Which other fish to get to help train my Greissenger Goby to eat prepared foods (after i get him tomorrow)

Ok so i plan on picking up a Greissenger Goby and housing this little guy in a 2.5 gallon tank with live rock (bound to have plenty of copepods on them since they're from my other tanks) but would like to train him to eat prepared foods and I've heard a good way to go about this is by having another less picky fish eat prepared foods...what fish should i get to help train him? A Yasha goby? Clown goby?
