Ummm...those are defienatly not Maylandia Livingstonii. They are peacocks, and Im guessing the one showing color is a line bred/hybrid Red Rubescens peacock
I should have mentioned they are all from the same parents so all are the same. They very well could be hybrids. I picked them up from my lfs to try to bring my red devil out of her shell. Unfortunately it didn't work, she passed away after having her for 9 years.
