This is interesting. There are two types, one genetically modified and the other is dyed in some way. To the best of my knowledge, and in recent conversation with the US distributors, they are still ILLEGAL to import into Canada. Of course if they are imported as simply Danios they would probably slip through customs and that is probably what is happening. True Glo fish are also very expensive. The Glo fish shown on Petsmart's site is too cheap based on cost and I would question weather they are the real deal.
I am curious enough to look into this further.....
You are quite correct Rastapus the "Glo fish" brand is most certainly banned in Canada due to the current ban banning the sale of genetically modified organisms without strict approval (e.g. Monsanto GM crops) and the company that make Glo fish can most certainly not afford the review process
EDIT: Remember the petsmart site is actually a US site and while Canadians are allowed to shop there, they will not ship every product sold to Canada including I would imagine Glo fish!
Just because they are in Canada does not mean they are legal. If they are shipped as regular Danio's customs would likely not pick it up unless inspected. The responsibility is put onto the shipper who would surely be aware they should not ship them to Canada. We have had a couple traded in recently so I know they are around but we don't support it. Smuggling in restricted fish can only negatively impact this industry for the benefit of very few.
I also heard that it would be illegal to bred them with out legal permission because they are patented by Yorktown Technologies. So if I was to legaly buy the fish and put it in my aquarium, and they reproduce, I can get screwed by the company. That's so stupied, they are suppost to be unable to reproduce, but there are reports that some can and will reproduce. As beautiful as it looks it sounds like this fish is more trouble than it's worth!
However, I would encourage everyone to please do everything in your power to NOT support dyed fish. I think sometimes the general public gets the two types mixed up, so please be aware of what you are buying. Dyed fish undergo painful, inhumane and sometimes fatal treatment to become 'coloured' and often the colours fade with time. So please, be careful what you buy, and in turn, support.
