    +1 to what mommy1 said (apart from the wild caught part). I like wild-looking fish, but wish we didn't keep taking from the wild.

    I saw someone sharing this picture on facebook a while ago and promptly snuffed them out for supporting dyed fish... now I feel a little bad. In my defense, they do look suspiciously dyed.

    I vote no anyway. Honestly, if people don't like the way fish look in their beautiful natural forms they shouldn't keep them. They're an animal, not an accessory. The same kind of people that buy these will be the people that get their poodles fur dyed.

    Interesting points!

    I would clarify that on one OP the writer is correct, these fish are not dyed-- they are genetically manipulated in the egg to display these colors, spliced with the genes of a semi-fluorescent species of coral.

    They are far from natural, but on another post someone mentioned about breeding dogs and so on... Keep in mind a vast majority of the fish we own have been inbred over hundreds of generations to produce more vibrant colors. Discus' natural color is black and muddy brown. Same with angelfish. Goldfish (carp) are brown, and their shapes aren't even the same as what we buy in the fish store. And the whole koi spread of varieties are genetic mutants inbred over thousands of years.

    There is very little natural about the fish we keep, or the dogs or cats for that matter.

    What bothers me the most is that they spliced genes with another thing that wasn't even a fish. Ya know, like tomatoes carrying frog DNA or something like that.

    The reason the scientists were so adamant in producing this color in angelfish is supposedly angelfish do not naturally carry the gene for any sort of "red" or reddish pigments.

    These angelfish are 3500$ Canadian each, in case you want one. And yeah, as with anyone creating a new variety of fish, thousands are culled before the desired traits appear. All new varieties are ruthlessly put through this process, and these mutant angels were no different. :(

    Very true. Yeah that's interesting actually. My parents' pond has had goldfish in it for 30 years. They aren't fed or "looked after" really, other than an annual "drag out" of all the overgrown weed. There used to be lots of orange and white fish and they bred a lot over the years. The heron was a regular visitor though and any brightly coloured fish were easy pickings. My folks thought the heron had got them all and after several years decided to reline the pond and make it a bit bigger (with the intention of re-stocking it). Upon draining the pond they found it still had fish in it...lots of them...but they were all BROWN! Natural selection in action...reverting back to originals over 30 years.

    I found this fascinating.

    I know were talking fish here but something firefly brought up about the goldfish reverting back, studies have shown that dogs left alone after a few generatins will begin to look like Wolfs again.

    Firefly that's fascinating! What a great story. :)

    @Firefly-- that's an awesome story! Did you happen to see them up close?? I wonder if they reverted to their original shape as well. It's not very different, just their bellies are ever so slightly more flat so they can scurry the bottom better, I guess. This is amazing! :)

    @Steeler-- I've heard of this too. You can see it if you go to a city where there are a lot of wild dogs. Many are completely feral but have collars, meaning they belonged to someone not long before.

    You might find this an interesting read if you're not familiar with it.
    Belyaev Temperament Breeding Experiment: https://www.americanscientist.org/is...ge=3&css=print

    A summary of this is that foxes were (and still are being as the experiment continues to this day) selectively bred for 40 years. The selection process was temperament only. The submissive (domestic-potential-behaviours) foxes were bred together, and the aggressive (wild-potential-behaviours) foxes were bred together. Again, to reiterate...the only selection basis was temperament.

    Look what happened to the docile ones.

    A few developed floppy ears as well (more common in domesticated species).

    I find this amazing. Genetic linking of behavioural traits and physical traits.

    The orange and white fish were "normal" shaped, so no, it was just the colour change really.

    Doesn't really do anything for me, but then I've never really been one of the pink girly girls types.

    However, I do see the value in breeding and some experimentation with genetics. Being able to understand what kind of genetics are stable and which are not is quite valuable. Genetics experimentation has led to developments in better understanding diseases like Down Syndrome and Muscular Dystrophy type diseases.

    I believe there is probably a long line of ethical debate when it comes to what is acceptable and what isn't.

    For me.. I don't support modifications that are a detriment such as dogs that need help cleaning themselves, or deformed bodies that lead to health issues. I don't mind too much just coloration, since that would kind of make me a hypocrite... I find some of the apistos and rams bred to enhance coloration attractive. Orange goldfish don't bother me.. but the wonky eyeball ones do.
