I'm still on the lookout for the right "goldfish-like" fish to be the focal point of my 55g tank. (My daughter wants a goldfish, but I know you can't keep an actual goldfish with tropical fish.) The tank has sand substrate and will be inhabited by cory cats, a larger cat, an eel, and maybe some schooling fish.
Originally I was looking at a red parrot cichlid or some longfin rosy barbs for my large pseudo-goldfish. But I think a gold gourami (or more than one) could work. So: would gold gouramis behave in such an environment? And would I want just one, or a pair (what sexes?), or more than a pair? I gather they can be aggressive if the circumstances aren't right, and they can be peaceful if everything is as it should be.
