Just an update. One dead egg but the rest now have little heads and tails.
The water must be pretty right because my original concern was that their being netted out of a tank full of hungry cichlids then individually handpicked out of the gravelly mess and tossed into a never before tried egg tumbler was going to be too much mistreatment for them.... When you mentioned the water conditions being important to give the eggs a "shell" I was confident I was ok.
Basically, if water is suitable Malawi eggs are extremely robust!!
I was so pissed off when she spat out all those eggs but its amazing to now have a transparent view on the incubation of a Malawi brood! I guess that's why this hobby can be so addictive. You need the lows to appreciate the highs.
Thanks and Regards
