I know where you live
That si not good.
Pairs will scuffle from time to time, it's not unusual to see torn fins on breeding pairs. Things like this are the reason anyone dealing with cichlids should have a divider. Pairs can get aggressive for no apparent reason, and have been known to kill their mate.
An actively breeding pair should get a diet heavier in protein, I hope you are feeding something other than flake food & the weekly feeding of bloodworms.
