Ankhios was one of the Kentauroi who went into a frenzy at the mere smell of the wine fellow Kentauroi Pholos was serving to Herakles when Herakles was on his journey to find the Ermanthian Boar. Ankhios and the other Peloponnesioi Kentauroi (with the exception of Pholos) attacked Herakles and in the insuing fight were all but wiped out by him. It is most likely that Ankhios was among their number.
