Gouramikeeper83, the size of a 30g is a limiting factor to many of the more common gourami species, so bear that in mind. We have profiles of these species, under the second tab from the left in the blue bar across the top of the page. When the name is used the same in posts as in the profile it will shade, example Dwarf Gourami, and you can click it to see that profile. Information on tank sizes, numbers of the fish, and other issues is included in each profile.
In tanks less than 4 feet in length, only one gourami species should be considered. The exception to this is the several very small species (Chocolate, Licorice, Sparkling, etc). Pearl Gourami get largish, so a pair would be it for gourami in a 30g. Males are territorial to other males, and all gourami species males. The dwarf gourami is not a recommended fish unless you know the source, and by this I don't mean the store but the actual breeder. This too is explained in the profile. This may have been the cause for the demise of the other member's fish.
