I have adult RBs ranging in 7-10" with different color variations. I'd like to know if any other owners have this same effect on their Piranhas after crossing to their mature stage (loosing the black dots). Please post your pix up!!
Theses are group pix of my RBs with different color variations (gold, silver, black):
