The kennyi tends to be one of the first in the tank to hybridize with other species, in fact, my dominant male has bred with my female red zebra cichlid about 4 times! I saved one brood, and they are about an inch long. some are orange, and when the sun hits them, they shine blue stipes. the others look like baby kennyi, but are dark navy blue, without iridescents.
if you have female kennyi with the males, they breed just like other Malawi cichlids/mbuna, but very easily. the male will "dance" in front of the female by flaring his fins and shivering his body/fins. if she is impressed, she will clamp her fins in submission and follow him to his 'spot', be it a rock or cave. when she lays the eggs, she picks them up in her mouth for incubation. if she is removed to her own tank, she will eventually spit out fully formed fry after approximately 21 days without eating and guide them around the tank for a time after. she will even scoop them up into her mouth at the first sign of danger. if in a community tank though, she will hold them even after her normal time, then release them to their own devises, usually being eaten by the other tankmates unless given sufficient hiding and their fare share of food.
Kennyi are very aggressive, yet easy to care for an breed. good luck!!!
