This fish I photographed at Cosmocaixa Science Museum (check mark on map). There is a big tank with exotic species in a simulation of a jungle habitat in the Amazonian rivers. I can't tell you what it is. It looks like a snook to me because of the shape but it doesn't have a lateral stripe. There were also pirannas in there. There is a part of the tank where you have the water level at the reach of your hands, there is no protection, just a sign that says "watch it, pirannas are carnivore fish" although someone told me there is a herbivore specimen. I suggest you don't try to find out.
