Hello, I'm looking for someone who has knowledge on dyed arowanas. I have the option to rescue one for free, and I will be placing it in a 250gal tank, which may be upgraded to a bigger size down the road as the arowana grows. What I don't understand is that my LFS told me someone had dyed the arowana. Is this ethical? Are there complications that could arise out of this? It's a beautiful blue arowana, and I don't mind that the color is not natural, but what I don't understand is the concept of dying it, and if that could cause any issues.
