Personally, I believe a 30 gal is too small for two males. A male and two females would be fine, but it's not enough room for the two males to establish territories. Unfortunately females are really hard to come by.
Honey gourami are a much better bet for reasons already mentioned. They can also be kept in groups if it is a male and multiple females. This tank would be large enough for a group of honeys.
Dwarf gourami are really pretty fish. I wanted one for my 30 gal tank, but I opted for thick lip gourami instead due to the multiple health issues with the dwarf gourami. Thick lip gourami are about the same size as a dwarf gourami but don't come with all the health problems. They are a bit more sensitive, tho.
