what exactly do you what me to say?
since these fish so big, and so aggressive they need a 6footer to reside in.
i do agree that putting them all together in the largest tank, meaning the 135 (if it is indeed a 6'). in doing this you will allow a pecking order to establish, wile this is happening the male and the females will fight. once this order is worked out, then i believe the male will sort him out his pick of the females. thus creating a "semi-natural" selection of a pair of RDs.
you will however have to then separate the remaining females once again.
hopefully this will help. sometimes with larger fish that have been put in solo tanks wile growing up. these fish can be hard to re-socialize. these problems you seem to be having is just this thought. most if not all your RDs have been kept solo, for means of aggression. so when these get put together with other fish the dominance issue and pecking orders come into play. without having enough fish to spread aggro, this cause one fish to generally beat on the weaker one. i'm sure you know this already.
also remember that the male got quite a beating on his first encounter with your large female. haha!
have you had any luck breeding any other large species of cichlids?
i wouldn't sell them
YET......
