The subject BD is the smallest of the three. I've owned her for 2 months now and she has gotten a shade or two lighter over the past two months. Eats like a pig and has grown an inch or more (from 6 inches to 7.5 inches now) and is otherwise doing great but I'm a little confused about her getting lighter... anyone else have this happen to them? Do share experiences please.
