N; 3°8'26.29" E), respectively. Their possible release from private aquaria is discussed.
