you'll just have to try it. my guess is that maybe two golds (one male only) and a dwarf would be better. one gold would probably pick on the dwarf. if it were a small gold and a large dwarf you might be able to pul it off.
it really all depends on the fish. i had a dwarf flame that picked on my blue, and then again i've also had it vice versa. but generally, i'd say yes, they will get along. just do lots of plants and hidhing spaces and you should be OK.
