Description
Variable colouration from plain red-brown to silvery, with the ability to rapidly fade or darken in to diffuse blotchy bars on body, though always with a red patch below eye. Rear fins lacking spots, tailfin margin slightly rounded or straight. Indistinct black spot at base of pelvic fin (not visible in photo), like in P. hamrur(Lunartail Bigeye), but has flatter tail margin. Similar P. macracanthus has numerous red spots on pelvic fin instead of single black spot near base.
