I have a Gold Severum and i just wanted to give you a word of warning, altho its mentioned in their profile they are "Peaceful Giants" they can be quite aggressive too in my experience.
Mine lives with Green Terror, Jack Dempsey, Blue Acara, Salvini & Firemouth Cichlids. All in all a pretty aggressive set up, now he dont mess with the Green Terror or the Jacks but he will chase off the Blue Acara, Salvini & Firemouths when they get in his way, these fish are much more robust and larger than the Dwarf Gouramis you intend to house with a Gold Sev. Im not saying dont house them together they may be perfectly fine, but just keep an eye on them when introduced to each other.
