I just bought 2 of Ojo chico 8 inches or so get them tuesday. So if I find something that is different between them I will post it? I don't know either?
They're both Panaque bathyphilus just different common names. 'Ojo Chico' will be a location within the Ucayali drainage where this sort is found. They tend have an orange colour to to their caudal tail and filaments and their body colour varies is usually dark brown with flecks of grey.
