Negative, when dyed they tend to be more uniformThe first blue aro, and red, both look to be dyed, fake, whatever......
The one you could tell would normally look silver but were the light was hitting it it looked blue.
LOL, I've lost count how many Asian aros I have seen up close and personal over the years. Blue xback, 24K Gold, every shade of Red, and everything in between. Those fish both look fake to me, BIG time fake.
Ask at arofanatics, the boys from Singapore will set everyone straight.
