Michelle,
We have 5 different colors/types of the Gobiodon gobies - Citrinis (Citron), Yellow Clown, Black Clown, Green Clown and a Red/Black Clown that has yet been unidentified. We also have a large amount of peppermints and I've never seen any of the gobies even the slightest bit interested in the peps. For all of them but the larger Citrinis goby, I'd be more worried about a hungry pack of peppermints grabbing them. lol :? . HTH
