i doubt the teeth would really change, only one of my 4 have teeth sticking out. also with the color scheme stays the same sometimes they get a lot of black dots others just stay the silverish black color, that really depends on feed and health also genetics of the fish.I am relativly new to the piranha hobby only been at it for a few months i dont really need help with anything i was just wondering what my reds will look like fully grown. What i mean is what is their color scheme? are teeth very visible? things like that
thanks
