Which is from South America, or different places around the world.
please, and thank you.
semaprochilodus taeniurus, insignis, theraponura, squamilentus, laticeps & kneri are the main ones...there are a few others
id say the true flagtail is the insignis, just because its named flagtail prochilodus, while the taeniurus is named silver prochilodus
coolest 1 is the theraponura. males are hi-fin & they max at 40cm
