yours are pretty though
I'm sure there's a few other people who have them which will post pics
They aren't 'dyed'... They are physically no different than a regular tetra.
They use a gene (DNA Allele) then implant that into an embryo so the jellyfish gene they used will be expressed in the glofish and hence the fish would have the same color of a jellyfish.... Now since they've had these new DNA modified fish the fish have been able to be bred and the jellyfish color gene can be inherited by the offspring.
This technology was originally used in research to detect pollutants in waterways. When the fish would come into contact with a pollutant the gene would be triggered to express and the fish would glow... Then the research could detect unknown sources of pollution....
This technology has also been used for cancer research- when a cell is cancerous the allele for glowing is expressed and then they can tract the cancer....
The gene expression in no way causes harm to the fish..... It's like the difference in people who have brown vs blue eyes.... It all depends on which genes are present and expressed...
I'm majoring in animal science- pre veterinary medicine. And I find this technology wonderful, not only for animals but humans as well. It can be very practice for research and helping find cures....
I have a mini glofish tank and love it.... Although I also appreciate my natural tank. Also albinos look amazing with the glofish... I have an albino cat and ghost shrimp.
