Re: [Killietalk] xanthism

Actually, it is not uncommon for individuals of the  Epiplatys fasciolatus 
group to sport gold bodies until young adulthood, but they do not retain the 
coloration thereafter. I've seen this a number of times over the 30+ years 
I've been keeping species in this group, especially among Ep. lamottei and 
fasciolatus fasciolatus.
