how do the stripes on delhezis develop??? i've noticed that most young delhezis are virtually stripeless. do all of them eventually get stripes or are there a few that reamin stripeless. if so, why is this???

arg. there must be something i can do....maybe something that will increase color...i'll try carotene injections when he gets larger. not. well i noticed that mine has weak stripes too...but as i look closer to the tail i notice that the stripes seem to darken. since i'm new to polys can someone tell me if color is most intense at the head because the hormones for the color are produced there (this is the case for koi) or is there something i'm missing....
