i was at the LFS the other day and was looking at some young JD (all between 2-3"). i noticed that some were a real rich dark pulple/black starting to show the blue/green scales they are know for, and others were significantly lighter, actually really pale almost greyish, but also starting to show nice scales. i was wondering if this is difference between males and felmales? or is this an indicator of which ones will be better looking when full grown?
