I was also thinking about transferring my (female) blue gourami from my 30 to my 75 because she is getting a bit cramped being in a tall tank and could use the swimming space. So would -1 striped raph and +1 blue gourami sefice? I would get more Gouramis to keep it company but I don't want to be pushing my bioload. If you think it would be better with other Gouramis I could also swap out the acara for a few more (can any different kinds of Gouramis (not golds) get along and maybe even shoal with blues such as pearls, moonlights, kissings?
