That's not quite true at all. KML is actually their own strain and not a ZZ x Kamfa. Anything ZZ x Kamfa would either be classified as ZZkamfa or KamfaZZ depends which trait is more dominant. KML itself is actually the latest version of the GM strain. Although the KML strain is arguable that there may be a good amount of ZZ strain been diluted into them. You can try and do a ZZ x Kamfa breeding session up to F6 - anything over F6 will be a ton of deformity. I will guarantee that it will not breed true like how KML is suppose to be.
These fish may not be KK or Kamfa just to stay put on there. But I can see them being Kamfamalau...assuming the mom is the KML. Nice fish either way - keep us posted!
