No. The fish we have seen in your pictures are def. Albino Socolofi...
its possible, but my fish's fins have a red ish tint to it. an some of the fish in the tank looked just like mine...
Body shape, and even head shape will tell all (colors are irrelevant when determining if zebra or socolofi).
...could they breed if i put them in the same tank? and would they kill each other?
That's a possibility with any mbuna or other type of african cichlid type. The likihood of either happening will depend on variables and factors. I personally have had no problems keeping socolofi's with zebras (in regards to extreme aggression or interbreeding, but this is in a larger tank).
I personally wouldn't keep any zebras or socolofi in a tank smaller than a 55gal, unless they're juvies (2.5" or smaller). Larger than that and in a tank smaller than a 55gal introduces aggression potential which most likely wouldn't occur in a larger tank.
Interbreeding will depend on gender ratios. Despite the albinism, albino zebras and 'snow white' socolofi will be able to immedially identify their own type as will the pigmented morphs of each species (i.e., if you kept snow white socolofi's, albino zebras and powder blue socolofi's, the male blue socolofi's would challenge the male snow white socolofi's, color isn't a variable to them). Zebra-socolofi interaction would be minimal, despite the perceived similarity in appearance (with the exception of general mbuna dominance 'power plays' which can involve any mbuna in the tank, regardless of species).
If your gender ratio's are out of whack, interbreeding possibility increases (example, 2 male snow white socolofi, 4 female snow white socolofi, 2 male albino zebras will force the zebras to attempt to interbreed with the female socolofi's).
