Yeah, it would be good to know what causes this.  It doesn't seem to be 
anything that affects adults or sub-adults, since they seem to retain good 
color in captivity for the most part...it must then be some factor that 
affects the eggs or young fry.  I don't believe it's in-breeding, since f1 
fish from probably unrelated wild pairs show this tendency.

So, you're right, that would seem to leave water, food, perhaps hormones 
exuded by adults in a confined environment??

Sorry, I will no longer use Wangenflecken for this fish).  Would it be 
acceptable to refer to them as blue-head caetei or A. sp. affin caetei 
'blue-head'?

Thanks,
