Trying to pair up these dwarf cichlids ( blue rams) is not as easy as putting two fish together.
However you say it they pick their mate. They can fight and stress out ( kill) a fish that’s not doing what is required. Even a happy pair that has been laying eggs can go bad if one decides the other did something wrong ( ate the eggs ) .
Unless you have a spare tank just leave things as they are .” As is”
Long before eggs are even though of these fish are troublesome with partners.
The Bolivian is a better behaved fish IMO
