The black and tan one is named Ulysses, and the white and tan one is named Cliff!
They both enjoy carrots, cilantro, lettuce, and broccoli- dislike brussel sprouts. Blech! Fun fact: Cliff and Ulysses love their daily Vitamin C tabs. Primates (like human beings) and guinea pigs are the only mammals that do not produce Vitamin C and will get scurvy if it is not provided in their diet.
