Kenyi are extremely aggressive Mbuna and a single specimen when it matures will claim an entire tank up to 100 gallons in size and begin systematically killing all other fish in the tank. They look nice, but IMO they belong in a very large species only tank.
Blue and Red Zebras are different species and you are creating hybrids by allowing them to interbreed. Just because the female reds are electric orange and the male blues are blue, doesn't mean the hybrids will be. You could end up with all OB hybrid offspring or some other result.
