Question Can glofish reproduce?

My question is the genetically modified zebra danio, the Glofish, ever been bred?

On the site it says that they are sterile, but I have seen pics of ppl claiming that they have glofry.

Is it possible to breed them? If so, are they like zebra danios?

They have a patent on them, so any glofry would be illegal. I have read several reports of people breeding them with regular zebra danios.

They are not sterile, definitely fertile. But as stated since they are trademarked it is illegal to breed them. The same is true for GM crops.

Breed them all you want, selling them is when you run into trouble, but technically depending on the patent if you were able to breed a mutation out far enough in them to a point the original patent no longer covered then you would be safe, but that wouldn't stop them from trying to sue you of course.

So would they only breed w/ regular zebra danios, or would a glofish x glofish pair reproduce?

They are still the same species regardless of what they are. Of course, they will still mate and breed, whether they have the glo DNA or not.

Maybe they tried and it didn't work (like Jurassic Park) or they want to discourage people from trying because if people start breeding them they will lose sales whether it is illegal or not.

I have two bright pink glofish fry. I had two pinks, two oranges, and two blues in a tank, and they spawned and I didn't even know it. If it wasn't for me not dumping the last bucket of water from a water change, I wouldn't have known at all. They sat in a bucket of dirty water for a week, when I went to dump it, I saw them swimming.

They reproduce just fine, and the babies are just as bright as the adult were, possibly even brighter because they are younger.
