A lot of people say that if you don't separate the mother and the babies once she spits, then she'll eat them. In some cases that may be true, but I've spawned my electric blues and the mother is in a 30 gallon watching over her fry (about a week old now) and she hasn't eaten a single one despite the lack of hiding spots (I was going to re-scape the whole tank to make her more comfortable before she spat, but she started to spit as I removed the last rock from the tank so I just left fake plants in). Your case may be different since you're dealing with Mbuna and I, Hap. Whatever you decide to do, good luck!
