I bought my FH when it was less than an inch for 7 bucks. As it grew it developed the generic black marks along its side. However, 7 months down the road all but one black mark on the tail fin (much like the male oscars) exist, and the fish is a silvery blue color. Ive noticed lately that the tail fin is developing more red/purple color but the body is bland. Will my fish become beautiful by chance or is it a dud?
