Hey,
I work in the pet indusrty, and those types of fish are one of the stupidest human ideas to ever cross a mind. As a store we take a stand against all tattooed and dyed/injected fish, we wont carry them and we wont special order them for anyone. There are many techniques to dying/injecting fish with color, all of them very cruel.
Tattooing of a fish is self explaining, a machine that sends a needle with ink in and out of the skin a hundreds of times per second, I have plenty of tattoos personally and not a single one felt "good" to get, they all were uncomfortable, and sometimes painful.
Injecting, a needle with ink or dye is injected into the begining of the spine and the tail end of the spine, to create a fish with a shocking streak of color, too bad the color usually wears out in a few months, but that is of course only, if the fish lives through it, injecting weakens any fish subjected to it, good luck having them live more that 6 months.
And then Dying of fish. get a big old bucket of water mixed with dye, and leave the fish in it for alittle while, when they come out they will be green, purple, blue, and Pink. or you can just buy fish with that color naturally.............
There is a new type of fish on the market called GloFish Danios, they are a Zebra Danio that when they are in the egg stage of their lives they are genetically engeniered with jelly fish genetics, and i beleive also some have a type of coral genetic also to get different colors. so far there has been no indication only any cruelty in that practice, and the Zebra danio is one of the hardiest freshwater fish there are. This engenering hasnt seemed to cause them any problems as far as health or longevity. And actually now when bred together their genetics are breeding true. That part i find very interesting.
Any dyed/injected/tattooed fish are just wrong in my book, if people stop buying them people will stop making them, simple as that.
