i hope you have male/female pairs, because otherwise you have a massive aggression problem on its way. most notably, the blues and golds are in fact just color varients of the same species, so unless two of them are females, you're probably going to have some nasty fights as they get older. actually, you'll probably have issues even with two females as the males compete whenever a female goes into breeding condition.
i wouldn't add the rams. you've got quite a bit going on in that tank already without a small set of breeding cichlids.
best of luck!
