GloFish: The Ill Effects

GloFish: The Ill Effects

I’m sure we’ve all seen the infamous “GloFish” by now, but what really causes that neon color? The original GloFish were injected with a neon colored dye to give them that coloration, but ONLY where the dye was injected. Most fish do not survive the injecting process. These days, most GloFish have been modified to now carry a gene that gives them their coloration that is passed on through their generations. Unlike the dyed fish, these GloFish are completely neon. The infamous color has a steep price though. It shortens the fish’s life span, makes them more prone to illness, and makes them more likely to succumb to stress. Is their color really worth that?

Would like some sources with that opinion. I have never noticed them to have a shorter life span .
Like other reviews, my fathers Glofish have not died prematurely or succumbed to illness. Also there is not enough hard evidence or cited sources for me to consider this accurate. Other than that it was interesting to read.
I currently own a tank with GloFish tetras, and absolutley none of them died from any sort of illness or died early. I've owned these same GloFish for 4 years. GloFish lifespan are generally between 3-5 years, which to me sounds like an ordinary lifespan for a fish. The original tetras used also live around this age, so technically there's no big difference in lifespan. Here's a quote from an article:

The fact that they are not dyed or injected is the reason Goulart will carry them in his store. He says he will not sell fish that are dyed or injected.



“It’s not healthy for them; it affects all their systems,” he says of dying and injecting fish. But those health concerns do not apply to GloFish, he says. “It’s just the skin that changes color. It doesn’t affect their systems,” Goulart notes.

Old GloFish that were injected may have been more prone to illness and dying premature, but this does not apply to the GloFish we have today in local fish shops. I made sure to do research on GloFish before handing any LFS my money, and I wish you could provide more hard evidence on your claims :).
As a friend of a GloFish keeper, I've never seen any of her GloFish live for less time than any of her average fish. If anything, her GloFish got sick less than her 'natural' varieties of the same species
Informative. I would like to see some sources cited where I can see this for myself. Good interesting read for sure.
