Jewel cichlids with these types of fish?

well i am breeding german blue rams and i have a breeding pair. i have a 55gal 210 litres and there is a tank divider in the middle of the tank because i have some other rams and a peppermint bristle nose and i don't want them to eat the ram fry and eggs. so the pbn is only about two inches this is a pic of him. file:///C:/Users/isam/Pictures/DSC_0064.… And i really want to know if he will be fine and the other rams if i put 2 or one jewel cichlid in the tank
