The vein looking things are most visible in the blue areas and her belly. She is very sick and has been sick for months, if you look up "Molly" in search you will find many threads on her that will explain everything. Her colors have not changed at all which I guess is good. Those are her normal everyday colors. Yes she is thin, I have to force feed her and can only get the minimum into her (stubborn girl) She weighs 76 grams and actually has a bit of a pot belly. Anyway, can you see what I am talking about?
