Questionable Piranha Species?

[Talon]

I purchased 5 red belly 8 months ago. Bought them when they were very small. One of the 5 appeared a slightly different colour when they were bought. But now it has a significantly different colour to it. a Deep green colour, while the rest are blueish gray with silver spots. It appears to have developed faster. it is the same size, but has larger eyes and its teeth are always visible, other then that, no significant differences. Wondering if anyone could help me. I cant get any pictures atm, (sorry)

It could be the dominant one? But pics would help a lot. And I've also had reds and as juvis turn greenish then turn silvery with shimmer then turn darker as they got older.

probably different parents, different gene will have certain effect. without pictures our guess are as good as yours.

Heres a new picture. Yeh he does seem like the dominant one, its just odd how much he differs from the rest

Even from same batch you can get different shades just like some will have better red coloration than others.
