We have a fair number of Mchenga conophoros from Lake Malawi. The first batch we received all appeared healthy, as did the first clutch of offspring. However with in all subsequent clutches 2/3rds of the offspring have an odd mutation where it looks like they are missing their cranium or foreheads. We originally thought this was "hole in the head" but we never see little holes, only the whole thing missing, and the rest of the fish looks healthy. None of our other species have this problem and they share the same water system. Currently we are thinking it is either a genetic mutation or a lack of some vital minerals in the water.
Has anyone seen something like this?

I have seen skeletal deformities around the head when the nitrates are higher than they should be. Mine were lethrinops and I did not have enough rounds of fry to be sure that was it or the parent had a defect they were passing along to some fry but it was not visible in the parents.
