I've found I had success in some other tanks using tetras as dither fish. I got my upside down cats to come out and swim around by having a bunch of black neons and glow lights around. I don't really want anything too hyperactive (like danios), but just something that'll swim around in the mid to upper portions of the tank and hopefully make the gourami's feel more secure.
