Photographed yesterday at L\'Aquarium de Barcelona, Spain. The labeling in this aquarium is the worst that I even seen in any aquarium, lots of fishes in the tanks that lack completely any informative label and lots of informatibe labels for fishes that are not present in these aquariums. And even worst! This fish, in a seahorse tank, was labeled as Clinitrachus argentatus, and clearly it is not. Not even in Clinidae family. But what is it?
