What size a tank are they going to be in? I bred them for a while and had them with everything. As long as I removed fry when they became free swimming nothing really bothered then much. I had two pairs breeding alternately in a 75 gallon with discus, green neon and ruby tetras, Dicrossus, bristlenose, Sturisomatichthys, L46, L519. The Dicrossus would start hunting down fry. If you're running just the rams in a smaller tank than 75 go with small tetras. Cichlids are relentless and barbs won't do well in the >80° temperatures.
