So, as I've long suspected (but hadn't managed to confirm)these are NOT Enterochromis paropius. Per Peter George and Michael Liu, they actually look to be Yssichromis piceatus. I deposited some of the latest group of fry with Lisa at Super Cichlids this week in hopes of spreading them around and maybe getting a definitive ID on them. I did see some real Enterochromis paropius there, and they're lovely fish, but definitely NOT these. Lately I always have at least one female holding and the spawns have been larger.
