I wonder what would happen if I bought a picasso and released it into the wild? Of course I wouldn't because:
1. I don't have that kind of money.
2. That is just irresponsible.
However, it's just as irresponsible as those people creating these fish in the first place. I can't imagine what type of effects these cute little guys would have on the eco system if they happened to get out into the ocean. For example, there was a story on the lion fish that got released into the atlantic due to a hurricane, and now overpopulation of this fish is causing havoc to the local habitat (google search for article).
I think there's always a balance. But then again, when is something "too much"? I'd like to think we're all socially responsible, and not do something that is not in the best interest of the wider population.
But then again, we all have different perspectives and will never agree on what the right balance is. Personally, once the platinum clowns came out, I thought it was too much, and there was no longer a balance. The more "designer species" ORA comes out with, the more the balance will shift to the right. But again, that's just my opinion.
We can look beyond just the clown - I wonder how many people think cloning human is okay?
Anyway, I digress.
