Welcome to the forum! Have you been keeping fish long? Cichlids? Just wanted to suggest you do some research on Kenyi before you buy as they have a reputation as trouble-makers.
I also use New Life Spectrum Cichlid Formula. And I agree with Gibbs on the Lab/Zebra hybrids too. As you can see from my signature, I keep them together, but have 11 Synodontis in the tank to take care of any fry from them.
I feed NLS cichlid formula also. I just started feeding NLS about a month ago and my fish love it. Their color looks better too. I alternate spirulana flakes with occasional brine shrimp (once a week).
