Ornatum and atromaculatum are also more closely related to CA's than SA cichlids. Though I haven't heard of any cases of them hybridizing with CA's, probably due to the fact that they are uncommon in the hobby.Basically, no SA can breed with a Festae and produce viable fry. 'Cept CAs that have moved down to SA. But yeah Geos, Acaras, etc. etc. can't breed with Festaes. At least, there's no proof.
